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.

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.

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.

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.

One may well ask, when doesn’t it?
That aside, some controversy has arisen in the world of competitive running, and self-competitive running as in Personal Bests, or PBs. Runners find their fitness trackers and watches don’t necessarily tell them the truth in terms of distance travelled. In fact, they very rarely tell the absolute truth. Which matters.
