Satellites Navigate Without GPS | Science News
NASA’s cracked the code on GPS-free satellite navigation using FALCON, a brainy system that lets spacecraft pinpoint their location by spotting other satellites and space junk—like cosmic landmarks. Tested in real missions like Starling, FALCON autonomously tracked over 200 objects in just three days, slashing reliance on Earth-based signals. This tech isn’t just sci-fi—it’s revolutionizing space traffic control, enabling smarter scientific missions, and even turning into a commercial product, proving how lab research can rocket into real-world space operations.
