Galileo Tests Encrypted Anti-Spoofing Signal
2 min read
The European Space Agency achieved its first cryptographically secured position fix under spoofing conditions using Galileo satellites at Norway's Jammertest event. Galileo's Signal Authentication System encrypts spreading codes, letting receivers verify signals against false ones. The week-long test used five satellites, and the method could extend to other GNSS systems like GPS, which currently lack verification measures.
