Global Navigation Satellite Systems Engineering, Policy, and Design
Physical Logic of Petah Tikva, Israel received a customer contract for $2 million for continuing development of a new-generation navigation-grade closed-loop micro-electromechanical (MEMS) accelerometer, the MAXL-CL-4000.

A European consortium led by the French map service provider GEOSAT will investigate how the combination of self-driving mapping cars — or autonomous mobile mapping systems (AMMS) — and artificial intelligence-based mapping software can automate the production of high-definition (HD) maps.

The joint exploitation of meta-signals received from multiple GNSS satellites, and from one or multiple antennas, can achieve high-accuracy PNT solutions in harsh propagation conditions.
A new methodology targets sub-meter GNSS accuracies in the consumer realm for applications such as augmented reality and visually impaired navigation. Recent Android RTK smartphone services in a real-time environment achieve accuracies below 50 cm. Can these be matched with PPP?

Galileo Through the Lenses of Money, Defense, Brexit and Unfortunate Events
The year of our European correspondent generally begins with two predictive events: the ESA New Year press breakfast in Paris and the EU Space Policy Conference in Brussels. It’s a tough job but somebody’s got to do it.

After years of delay, we see movement toward a back-up service for PNT and ensuring that critical infrastructure owners and operators take steps to limit vulnerabilities.

Three different low-cost sensor integrations, covering vehicle navigation in a range of environments, were explored and explained in the February webinar, “Automotive-Grade GNSS + Inertial for Robust Navigation.” The full webinar, slides and audio, is available for download now.
Knowledge gained in close study of post-processed GNSS/INS data from very high-dynamic aerial maneuvers can improve position monitoring in machine control, precision agriculture and other industrial applications.
Hours before an impending government shutdown, the President signed both the defense appropriations and authorization bills on December 20. The bills funded nearly all of the Air Force’s GPS program but made substantial cuts in Army GPS receiver development.

GNSS jamming and spoofing continue to draw keen audience interest at the hottest, coolest and even the most obscure tech, trade and public policy conferences. Speakers can now recount any number of real-world spoofing incidents where GNSS users have been fooled by tech wunderkind, unwitting technology demonstrators and even enemy regimes.
