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.
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.

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.
