Global Navigation Satellite Systems Engineering, Policy, and Design
Three different low-cost sensor integrations, covering vehicle navigation in a range of environments, will be covered in a February 12 webinar, “Automotive-Grade GNSS + Inertial for Robust Navigation.”
European Space Agency (ESA) top brass welcomed journalists to the Agency’s headquarters in Paris for its annual New Year’s press launch. On hand was the Director General as well as ESA’s Galileo guru Paul Verhoef, who spoke one-on-one with Inside GNSS.

The chairman of the Federal Communications Commission (FCC) told two U.S. Senators in January that his agency could not complete a decision on Ligado Network’s license modification by the end of 2019 because of a late-in-the-year response from a key federal agency.

In the years since civil and commercial use of GPS and GNSS became common in the mid-1990s, a variety of software tools have been developed to perform offline analyses of GNSS performance and data collected from GNSS receivers. Some of these tools are part of commercial software packages such as Matlab [1] or STK [2]. This article focuses on tools that are freely available (as of early 2020) and are standalone or work with commercial software.

Despite a surge of activity at the end of the year, the FCC has not yet ruled on a request by Ligado Networks to use its spectrum for a terrestrial network. It is unclear what will inspire federal regulators to finally decide.
I strode into the plenary session of the ION International Technical Meeting, primed and ready for a barrage of modernity, of out-in-front advances in precision positioning, navigation and timing. The first thing I saw was a 7-foot tall cesium beam tube, an early atomic clock from the 1950s.
