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.

2017 and 2018 saw unprecedented GNSS interference activity, from the eastern Mediterranean to Norway and Finland. Syria emerged as a testbed for electronic warfare capabilities. In April 2018, General Raymond Thomas, commander, U.S. Special Operations Command, referred to the region as “the most aggressive electronic warfare environment on the planet.”

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.
A new cloud-based, digital reality visualization platform in the Hexagon AB booth turned heads at the Consumer Electronics (CES) megashow in Las Vegas in early January. HxDR creates accurate digital representations of the real world through the seamless combination of reality-capture data from airborne, ground and mobile sensors.

This article investigates and analyzes position solution availability and continuity from integrating low-cost, dual-frequency GNSS receivers using PPP processing with the latest low-cost, MEMS IMUs. The integration offers a complete, low-cost navigation solution that will enable during GNSS signal outages of half a minute, with a 30% improvement over low-cost, single-frequency GNSS-PPP with MEMS IMU integrations previously demonstrated. This can apply to UAVs, pedestrian navigation, autonomous vehicles, and more.
