<ul><li>Researchers at the University of South Australia have developed a low-cost prototype system that allows drones to navigate using celestial triangulation and vision-based algorithmic computing.</li><li>The system does not emit any signals, making it resistant to GPS jamming attacks.</li><li>The prototype consists of a Raspberry Pi 5 computer and a monochrome sensor with a wide-angle lens, connected to a drone's autonomous piloting system.</li><li>Although not as precise as GPS, the system provides a backup for navigation in case of GPS failure and could be useful in combat, surveillance, and remote environmental monitoring missions.</li></ul>
