An ancient mapping technique may offer a reliable backup tool for UAVs.

Researchers have developed a vision-based navigation system that uses visual data from stars. The system developed by engineers at the University of South Australia (UniSA) offers a reliable alternative for nighttime navigation in areas where GPS signals are inaccessible or unreliable.

A surge in GPS jamming attacks in drone warfare has inspired Australian researchers to develop a celestial navigation system that uses visual data from stars rather than relying on the global positioning system.
