Global Navigation Satellite Systems Engineering, Policy, and Design
The Institute of Navigation (ION) announced that its annual ION GNSS+ 2020 conference, scheduled to take place September 21-25, will now be held entirely virtual. InterGeo, the large international trade show held each fall in Germany, has made a similar announcement for its conference, scheduled for October 13–15.

Britain has signed a £900 million ($1.135 billion) deal to buy a part share of satellite operator OneWeb, a low-Earth orbit constellation in-the-making, designed to provide global high-speed broadband services. There had been speculation that the government intended thereby to generate its own satellite-based navigation signals, as it has been shut out of Galileo security signals by its Brexit move. Some satnav experts quickly dashed that notion, but others demonstrated that it just may be possible.

Silicon Sensing Systems’ high performance DMU30 micro electro-mechanical systems (MEMS) inertial measurement unit (IMU) has been selected by the Institute for Q-shu Pioneers of Space, Inc. (iQPS) of Fukuoka, Japan, for the control system of Japan’s first X-band synthetic aperture radar (SAR) small satellite.

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.
