NASA satellites ace world's 1st 'lost-in-space' GPS-free navigation experiment

NASA’s satellite mission has achieved a groundbreaking milestone, demonstrating successful navigation without relying on traditional Global Positioning System (GPS) technology. The project utilized onboard sensors and algorithms to determine the spacecraft’s position and orientation within its orbit. This marks the first time such a prolonged, GPS-free navigation experiment has been conducted using multiple satellites simultaneously. Data collected during the test will be crucial for future deep-space missions where reliance on external positioning systems is limited or unavailable. Scientists anticipate this success will significantly advance autonomous navigation capabilities for robotic explorers venturing further into our solar system.
