NASA tests navigation system that lets satellites find position without GPS
NASA has successfully tested the FALCON navigation system, which allows satellites to determine their position in space using nearby objects rather than relying on GPS. This technology is designed to improve autonomy for deep-space missions where traditional GPS signals are unavailable or unreliable.
Why it matters
Autonomous navigation is critical for the future of space exploration, enabling spacecraft to operate independently in deep space and around the Moon without constant ground-based or GPS support.
NASA has tested a navigation system that allows satellites to determine their position without relying on GPS. Instead of depending on an external navigation network, the system uses other spacecraft and orbital debris as reference points to work out where a satellite is in space.The technology, called FALCON, was tested as part of NASA’s Starling mission. FALCON stands for Fast Autonomous Lost-in-space Catalog-based Optical Navigation. According to Science Daily, during the demonstration, the system not only helped a spacecraft determine its own orbit but also improved the estimated orbits of more than 200 other space objects in just three days.The test is aimed at making spacecraft more independent. GPS signals that satellites use near Earth can become weak, unreliable or unavailable around the Moon and in deep space.
