CHC Navigation has released and is immediately shipping its new i90 IMU-RTK GNSS Series receiver. The i90 IMU-RTK GNSS Series is designed to dramatically increase GNSS real-time kinematic (RTK) availability and reliability.

The i90 is powered by the company’s latest inertial measurement unit (IMU) and RTK technology to provide robust and accurate GNSS positioning in any circumstances.

Unlike standard micro-electro-mechanical (MEMS)-based GNSS receivers, the i90 GNSS IMU-RTK combines a high-end calibration and interference-free IMU sensor with a state-of-the-art GNSS RTK engine and advanced GNSS tracking capabilities.

The i90 is designed to increase productivity and reliability of survey projects. No complicated calibration process, rotation, leveling or accessories are necessary with the i90 GNSS Series. Just a few meters’ walk will initialize the i90 internal IMU sensor and enable RTK survey in difficult field environments. The i90 GNSS automatic pole-tilt compensation boosts survey and stakeout speed by up to 20%.

“Our new i90 IMU-RTK GNSS Series is pushing the boundaries of conventional GNSS survey by extending RTK positioning availability and reliability,” said George Zhao, CEO of CHC Navigation. “CHCNAV is the GNSS technology enabler, making high-end GNSS solutions available for every surveyor.”

CEA-Leti and Orolia announce FlexFusion positioning and navigation technology

​Combining data from GNSS and IMUs ensures accuracy during GNSS outages.

Leti, a research institute of France’s CEA Tech, and Orolia have announced a new sensor-data-fusion engine that ensures resilient positioning and navigation even in cases of GNSS jamming or spoofing.

Orolia is a leader in accuracy and performance for terrestrial, aeronautic and naval transportation positioning, navigation and timing applications.

Called FlexFusion, the algorithm technology processes data from GNSS, inertial management units (IMU) and odometers to provide precise positioning in all conditions.

Orolia will present its latest technological developments at ION GNSS+, booth 311, taking place in Miami, Florida, Sept. 17-19.

FlexFusion’s design relies on a modelization of GNSS and IMU (triple-axis accelerometer, triple-axis gyrometer and triple-axis magnetometer) output for synthetic trajectory generation.

The fusion approach exploits Bayesian estimators, such as Kalman filters. The first algorithm was setup on modeling signals, and its optimization relies on an extensive real-life sample database acquired through field test. This process used CEA-Leti’s HYLOC reference platform, which provides a reference positioning of a few centimeters.

More than 100 trajectory samples were collected in urban, suburban, forest and mountain environments with different GNSS outage conditions.

The new positioning technology supports edge artificial intelligence (AI) because the data-fusion algorithm is performed locally to ensure that positioning and navigation information is available locally and is failsafe even in case of jamming or spoofing of GNSS data.

“Recent events have demonstrated that it is possible to change the course of a ship or force a drone to land in a hostile area by simply spoofing GPS signals,” said CEA-Leti CEO Emmanuel Sabonnadière. “The increasing reliance on a GNSS for the execution of military operations and terrestrial, aeronautic and naval transportation requires using positioning and navigation systems that are able to detect GNSS outages and provide resilient position and navigation features.”

A version of FlexFusion that demands less of the CPU implements a loose coupling algorithm that uses GNSS receiver-output positions as entry of the algorithm. An advanced version implements a tight coupling fusion algorithm of GNSS and IMU data that significantly enhances the resilience of positioning and navigation under real-world conditions.

This novel approach enables total control of treatments and filtering applied to raw signals, which increases performance of the fusion. It also improves positioning performance in particular if there are fewer than four GNSS satellites available, or when there are recurrent multi-trajectories, which sometimes occur in urban canyons.

CEA-Leti has licensed the patented FlexFusion algorithm to Orolia.

“Orolia is integrating FlexFusion in a new version of its VersaPNT product, the first compact, all-in-one and resilient positioning, navigation and timing (PNT) system for vehicles and blue force tracking, tactical UAV navigation and marine applications,” said Thierry Delhomme, EMEA general manager, Orolia. “This powerful algorithm helps deliver on the promise of VersaPNT as an always-accurate PNT system that operates in any environment.”

FlexFusion development was supported and partially funded by the Easytech program of IRT Nanoelec, thanks to the French National Program “Programme d’Investissement d’Avenir” ANR-10-AIRT-05.

U-blox GNSS modules help UAVs carry out life-saving work

The u-blox ZED-F9P, a high-precision GNSS module that delivers centimeter-level accuracy within seconds, has been incorporated into the latest electric Tron F90+ fixed-wing unmanned aerial vehicles (UAVs).

Quantum-Systems, a German company that specializes in electric VTOL (vertical take-off and landing) aircraft for civilian use, manufactures the Tron F90+, which is employed in mission-critical logistical activities such transporting emergency blood reserves to remote locations. Other uses include mining and agriculture-related tasks.

Quantum-Systems and u-blox are both exhibiting at Intergeo in Stuttgart, Germany, Sept. 17-20. Quantum-Systems is at booth K1.074, and u-blox at booth L1.025.

The Tron F90+ has a 3.5-meter wingspan and can travel at speeds of up to 160 km/hour with a 100-km flight range. It is the latest addition to the Quantum-Systems eVTOL UAV platform designed for cargo, inspection, survey and mapping, and reconnaissance in adverse conditions. Other models include the Trinity F9, Scorpion and Vector UAVs, all of which feature u-blox F9 high-precision GNSS technology.

In developing the Tron F90+ UAV, the Quantum-Systems engineering team needed accurate enough position data to ensure that VTOL operations would always go smoothly, and the valuable payloads were protected from damage.

Through the multi-band real-time kinematic (RTK) and raw code and carrier-phase data available to the ZED-F9P, the necessary positioning correction is assured and the pilot can complete even difficult maneuvers. Absolute position accuracy can be brought down to 3-5 centimeters.

Flirtey ready for drone deliveries to U.S. homes

Flirtey, a pioneer of the commercial drone delivery, has unveiled the Flirtey Eagle, along with a video of the next-generation delivery drone performing consumer and automated external defibrillator (AED) deliveries to homes.

Flirtey’s system is designed to safely get packages to customers with the delivery goal of less than 10 minutes using drones.

Along with the Flirtey Eagle, the aircraft designer and manufacturer unveiled the Flirtey Portal, a sophisticated takeoff and landing platform that enables scalable store-to-door operations. Also part of the system is an autonomous software platform that enables drones to deliver safely to American homes.

Flirtey said it is on course to conduct drone deliveries to U.S. homes as early as 2019.

Here are highlights of the UAV’s technology.

  • Flirtey’s aircraft is designed to operate in 95% of wind and weather conditions, making it highly reliable for flight.
  • The Flirtey Eagle is designed to fit 75% of packages that get delivered to its customers’ homes during last-mile deliveries.
  • The Flirtey Eagle safely and precisely delivers its contents by lowering a tether, while the drone is suspended in air, and once the package is delivered, it then retracts the tether.
  • Flirtey’s aircraft is controlled by its autonomous software platform, which has received Federal Aviation Administration (FAA) approval for the first multi-drone delivery operation in the United States, enabling a single remote pilot to simultaneously oversee ten Flirtey drones.
  • Flirtey’s Portal is a sophisticated takeoff and landing platform that fits into one parking space, making its infrastructure easily scalable to the company’s partners for store-to-door delivery.

Flirtey’s drone delivery technology has been developed from the ground up, originating from NASA’s drone program. Flirtey Founder and CEO Matthew Sweeny has brought together a team of aviation industry veterans from NASA, Raytheon, Lockheed Martin, and SpaceX, as well as military veterans from the army, navy, and air force.

“We expect Flirtey’s advanced drone delivery system will become the industry standard in America,” said Matthew Sweeny, Flirtey founder and CEO. “Flirtey’s latest technology makes life-saving and commercial drone delivery to homes in the United States an imminent reality.”

The Flirtey Eagle builds upon the advanced technologies developed for Flirtey’s previous generation aircraft that conducted the first Federal Aviation Administration (FAA)-approved drone delivery in the United States, which is going on display alongside the Wright Flyer in the Smithsonian National Air and Space Museum in Washington, D.C. Flirtey’s goal is to not only meet, but to surpass the rigorous safety standards of the FAA. Flirtey’s regulatory approvals include:

  • Approval to conduct multi-drone delivery operations, enabling a single remote pilot to simultaneously oversee 10 Flirtey drones
  • Approval to conduct drone delivery flights beyond visual line of sight (BVLOS), enabling Flirtey to conduct drone delivery operations with a pilot controlling the flights from a remote location
  • Approval to conduct drone delivery flights at night, making drone delivery accessible at any time

Flirtey and the City of Reno were chosen for the FAA and Department of Transportation’s Unmanned Aircraft System (UAS) Integration Pilot Program (IPP). Within the IPP, Flirtey and the City of Reno have partnered with REMSA, local emergency medical services provider, to deliver AEDs to those in need. Flirtey’s AED delivery technology has the potential to save 150,000 lives per year, the company said.

Based on demand from customers, Flirtey expects demand initially to outstrip supply. Flirtey’s drone delivery system was designed from the outset to meet the anticipated high demand.
