SPH Engineering has launched a new product to make bathymetric surveys of inland and coastal water.

The system — an unmanned aerial vehicle (UAV) integrated with an echo sounder — is time- and cost-efficient. It is suitable for mapping, measuring and inspecting tasks as well as environmental monitoring.

The system allows field workers to collect data with high accuracy quickly. It is easily transported, quickly deployed and twice as cost-efficient as traditional methods.

The UAV/echo sounder system can be operated in hard to reach locations, and unsafe or hazardous environments. Locations not reachable by foot or that are dangerous for a human (steep coasts, mining pits, contaminated waters, terrain obstacles, etc.) as well as waters of ponds, lakes, and canals can be reached by the drone.

“Since autumn 2018 we have been getting bathymetry-related requests,” said Lexey Dobrovolskiy, CTO of SPH Engineering. “Analyzing about 150 inquiries, we have come to the conclusion that a drone-based solution could open a new business opportunity for drone service companies to do bathymetry surveys of coastal and inland water, especially those for industrial needs.

“Compared with a standard approach using a boat or an unmanned surface vehicle, a drone could save a lot for its user,” Dobrovolskiy said. “An echo sounder itself could be integrated into a client’s drone with no need to purchase additional equipment. Moreover, it is small and easy to transport and operate. At the same time, such research method guarantees data accuracy and employee safety.”

Cobham Explorer 323 and Explorer 6075LX terminals receive Inmarsat type approval

Cobham SATCOM and Inmarsat have announced the type approval of two new land satellite terminals. The low-profile vehicular Cobham Explorer 323 BGAN terminal and the auto-point “fly-away” Cobham Explorer 6075LX VSAT terminal are now fully operational on the Inmarsat network with commercial shipments of each beginning immediately.

The new Explorer 323 terminal represents the first class 12, electronically steerable terminal for use on Inmarsat’s L-band Broadband Global Area Network (BGAN). It combines the slimmest form factor of any vehicular BGAN terminal with a number of new innovative features and sets a new standard in robustness due to its lack of moving parts. In conjunction with Inmarsat’s highly reliable network, offering up to 99.9% uptime, it promises a new standard in mobile communications to organisations operating in remote locations across a wide array of industries.

The class 12 terminal features speeds of up to 384kbps, support for BGAN (data and voice) and BGAN M2M (data) operations, and an integrated antenna and receiver, meaning only a rooftop unit is needed. Additionally, the Explorer 323 has an integrated Wi-Fi Hotspot for setup, management and data access. Developed to integrate seamlessly with Cobham’s PRISM PTT+ offering, the Explorer 323 will enable telemetry and voice communications as well as other uses in remote rail operations, utilities, mining, aid and NGO operations, agriculture, public safety and emergency response.

Inmarsat has also approved the new auto-point ‘fly-away’ 0.75m Cobham Explorer 6075LX VSAT terminal for its high-speed Ka-band Global Xpress service. The new terminal offers the most reliable and stable connection in its class and features a simplified design, enhanced usability, quick setup and built-in WiFi. With a dynamic auto-pointing correction the terminal maintains its connection even in windy conditions or when pushed or moved, optimising its connection constantly. The Explorer 6075LX also features a considerable reduction in weight versus the Explorer 5075GX for greater portability and will support high-bandwidth applications in broadcasting, resilience and field-office operation.

“We are proud to offer these two game-changing terminals to our partners and customers,” said Mike Carter, president of Inmarsat Enterprise. “Their launch follows an important period of industry consultation, innovation and collaboration between Cobham and Inmarsat. With the Explorer 323 ideal for vehicular tracking and communications and the Explorer 6075 optimised for high-bandwidth operations, both terminals improve upon their predecessors and are set to make ultra-reliable connectivity easier to access in the remotest areas, wherever it is needed most.”

“These two new terminals from Cobham prove that there continues to be innovation occurring in both our L-band and Global Xpress networks,” said Todd McDonell, president of Inmarsat Global Government. “For government users, the 6075LX (or GX6075) provides a fast to set up, easy-to-use, automatic acquisition broadband terminal ideal for first responders who need to access communications at a scene quickly.

“In addition, the Explorer 323 provides government users with a way to maintain on-the-move connectivity regardless of the situation,” McDonell said. “When fixed networks become disabled or degraded, due to events such as natural disasters, the Explorer 323 provides an ideal, low-profile system for routing radio and data connectivity and can be integrated with the emergency services’ existing radio and data networks. We thank Cobham for bringing these products to market. We believe that they will help to deliver new capability for a number of government departments and agencies.”

Inmarsat owns and operates mobile telecommunications satellite networks around the globe, and holds a multi-layered, global spectrum portfolio covering L-band, Ka-band and S-band.

Inmarsat has provided global, L-band services for many decades, which are used by governments, the maritime and aviation industries, and commercial users on land, in sectors ranging from mining and agriculture to rail and transportation.

The frequencies used by Inmarsat to deliver these services are different to those used for GPS/GNSS. All terminals approved for use over Inmarsat’s L-band network (and their other networks) conform to international standards.

In the case of GPS, Inmarsat has exceed these standards by a considerable margin.

New Matrice 300 RTK and Zenmuse H20 series cameras ready for new generation of work, including digitalization and artificial intelligence (AI)

DJI has unveiled its most advanced commercial drone platform, the Matrice 300 RTK (M300 RTK), along with the Zenmuse H20 Series, a hybrid, multi-sensor camera.

DJI engineered the all-in-one, high-tech solution for areas of work never explored before in precise aerial inspections and data-collection missions.

“With the M300 RTK flying platform and the Zenmuse H20 camera series, we are providing a safer and smarter solution to our enterprise customers” said Christina Zhang, senior director, Corporate Strategy at DJI. “This solution sets an entirely new standard for industrial UAV solutions, significantly enhancing operations across public safety, law enforcement, energy, surveying and mapping as well as critical infrastructure inspections.”

The M300 RTK is the first DJI product that integrates modern aviation features, advanced AI capabilities, six directional sensing and positioning system, a UAV health management system, and 55 minutes’ flight time.

The drone platform has AES-256 encryption and an IP45 weather-resistant enclosure. It has a built-in all-new OcuSync Enterprise transmission system that provides a triple-channel 1080p video transmission signal reaching up to 15 km away.

The M300 RTK can support up to 3 payloads simultaneously and has a maximum payload capability of up to 2.7 kg.

“For our teams working in the oil & gas industry, performance and safety are not optional,” said customer Adam Serblowski, Robotics Theme Lead at Shell. “We cannot compromise on our pursuit of utilizing the best and most efficient tools available. The DJI Matrice 300 RTK proves to be an ideal upgrade over the existing DJI product line, and it helps us to further enhance the benefits of our drone programs. Our productive partnership with DJI will continue to help elevate safety in the world’s largest industry.”

With the Zenmuse H20 Series Camera

Combined, the M300 RTK and Zenmuse H20 Series solution offers users two intelligent ways to collect data:

• Smart Pin & Track. Intelligent functions that enhance synchronization of aerial intelligence in coordinated missions. It includes PinPoint, a function that allows users to mark the subject of interest and instantly share the precise location data to a second operator or if necessary to ground teams via DJI FlightHub; and Smart Track, which allows users to automatically detect and track a moving object, even at extreme distances, while synchronising the subject’s dynamic location in real time.
• Smart Inspection. A new set of features developed to optimize routine data collection missions such as power lines, railway and oil and gas inspections. It consists of Live Mission Recording for recording sample automated missions in real time; AI-Spot Check, which enables data collection from exactly the same location every time, greatly improving the accuracy of automated missions. After photos from a sample waypoint inspection mission have been recorded, operators are able to mark the subject of interest. During subsequent automated flight missions, AI algorithms perform a comparison between the marked subject and current live view, thus correcting the camera orientation accordingly to deliver accurate and consistent results; and Waypoints 2.0 — an improved mission planning system offering up to 65,535 waypoints, while supporting an array of consecutive actions, 3rd party payloads, and more.

Aviation-Grade Situational Awareness. Inspired by today’s modern aircraft, the M300 RTK features a Primary Flight Display (PFD) that merges real-time flight and navigation data into one integrated display. Besides standard telemetry data like altitude and speed, the M300 RTK PFD provides obstacle data for visualising nearby obstacles during flight, enabling pilots to adjust flight trajectory if needed. These enhancements allow users to keep track of the aircraft while further enhancing the pilot’s situational awareness.

Dual-operator mode. New to DJI’s commercial drone platforms and exclusive to the M300 RTK, is Advanced Dual Operator Mode – multi-pilot control protocols that enable the execution of missions with enhanced safety, reliability and flexibility.

The M300 RTK, when controlled by two pilots, gives each pilot equal access to gain flight-control priority, the transfer of which is displayed by a series of icons on the DJI Smart Controller Enterprise. If one pilot becomes compromised or their controller loses battery or connection, the other pilot gains full control over the M300 RTK and its payloads.

When training new pilots, the teacher/main pilot can safely take over flight control if necessary.

Improved safety and reliability

The M300 RTK comes with new and improved safety and reliability enhancements, including:

• AES-256 Encryption: for secure data transmission of the command & control uplink and video transmission downlink.
• AirSense (ADS-B technology): for enhanced airspace safety.
• Anti-Collision Beacon: for increased aircraft visibility, especially in low-light conditions.
• IP45 Protection Rating & Self-Heating Battery: for adverse weather conditions (-20 to 50° C).
• 6 Directional Sensing and Positioning System: offers a maximum detection range of up to 40 m horizontally, with options to customize the aircraft sensing behavior via DJI Pilot.

As with modern-day jetliners, the M300 RTK offers an integrated UAV Health Management System (UHMS) to optimize fleet maintenance. It records the aircraft’s flight data throughout its entire lifecycle, and utilizes the drone’s hardware and software systems to understand current aircraft performance and determine when it should be serviced. Taking advantage of this new system, users can get a quick overview of all critical aircraft systems, manage firmware updates across an entire fleet, track pilot hours and review flight missions.

DJI Zenmuse H20 Series

The new camera payloads are designed to improve mission efficiency. The Zenmuse H20 series offers DJI’s first Hybrid multi-sensor solution, allowing capture of any kind of images for industrial applications and public-safety missions where efficient time management and immediate access to multiple layers of visions are paramount.

The H20 Series is IP44 rated, which protects enclosures from splashes of water from any direction.

The H20 series comes in two versions:

• The H20, a triple sensor with a 20-MP, 23x hybrid optical zoom camera, a 12-MP wide camera, and a laser range finder covering distances from 3 to 1200 meters
• The H20T, a quad sensor that adds a 640 x 512 radiometric thermal camera, allowing operators to see what is invisible to the human eye using high thermal sensitivity at 30 frames per second video definition.

Integrated user interface

To enable pilots to operate so many sensors at once, the accompanying DJI Pilot app interface was redesigned. The new user interface lets pilots quickly switch between cameras and simplifies the process of zooming in and out by letting pilots preview the zoom field of view on top of the wide angle or thermal camera footage.

With a multi-sensor integrated user interface, the Zenmuse H20 series allows users to smoothly switch between wide, zoom or thermal cameras. It also includes features for maximum flexibility when used on time-sensitive missions.

• High-Res Grid Photo: Captures in one snap detailed imagery of defined subjects with the help of a custom grid. The images can be stored for later detailed inspection.
• One-Click Capture: Captures videos or photos of up to three cameras simultaneously without having to manually switch between camera views or repeat a mission.
• Night Scene: Gains clearer visibility when lighting conditions are not optimal.

The M300 RTK and Zenmuse H20 series are available for pre-order from official DJI Enterprise dealers and will start shipping in Q2 2020.

Skyward has released a new risk assessment tool for its Aviation Management Platform, which is designed to help drone program managers proactively identify and document critical risks to an operation.

For assessing risk, users answer a series of risk questions developed by Skyward’s drone experts and based on aviation best practices. Each answer is assigned a risk level: low, moderate or high. As each question is answered, an overall risk summary score is generated based on the highest level of risk present, Skyward said.

Users can also add mitigation for any risk level by adding explanations and adjusting the risk levels. The mitigated risk will be noted in the summary, and the note will be synced across the Skyward software platform.

Skyward, based in Portland, Oregon, develops drone programs for industries such as construction, industrial inspection, media, insurance, real estate, mining, precision agriculture and more. Skyward was acquired by Verizon in 2017.

The U.S. Department of Transportation’s Federal Aviation Administration (FAA) today announced the eight companies that will assist the federal government in establishing requirements for future suppliers of Remote Identification (Remote ID).

Remote ID will enable unmanned aircraft systems (UAS), commonly called drones, to provide identification and location information while operating in the nation’s airspace.

The FAA selected the following companies to develop technology requirements for future Remote ID UAS Service Suppliers (USS):

• Airbus
• AirMap
• Amazon
• Intel
• One Sky
• Skyward
• T-Mobile
• Wing

These companies were selected through a Request for Information process in December 2018.

“The FAA will be able to advance the safe integration of drones into our nation’s airspace from these technology companies’ knowledge and expertise on remote identification,” said U.S. Transportation Secretary Elaine L. Chao.

This initial group will support the FAA in developing technology requirements for other companies to develop applications needed for Remote ID. The applications will provide drone identification and location information to safety and security authorities while in flight.

The technology is being developed simultaneously with the proposed Remote ID rule. Application requirements will be announced when the final rule is published. The FAA will then begin accepting applications for entities to become Remote ID suppliers. The FAA will provide updates when other entities can apply to become qualified Remote ID USS on FAA.gov.

Drones are a fast-growing segment of the transportation sector with nearly 1.5 million drones and 160,000 remote pilots now registered with the FAA. The agency’s ability to develop Remote ID technology simultaneously with the rule enables the FAA to continue to build on a UAS Traffic Management (UTM) system that has demonstrated global leadership through the small UAS rule and the implementation of the Low Altitude Authorization and Notification Capability (LAANC), which automates the application and approval process for most UAS operators to obtain airspace authorizations.

German drone manufacturer wins two prizes at renowned Lake Kivu Challenge in Rwanda

On May 5, the organizing committee of the Lake Kivu Challenge announced the results and named Wingcopter the winner of the Emergency Delivery category.

Wingcopter also received a special award for its safety procedures. As a winner, the company receives a prize money of GBP 65,000.

The Lake Kivu Challenge is a collaboration between the Government of Rwanda, the United Kingdom’s Department for International Development (DFID/UKAID), and the World Bank Group. The drone competition sought to demonstrate use cases for unmanned aircraft systems (UAS) on the African continent.

The challenge took place at the 2020 African Drone Forum in Rwanda in February — a first of its kind on the continent. Hosted by the Rwandan government and inaugurated by President Paul Kagame, the forum showcased advances in autonomous drone delivery — advances that can make a significant difference for isolated communities and rural areas across Africa.

The challenge received 92 applications from 35 countries. Only the top 10 drone companies were invited to put their drones and operators to the test through real-life scenarios at Lake Kivu in Western Rwanda.

Throughout the three weeks of flights, Wingcopter was able to impress a panel of judges with perfect mission performance. This included fully automated delivery of an emergency package from a droneport on the mainland to Bugarura Island and a secure return landing.

The roundtrip, beyond-visual-line-of-sight-flight (BVLOS) was 40 kilometers and was completed without a battery swap. Wingcopter drones were able to complete the one-way route to the island within 12 minutes, a drastic reduction compared to more than 50 minutes by boat.

The package drop-off required no landing or human interaction, an attribute of Wingcopter’s innovative winch mechanism. Wingcopter had already successfully deployed a similar type of on-demand vaccine delivery to 19 remote villages in Vanuatu on behalf of the local Ministry of Health and supported by UNICEF.

“We are very proud to be winners of the Lake Kivu Challenge, as this challenge and the African Drone Forum embody the innovative spirit of humanitarian aid and the African drone community as well as the great potential for sustainable drone deployments,” said Tom Plümmer, CEO and co-founder of Wingcopter. “We strongly believe that Wingcopter drones can leapfrog existing infrastructure by delivering significant social and economic value in Africa and beyond.”

“Wingcopter’s goal is to develop long-term partnerships with local governments, private sector and donor organizations throughout Africa,” added Selina Herzog, project manager at Wingcopter. “It is through these partnerships that we will accomplish the knowledge-sharing and training of the local workforce, ultimately empowering local stakeholders to take over and scale operations. We want our technology to give back to the communities where we operate and create new perspectives.”

The African Drone Forum created a unique platform to tell the Wingcopter story and exhibit its technology to more than 1,000 key players within the international drone and humanitarian ecosystem, allowing immense networking opportunities with the potential for future partnerships and business deals. An initial memorandum of understanding with a Rwandan startup has already been signed; others will likely follow.

Wingcopter recently announced a commercial partnership with UPS Flight Forward to jointly develop the next generation of package delivery drones. The combination of UPS’ experience in logistics and its global network with Wingcopter’s contactless drone delivery technology will put the two companies in a better position to contribute to the fight against the COVID-19 pandemic. Wingcopter is preparing multiple coronavirus-related projects.

With more than 3 million people infected around the world, the coronavirus pandemic is pushing health authorities to research and develop new ways to react to critical situations, according to drone company Quaternium.

Public and private organizations are racing to develop experimental treatments and vaccines to fight COVID-19. At the same time, many local companies are trying to think outside the box to find ways to minimize the effects of the crisis. “Our current situation has opened up opportunities for innovative solutions, and we are best seeing them within the drone industry,” said Alicia Fuentes, CEO at Quaternium.

Drones have been deployed in the effort to contain the spread of the pandemic. “We’ve seen drones distributing public information, like voice messages, to those not following social distancing measures as well as delivering medical samples and spraying disinfectants to urban areas,” Fuentes said.

Unmanned solutions are easy to operate and can be quickly mobilized. “In addition to reducing the risk of health of sanitary workers, drones also get to unreachable places; they have become a versatile tool for managing this health catastrophe,” Fuentes said.

In Europe, several startups like Quaternium, Drone Tools and Manna Aero, and in the U.S. and Canada, companies such as Zipline and Draganfly are all exploring how they can help in their regions and neighboring countries to decrease the aftermaths of the pandemic and save more lives.

Quaternium demonstrates drone spraying

Quaternium has successfully been testing its hybrid drone, HYBRiX, to spray disinfectant products in Spain, showing how drone technology may serve in critical situations and how the company can support to public authorities to help end the spread of the virus.

The company has also demonstrated aerial logistics solutions by delivering essential items to people in critical situations. Long-endurance drones can deliver supplies specifically for COVID-19 efforts, such as masks and gloves to first responders. HYBRiX can also deliver medicine to patients who can’t safely get to a pharmacy.

In the U.S., police departments are using drones from Impossible Aerospace to limit personal contact and share COVID-19 information, to reach out to homeless people (who are particularly at risk for coronavirus) and to monitor and enforce social distancing.

These are some of the areas where drones are being used to fight COVID-19.

Delivery drones

Due to COVID-19 being so contagious, it’s safer if human-to-human contact is minimized. UAVs are proving to be a valuable tool when delivering medical samples and essential items to health personnel. Several drone companies have made tests showing the crucial role that unmanned logistics can play against the spread of COVID-19.

Inform and prevent

“In the last weeks, we have seen speakers being mounted on drones to help inform people outdoors and prevent public gatherings. Drones can also be found flying with banners advising people on how to be more precautious when going outside,” Fuentes said. The mobility and flexible use of these UAVs make the mission of security agencies simpler, while avoiding close contact with the population, she said.

Aerial spraying and disinfection

First in China and now in Europe and the U.S., agriculture drones — originally designed to spray liquids on crops — are being adapted to spray disinfecting chemicals in public spaces and impacted areas. Experts have discovered that coronavirus is mainly transmitted by touching contaminated surfaces. This new virus has shown to be very contagious and resistant, staying on some surfaces up to 30 days, which makes disinfectant spray vital to helping reduce transmission mechanisms.

The battle with COVID-19 has just begun. Cases are continuing to rise in and outside of Europe. “Now more than ever, public authorities and private companies need to join forces in order to grow stronger and overcome this pandemic together,” Fuentes said.

Open space: the final frontier. These are the voyages of the professional surveyor and their crew. Their mission: to explore and survey strange new lands. To retrace old boundaries and to create new parcels and subdivisions. To boldly go where no one has gone before (unless it has been previously surveyed and platted…)!

With a nod to Star Trek fans (and apologies to Mr. Roddenberry), the surveyor has been the terrestrial version of the Captain Kirk and Science Officer Spock, exploring existing and uncharted territories. While most surveys completed in the modern day are retracements of previous parcels, there are still areas where surveyors are completing various tasks where no one has been before.

There are very few instances where a survey is performed near others. By this simple fact, one can argue that the surveyor is the original social distancer. The real question, however, lies within the determination of the value of the surveyor and if the work we perform is an “essential service.”

This article is not attempting to debate the value of the surveyor versus all the first responders, doctors, nurses, healthcare personnel and the hardworking employees doing their best to keep up with our basic needs. We are here to discuss the challenges faced by the surveyor and how technology has provided much-needed tools for crossing this abyss of doom and despair called COVID-19.

But first, let us talk about how we arrived at this extraordinary time for nearly everyone on the planet.

Worldwide upheaval or some close facsimile thereof

Every generation has a historical event, moment or era for which they remember exactly what they were doing:

• “Greatest” generation (born before 1924): the Stock Market crash of 1929 and subsequent depression
• “Silent” generation (born 1925-1945): Pearl Harbor and World War II
• Baby Boomers (born 1946-1964): Korean War, the Kennedy assassination, the Moon landing and the Vietnam War
• Generation X (born 1965-1980): Reagan assassination attempt, Challenger explosion, death of Princess Diana
• Millennials (born 1981-1996): 9/11, Aurora and Sandy Hook shootings

Unfortunately, the series of events leading up to the nationwide shutdown because of the COVID-19 pandemic will unseat most of those events and eras. While previous pandemics (for instance, the Spanish flu of 1918) struck and killed many more people, the mobility of today’s population coupled with instantaneous media coverage provides a much different environment for this situation.

Obviously, we are not alone, and this virus has spared few countries and races. Different cultures across the globe have adapted for the pandemic in a variety of ways, and the U.S. has faced the same challenges across our diverse environments.

Depending on where one is located, they face a different set of challenges due to the pandemic. Several heavily populated urban areas are subject to a strict lockdown while states with mostly rural areas are less restrictive. One size does not fit all when dealing with limiting public exposure to others, but let us leave the debate of how much restriction is needed to the scientists and public officials. Many today do not agree with the rules we have been dealt with in going about with our lives. That is a discussion for another time and different forum.

Instead, let us discuss what we face going forward with our “new reality” of some form of social distancing and how the need for surveying and geospatial information remains for a large portion of this world. We must simply adapt to this situation with the adoption of new technologies and a revamped workflow.

Everything changes, whether we like it or not

The surveying profession is not unlike many other service-oriented and public-serving occupations, even with most of the field work being performed in solitude. We still deal with clients, governmental agencies, other consultants and the public.

The COVID-19 pandemic has changed the way we are now interacting with those outside partners with technological advances and modified communication conduits. Many of these methods existed well before this situation, but the rapid advancement of the pandemic forced many companies and employees into adapting very quickly.

Surveyors are no different, so let us run through the changes we have seen within the industry.

Project communication

The biggest challenge facing most surveyors in dealing with the pandemic atmosphere has been communication. Whether it is with employees, clients, government agencies or other consultants, communication has been affected mostly because of the elimination of face-to-face opportunities.

Technology to allow remote communication has existed for many years, but not many of us have taken advantage of it because of the convenience of in-person interaction. Who does not want to leave the office to meet with a client, shake their hand and close the deal? Or have the client come to your office and go over the intricacies of a complex survey?

Regardless of whether one is introverted or extroverted, human contact has always helped establish and solidify relationships. For most of us, this is how business has always been done, be it your client or your employees.

Obviously, the biggest area affected has been daily interaction with employees. Controlling workflow, handling projects and troubleshooting any situation is more difficult when the team is not physically in the same location. If a team member is overwhelmed, another one can immediate meet with them and help. Work is easily passed between teammates with little effort.

But working remotely? That takes more effort, consideration and technology to accomplish. Yes, video conferencing has been in place for many years, but mostly in large companies and only implemented it in a dedicated conference room. Not many employees were previously afforded a webcam, microphone and speakers along with the necessary software; all of these components are now standard issue. For many, programs like Zoom, Skype and Microsoft Teams are now a critical communication tool for timely and efficient sharing of information.

What about communication with field crews? Many would say that even a pandemic would not change how we stay in touch with field crews, but even these relationships have been affected. While there are survey companies operating with limited physical contact as a norm (large firms with projects regionally or nationwide), most surveyors still have a substantial amount of direct communication between field and office. This situation has forced many firms to take precautions, with crew members only handling specific pieces of equipment or performing a thorough cleaning if sharing during a project.

Project documents and files have typically been been handled manually with some electronic data files being transferred via email or internet. Depending on the size of the original document, having a full-size paper copy of a previous survey or subdivision plat has advantages to looking at a PDF image on a tablet or computer screen while in the field. Many companies outfit their field crews with 11 x 17-inch printers to be able to print larger detailed areas of bigger documents. Additional care must be taken if these items will still be used for field operations.

The transfer of data between office and field has become faster, more efficient and safer with technology. As data collectors have become more capable, direct connections via the internet to cloud storage is making transfer of project files and photos faster and more secure by providing immediate backup to guard against data loss. What used to take a trip to the office, connecting to a computer and downloading is now done in a matter of minutes without leaving the job site.

Field personnel are also benefiting from technology within our devices. Apps like FaceTime and programs like Microsoft Teams provide a gateway to video chatting so teammates can discuss projects in real time. Shared pictures, computer screens and face-to-face interaction provides an avenue to more effective communication and enhancing relationships between team members.

The pandemic has forced many surveyors to adapt and learn several new apps and programs to connect in new ways; however, this pandemic has also affected how we go about our field operations, too.

Enhanced data collection

Not many of the surveyor’s field activities are affected because of social distancing requirements, but the pandemic has forced our profession to be compliant with the new rules in case we are in proximity with others. Newer technology, using both terrestrial and aerial platforms, are now being utilized by more surveyors for their data collection needs.

Train employees now. As many companies have seen a slowdown in work due to pullbacks from projects moving forward, now is the time to get employees trained with the new technology and software to be better prepared for when the market comes back.

Using photogrammetry tools. Photogrammetry, lidar and laser-scanning systems are being purchased and implemented for everyday use and not just “special” projects with larger budgets. Not only are surveyors finding it keeps them further away from other people, it also allows for more efficient data collection and representation of existing conditions.

Flying unmanned aerial vehicles. UAVs continue to grow in popularity, and like the other technology discussed above, many firms are investing in becoming remote pilots and implementing aerial photography and lidar into their workflow. Previously, most surveyors (and the general public) would use Google Earth, Bing and other resources for aerial imagery to gain a better perspective on their project sites. Vendors are coming out with aerial products with more recent flights at a higher resolution, but do not offer the ability to extract reliable topographic data easily. In-house UAVs provide more flexibility and control over the information needed, and many are using their downtime to become familiar with aerial products.

Dipping toes into remote sensing. Another sector of surveying equipment seeing increased use during this situation are new total stations with remote-sensing capability. Many surveyors may not have the need for a standalone laser or lidar scanner, so several manufacturers have introduced a total station that provides limited remote sensing for everyday use. While the built-in scanner is not nearly as robust as a traditional remote-sensing unit, it provides enough capability and accuracy for most users. This intermediate step of remote sensing helps a firm decide how much scanning they will produce and if an investment in a full function unit is right for them.

Upgrading GNSS receivers. We would be amiss if we did not mention that more surveyors are now upgrading their GNSS receivers to take advantage of more constellations, integration with IMUs and increased computing power of the latest data collectors. Some surveyors who are not as economically affected during this pandemic are taking advantage of great deals on new equipment and using this time to increase their capability and efficiency. As more satellite vehicles become available, the ability to gain accurate and precise locations is better than ever, so staying ahead of technology is still important in these times. We will continue to see more gains with L5 and L1C signals from the new GPS Block III satellites within the next few years, so staying current now is very important.

QA/QC — The electronic method

One trouble spot seen within the new paradigm is the ability to provide a thorough quality assurance/quality control (QA/QC) process on all surveying operations. Without the ability to print/plot original surveys at full scale, it becomes a more difficult procedure to review and analyze information on a computer screen.

The monitors used for drafting and calculations are getting bigger, but studies have shown the human eye will focus differently on an electronic screen compared to a survey on paper. There must be many other professions and occupations using similar technology who have yet to solve the QA/QC dilemma. Hopefully, our industry will find a way to help address this issue and provide guidance.

More connected than ever, yet still so alone

The COVID-19 pandemic of 2020 (let us hope that is all it encumbers) will be forever etched in our memories as frightening and unbelievable. More than 100 years has past since the last pandemic of this proportion has overwhelmed our population. We are much more advanced in our education of health, medicines and technology than the previous event, yet we were caught off-guard by the speed in which the virus spread throughout our lands. It taxed most of our health infrastructure beyond its limits and took its toll emotionally and financially to most of the population.

We were forced to adapt very quickly to a new norm of working remotely and independently of our co-workers and teammates. Did it hurt our productivity and profitability initially? Absolutely. Were our employees forced to learn new ways of doing their work and communicating by other means. Yes, they did. Was there a need for rapid troubleshooting of new procedures and task management? Of course. Has every transition of remote work been a success story? I doubt it, but it was not for lack of trying.

We are doing the best we can, and the surveying profession is rapidly trying to adapt. Like the rest of the world, the surveying profession will not be the same coming out of the restrictions placed upon us because of the pandemic. We have learned more about ourselves and how capable we are with tools we have. We also learned how we will transition with these skills into new technology not invented yet.

Surveyors are a tough bunch, so the social distancing and adaptation required to survive the COVID-19 pandemic of 2020 — while not easy by any stretch — has been handled with grace and professionalism. I would say to bring on the next one, but would rather this pandemic be in our rearview mirror quickly and not see anything like it ever again.

Xsens, manufacturer of motion-tracking modules, has launched real-time-kinematic (RTK)-compatible motion trackers. The development is designed to bring centimeter-accurate positioning within reach of a new generation of affordable commercial devices.

The RTK extension to conventional satellite positioning signals reduces the maximum positioning error from around ±1 meter in standard commercial GNSS receivers to typically ±2 centimeters. Companies developing innovative new products in non-military markets such as smart farming, autonomous vehicles and coastal maritime equipment have been keen to take advantage of high-precision RTK capability to enable new applications and more automated functions, according to an Xsens press release.

The MTi-680G is a new product in the Xsens MTi 600-series. The MTi-680G, an integrated GNSS/inertial navigation system (INS) module, features an integrated RTK GNSS receiver, as well as providing synchronized 3D attitude (tilt, inclination) and heading outputs.

The new MTi-680G also features upgraded firmware that substantially accelerates the module’s internal signal processing compared to non-RTK modules. Synchronizing the global position coordinates with the module’s attitude, heading and velocity outputs, the MTi-680G can provide a comprehensive positioning and navigation output for any carrier device, including of devices such as drones that move at high speed, at a maximum output data rate of 400 Hz.

The RTK-enabled module also offers these features:

• Precise factory calibration of every production unit
• High immunity to magnetic interference
• Adaptive firmware operation to optimize performance in various types of scenario
• Easy-to-use, free MT Software Suite developer tools to accelerate integration into end-product designs
• Out-of-the-box operation with Xsens’ MTi development kits

“Centimeter-accurate positioning at an affordable price for commercial applications — this is the promise of the new RTK-compatible MTi-680G product,” said Boele de Bie, Xsens CEO. “From seed-sowing agricultural robots to autonomous cargo ships, a whole new generation of applications is now possible thanks to the centimeter-level accuracy of the MTi-680G’s position measurements.”

The MTi-680G is available for sampling now.
