Geospatial 3D mapping specialist GeoSLAM provided the technology to scan one of Europe’s largest caves as a part of the Deep Time isolation study.

For 40 days, 15 participants set up camp in the Lombrives cave in southwestern France with no clocks or sunlight, and zero contact with the outside world. Conducted by the Human Adaptation Institute, the experiment aimed to explore the links between the human brain and time, in order to gain insight into the limits of human adaptability to isolation.

Throughout the mission, the “deeptimers” organized tasks to complete within the cave setting to help structure their days. Their first task was to conduct a recce of the location.

GeoSLAM technology was called upon to conduct a digital scan of the 3-km Lombrives cave — a cave system consisting of both narrow passages and expansive chambers up to 70 meters in height, formed more than 125 million years ago.

The team used the lightweight ZEB Horizon device, which harnesses GeoSLAM’s unique SLAM (simultaneous localization and mapping) algorithm, putting to the test the device’s 100-m range capabilities. Its versatility and walk-and-scan method of data collection allowed the team the flexibility to crouch, crawl and scan the depths and narrow canals of the cave, including 90-m deep wells.

Traditional tripod-based systems used for digital mapping rely heavily on GPS to collect accurate data. SLAM technology however, overcomes this limitation by cutting out GPS altogether, enabling scans to be carried out in complex and enclosed spaces, including underground.

With low light levels, an ambient temperature of 10 degrees and humidity levels of 100 percent, the physical and psychological impacts the team experienced were documented on camera.

“We are thrilled to have been associated with the Human Adaption Institute on such an exciting and historic project,” said Tomas Blaha, GeoSLAM channel manager for Europe. “The handheld capabilities of the ZEB Horizon device provided easy-to-use technology for the members of the team with no professional surveying experience. The study tested the limits of human endurance in a challenging environment, and the same can be said of the technology to survey the Lombrives cave. Using traditional static and GPS-based scanners would have been impossible for this project, so we are delighted that the ZEB Horizon’s adaptability and ruggedness played its part in an historic piece of research.”

Earth Archive project aims to create digital twin of entire planet

Earth Archive event

The Earth Archive Initiative is an unprecedented scientific effort to create a digital twin of the entire surface of the Earth – and everything on it.

By scanning the planet’s land surface with very high-resolution lidar, the Earth Archive will create a true three-dimensional digital twin of our world — an open source, digital record of the Earth that will reflect the landscape exactly as it was at the time of scanning.

The geospatial data captured will serve as the baseline for understanding and exploring our world.

A virtual conference, billed as the “Chapter I : The Amazon,” takes place June 15-16, and will provide updates on the unique project from academics, non-government organizations, technology providers and the public. Registration is free.

The Amazon Basin is the first region chosen for scanning and the focus of the conference. “While our scope is the entire planet, we’ve tasked ourselves with first scanning areas that are not only most susceptible to change, but also deep in value for understanding our past,” a project spokesperson explained.

“The 2021 inaugural Earth Archive Congress is centered on our initial campaign to scan the entire Amazon Basin. The Amazon rainforest plays a monumental role in the Earth’s climate, has an incredibly rich Indigenous history, and boasts a remarkable level of ecological diversity — but is vanishing before our eyes.

“With the ability to digitally preserve landscapes at any moment in time, very high resolution lidar can enhance archaeological, anthropological, and conservation studies and provide needed information to help advance sustainable development, as well as provide us with more groundbreaking revelations of the Amazon’s astounding past.”

Registration at the Earth Archive Virtual Congress is complimentary.

UAV Navigation provides flight-control solution for VTOL platforms

UAV Navigation has developed a flight-control solution specifically for vertical-take-off-and-landing (VTOL) fixed-wing drones.

Interest in using VTOL platforms has grown in the past few years, according to the company. A hybrid between fixed-wing and rotary-wing platforms, VTOLs provide operators with versatility.

The company’s fixed- and rotary-wing development teams worked together on the flight-control solution. Technological capabilities from other solutions — referenced navigation or the development of missions in environments without GNSS signals and under threat of jamming attack — have been incorporated in an organic way to facilitate a complete and reliable system.

The hardware developed by UAV Navigation has the MIL-STD-810F and MIL-STD 461F certification, proving the system has been tested by an independent body that certifies its extraordinary behavior in adverse conditions.

“Our extensive experience with fixed-wing and rotary-wing platforms allows us to know the strengths and challenges that these platforms face as a mission is performed,” said Miguel Ángel de Frutos, CTO of UAV Navigation. “Taking this as a starting point, we have managed to develop a specific solution for VTOL platforms that not only has the same technological capabilities as our existing solutions, but also enables missions to be carried out with the highest possible security.”

One of the main challenges with VTOL platforms is the transition from vertical to horizontal flight and vice versa. UAV Navigation’s solution facilitates and automates this critical moment as much as possible, while optimizing battery use. A series of safety and emergency procedures allow the aircraft to always reach a safe landing zone and overcome possible errors in the engine.

An adaptable VTOL software architecture allows users to customize and configure the solution through the ground control station.

Partnership with AnsuR Technologies

logosUAV Navigation is partnering with AnsuR Technologies to enable streaming high-definition (HD) video from small UAVs carrying a 200-kbps satcom terminal.

With the partnership, the Asmira software solution fro AnsuR provides the ability to optimize sending video and images for satellite communications. Asmira, together with the Cobham Aviator UAV 200 and the antenna pointing solution Polar-300, provided by UAV Navigation, can deliver cost-effective high quality video transmission for small satellite platforms.

Integrated into the platform’s onboard network, UAV Navigation’s Polar AHRS delivers the attitude and steering information of the platform so the Cobham device can establish contact with the satellite.

The Polar AHRS, a device designed to meet the demanding needs of the aeronautical sector, includes all the necessary sensors in a compact device to provide precise information to the servos in a gimbal or an antenna, enabling its control. Once a stable satellite link is established, the Asmira software delivers HD-quality video at rates down to 100 kbps and can support SD quality below 50kbps.

The partnership enables good-quality streaming for long-range surveillance, infrastructure monitoring and search-and-rescue missions where videos are critical.

Photo: Per Vices

Per Vices Corp. has launched an upgraded version of its high-performance software-defined radio (SDR) platform Cyan EC (extended channel).

Cyan EC enables up to 64 digital signal processing (DSP) channels across 16 physical SMA ports. This extension allows Cyan EC users to break up the one large bandwidth physical chain into multiple digital channels, allowing the radio platform to do the multiplexing.

By providing additional digital chains, which are coherently superimposed into a single physical channel, the computational complexity required to address wide bandwidths is further reduced, and allows for processing over multiple cores on a single host system or across multiple host systems concurrently.

“We are excited that customers have already used and integrated our platform into their products,” said Victor Wollesen, CEO of Per Vices Corp “The additional processing capability provided by this option allows our customers to improve performance and implement more advanced applications using existing computational resources. I believe Cyan EC is the highest channel count software-defined radio commercially available.”

The Cyan EC product option enables engineers and system integrators to realize the benefits of both the high-bandwidth SDR and having more independent channels to ease the complexity associated with processing the high amount of data by breaking it up into separate channels. This further helps to achieve better spurious-free dynamic range (SFDR), sensitivity and signal-to-noise ratio (SNR) while continuing to offer a high throughput SDR solution.

Cyan EC benefits engineers and integrators across different markets including GNSS/GPS, radar systems, magnetic resonance imaging (MRI) receivers and exciters, and spectrum monitoring, as well as test and measurement.

Drones buzz warships

Several drones swarmed Navy destroyers off the California coast in July 2019, and it remains unclear who was behind the nighttime flights, according to a report on the website The Drive, quoting ship logs. As many as six drones flew around the warships at a time in often low-visibility conditions over a number of days, with the drones flashing lights and prompting security precautions onboard. The drone flights took place near San Clemente Island, home to sensitive military facilities: a Navy SEAL training site, the Navy’s ship-to-shore live firing range and an airfield. The drone flights prompted inquiries from investigators and intelligence officers in the Navy and the FBI, and are receiving high-level attention.


Blast shakes ionosphere

A 2020 explosion in Beirut, Lebanon, caused a southward-bound, high-velocity atmospheric wave that rivaled ones generated by volcanic eruptions, according to researchers at Hokkaido University in Japan. On Aug. 4, 2020, more than 2,750 tons of unsafely stored ammonium nitrate exploded, killing 200 people and leaving a 140-meter-diameter crater in its wake. To estimate variation in total electron content, the researchers collected RINEX GNSS data from 15 CORS stations in Israel and Palestine. The ionospheric disturbance was detected by differential delays of microwave signals of two carrier frequencies from GNSS satellites. The blast is considered one of the most powerful non-nuclear, manmade explosions in human history. Their findings are published in the Feb. 2, 2021, issue of Scientific Reports.

New GAJT-410MS provides anti-jamming in marine environments

Photo: pierivb/iStock / Getty Images Plus/Getty Images

Photo: pierivb/iStock/Getty Images Plus/Getty Images

Hexagon | NovAtel has released the GAJT-410MS in response to the increase of interference and jamming in marine environments worldwide. The GAJT-410MS is the company’s latest addition to its proven GPS Anti-Jam Technology (GAJT) for the commercial and defense marine markets.

The low size, weight and power (SWaP) variant protects civil and military operations from interference and jamming, with jammer direction-finding capabilities for enhanced situational awareness in the marine environment.

The GAJT-410MS provides dynamic protection on both GPS L1 and L2 bands, as well as Galileo E1, QZSS L1 and L2 and SBAS L1 to combat intentional and unintentional interference. If a vessel experiences jamming, the device’s direction-finding capabilities provide improved situation awareness of their RF environment to identify and locate the source of the jamming signals.

The commercial off-the-shelf, non-ITAR solution is easy to install or retrofit onto existing fleets, enabling assured PNT for continuous operations, cybersecurity and safe navigation at sea, NovAtel said.

Interference, both benign and malicious, is a challenge facing civilian and military operations. Commercial marine applications like shipping, tankers and bulk carriers are under threat from interference targeting their navigation and cybersecurity. Without assured positioning, these vessels can drift off-course and place the vessel, crew and cargo at risk.

Nearshore marine applications like survey, construction and piloting also require reliable positioning for uninterrupted operations in crowded waterways and RF environments. Interference mitigation and jammer direction-finding for advanced situation awareness ensure users acquire assured positioning, navigating and timing (PNT) while identifying and limiting risk from interference sources.

“Assured navigation and cybersecurity defenses are growing priorities for marine users as global threats from interference and jamming increase,” said David Russell, marine segment portfolio manager for Hexagon’s Autonomy & Positioning division. “The GAJT-410MS is an anti-jam solution protecting vessels from interference and jamming disruptions to ensure continuous operations wherever your application takes you. With GAJT, your position, navigation and timing are protected and assured.”

The GAJT-410MS is the latest iteration of proven, high-performance anti-jam products from NovAtel. It includes flexible mounting options, jammer presence and direction-finding capabilities for advanced situation awareness.

Photo: uAvionix

uAvionix has added a new low-SWaP transponder to its line-up of unmanned aerial system (UAS) communications, navigation and surveillance solutions.

The ping200XR integrates the capability of the ping200X TSO Certified Mode S ADS-B OUT transponder with the high-integrity truFYX TSO-certified GPS position source into a single enclosure. The single enclosure simplifies installation and allows the customer to choose between the existing installed GPS antenna or one provided with the ping200XR.

The integrated GPS ensures maximum safety by providing Source Integrity Level (SIL) 3 RTCA DO-229D and TSO-C145e Class Beta 1 performance, a requirement for Mode S and ADS-B airspace access, and for reception and processing by certified avionics and Traffic Collision Avoidance Systems (TCAS) in other aircraft, as well as Air Traffic Control (ATC). SIL 3 performance is not available from non-aviation certified GPS, which are often used as an autopilot navigation source.

The ping200XR can be integrated with popular onboard UAS autopilots for dynamic control from ground-control stations, including George — uAvionix’s enterprise autopilot solution. The ping200XR can also be pre-configured before flight and carried as a payload.

Replicating the functionality of a cockpit transponder controller, the uAvionix mini-controller allows users to dial-in a squawk code before takeoff for even quicker integration and rapid deployment.
