Researchers at The Ohio State University and the University of California, Irvine have come up with a method for locating a position on Earth using signals broadcast by SpaceX's Starlink Internet service satellites.

Signals from six Starlink satellites were used to identify a location on Earth within 8 meters, suggesting the method could serve as an alternative to GPS.

Ohio State's Zak Kassas said, "We eavesdropped on the signal, and then we designed sophisticated algorithms to pinpoint our location, and we showed that it works with great accuracy. And even though Starlink wasn't designed for navigation purposes, we showed that it was possible to learn parts of the system well enough to use it for navigation."
