Characterizing GNSS Interference from Low-Earth Orbit

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.”

Dual-frequency PPP GNSS and MEMS-IMU Integration For Continuous Navigation in Obstructed Environments

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.
