Global Navigation Satellite Systems Engineering, Policy, and Design
Testing of the first Galileo Second Generation (G2) hardware has begun, with versions of the satellites’ navigation payloads and antennas undergoing evaluation to check whether they meet the ambitious performance levels set for the coming generation of Europe’s GNSS.

Interference mitigation techniques should protect GNSS receivers from interference and jamming without biasing their final position, velocity and timing solution. This column analyses five popular interference mitigation techniques, including the Adaptive Notch Filter (ANF) and Pulse Blanking (PB), evaluating their impact on pseudoranges and on the final position and timing solution. Several GNSS modulations are considered, showing the advantage of using GNSS signals with similar spectral characteristics.
The European Commission and the European Space Agency (ESA) selected Leonardo’s hydrogen atomic clocks for Galileo Second Generation.

The French company Geoflex demonstrated GNSS corrections-driven centimetric positioning in Brazzaville, Republic of Congo on July 8, at the national Stadium Alphonse Massamba-Debat. The demo employed a dual-frequency GNSS chipset receiving GPS and Galileo signals and the Geoflex corrections service via the Nigerian NIGCOMSAT-1R satellite on L Band

For autonomous transport to become a reality, its operations must be at least as safe as existing ones. The European Commission’s Directorate-General for Defence Industry and Space (DG-DEFIS) has awarded mission evolution studies to assess how the future evolution of European GNSS (EGNSS) could be beneficial for innovative and demanding autonomous applications.
