Global Navigation Satellite Systems Engineering, Policy, and Design
MEMS has moved into the high-end market, and the latest disruptor to take into account is silicon MEMS. That’s micro-electromechanical systems based in silicon chips, for short. Accelerometers with up to 100g range and 70µg bias in a very small form factor — 6 cubic centimeters — are exploding the horizons for inertial applications.

The fourth GNSS Raw Measurements Task Force Workshop gathered more than 200 participants from 32 countries in an online experience in late May. A keynote presentation by Frank van Diggelen from Google led the charge, unveiling recently updated Google tools for logging and analyzing GNSS measurements on the Android platform. The European GNSS Agency (GSA) hosted.

A new magnetic anomaly navigation technique (MAGNAV), researched by the Air Force Institute of Technology (AFIT), will get its wings tested aboard F-16 fightercraft this September. In an effort seeking alternatives to GPS and GNSS, MAGNAV sensors and software will be flown on Air Force Test Pilots School (AFTPS) F-16s over a test range adjacent to Edwards Air Force Base in Nevada.

We cannot simply test-drive our way to safety. Instead, innovative methods of demonstrating safety and reliability must come into play immediately.
A free three-hour professional training over two days in June aims to show how.

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.
