Global Navigation Satellite Systems Engineering, Policy, and Design
GNSS jamming trials are being carried out on the Island of Andøya, in Northwestern Norway, during Jammertest 2024. The event features both simple and sophisticated, staged spoofing and jamming attacks, allowing participants to identify potential strengths and weaknesses in their GNSS-based systems.

Ariane 6’s inaugural rocket launch took place from Europe’s Spaceport in French Guiana at 16:00 local time on 9 July. It has taken over from Ariane 5, featuring a modular design that can launch missions from low-Earth orbit and into deep space. Galileo Second Generation (G2) satellites are projected to join the constellation in 2026 with the Ariane 6 launcher. G2 satellites will use electric propulsion and host a more powerful navigation antenna, better atomic clocks and fully digital payloads.
