New Technology to Protect GPS Signals for UAVs Demo’d at AUVSI

Honeywell and InfiniDome are collaborating on a GPS signal-protection programs and showcasing a preliminary model of their joint answer on the AUVSI Xponential Show in Atlanta, Aug. 16-19. The mixed {hardware}, software program and companies providing is designed to deal with sign disruptions and keep entry to vital navigation and timing info.

The options are meant to serve a wide range of functions for each protection and industrial functions, significantly city air mobility programs, unmanned aerial programs and floor autos. As extra small autos take to the skies and roads in closely populated areas, GPS sign availability should be maintained to supply correct navigation, guarantee security and defend property.

The joint answer is designed to seamlessly deal with loss or lack of GPS indicators, lowering the probability of collisions and detour. The corporations state this can even permit clients to extend payloads and reduce mission occasions with the omission of the costly sensors at present employed to deal with GPS interference.

Earlier this yr, Infinidome demonstrated increased GNSS resiliency to hostile jamming in unmanned plane programs (UAS) flight trials sponsored by the Israeli authorities, in response to the corporate. The drone’s GPS receiver overcame GPS jamming situations utilizing infiniDome’s GPSdome safety, which locked on and maintained the GNSS indicators all through the checks. The firm’s GPSdome anti-jamming answer is a small, add-on module that makes use of two off-the-shelf antennas and interfaces to the GNSS receiver on the RF stage. A phased-array  filtering algorithm combines patterns from two omni-directional antennas in real-time to create a brand new sample which attenuates the sturdy jamming sign, exactly concentrating on a null within the path of the attacking indicators.

The know-how can even help public security for rapidly evolving low-altitude functions comparable to cargo drones and concrete air transportation autos. The preliminary answer providing is predicted to be commercially accessible within the first half of 2022.

“We’re working to develop a first-of-its-kind holistic answer constructed on tightly built-in layers of safety for all makes use of of navigation for unmanned air and floor autos,” mentioned Omer Sharar, CEO, InfiniDome.
