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.
