LEO Successor to GNSS Comes Knocking

A group of Stanford Ph.D. and Masters graduates, with work experience among them at SpaceX, Ford Motor Systems, Blue Origin, Booz Allen Hamilton and other firms, has launched a start-up to start up a low-Earth orbit successor to GPS and other GNSS. The existing services, they say, are not up to the challenges of autonomy. They founded Xona Space Systems to supplant the venerable satnav systems.

Photonic Technology Brings a Cutting Edge to Inertial

Order-of-magnitude advances in inertial technology seem to take place roughly every 20 years, and the industry is poised at such a point now. New developments in photonic technology make high-performance inertial measurement accessible at lower size, weight and power. Many applications from driverless cars to UAVs can now take advantage of positioning that can independently bridge GPS outages from 2 minutes up to 10 minutes.

Receiver with Inertial for UAVs

A new GNSS/INS receiver, the AsteRx-i D UAS from Septentrio, specifically targets integration into unmanned aerial systems (UAS).  It provides centimeter-level RTK positioning and 3D attitude. It features a 44 pin connector compatible with 3rd-party integrations, as well as event marker inputs to accurately time-stamp camera shutter events.

Signal Vulnerability.

Previously, controlled reception pattern antennas (CRPAs) were only in the military domain, and highly classified. The need to counter increasing  GNSS signal jamming and spoofing in the civil realm has brought CRPAs into limited use there as well.  How to test for their efficacy in product design and development?

A free webinar on Wednesday, March 25 from 1:00 PM – 2:30 PM Eastern Daylight Savings Time addresses the topic “GNSS Vulnerability Testing and the Controlled Reception Pattern Antenna (CRPA).” This technically rich, educational event is sponsored by Spirent Communications and Inside GNSS.

Dual-frequency PPP GNSS and MEMS-IMU Integration For Continuous Navigation in Obstructed Environments

This article investigates and analyzes position solution availability and continuity from integrating low-cost, dual-frequency GNSS receivers using PPP processing with the latest low-cost, MEMS IMUs. The integration offers a complete, low-cost navigation solution that will enable during GNSS signal outages of half a minute, with a 30% improvement over low-cost, single-frequency GNSS-PPP with MEMS IMU integrations previously demonstrated. This can apply to UAVs, pedestrian navigation, autonomous vehicles, and more.
