Starlink's satellites can be updated to provide navigation which is more accurate and less prone to interference than GPS.

The findings have been published in a non-peer-reviewed paper on preprint repository arXiv by Todd Humphreys and Peter Iannucci at the Radionavigation Laboratory at The University of Texas.

Humphreys and Iannucci propose a new system that harnesses Starlink's rapidly-growing constellation of satellites to provide “far more robust”...
