In today’s contested battlespaces, Global Navigation Satellite System (GNSS) signals can be jammed, spoofed, or vanish entirely, leaving aircraft blind and vulnerable.French company Sodern has developed a workaround: the “Astradia” system that looks to the stars instead of satellites to keep aircraft and drones on course amid electronic warfare.Because the system emits no signals of its own, it reduces the risk of detection, making it a potentially useful tool for stealth operations.Read the full story on our new publication, NextGen Defense: Sodern’s New Tech Uses Stars, Not Satellites, to Guide Aircraft in GPS-Denied ZonesThe post Sodern’s New Tech Uses Stars to Guide Aircraft When GPS Fails appeared first on The Defense Post.
