According to a non-peer-reviewed paper, Humphreys and Peter Iannucci of the Radionavigation Laboratory state they have determined the Starlink satellites operating in low Earth orbit could provide an 'unjammable' alternative to Global Navigation Services, GPS. "Anticipation is building for commercial broadband Internet services provided by mega-constellations of satellites in low Earth orbit. Such services’ global reach, low latency, and wide bandwith situate them to revolutionize broadband communications. This paper seeks to establish a less-obvious assertion: In addition to broadband service, these constellations could revolutionize satellite-based positioning, navigation, and timing," the paper reads. "Their space vehicles are far nearer and more numerous than those of traditional global navigation satellite systems in medium Earth orbit or geostationary orbit, and their communications transponders have both exceedingly high gain and access to a vast allocation of spectrum."

The paper describes in great technical detail, a system that utilizes the Starlink satellites working alongside traditional GPS signals to deliver precise location signals more accurate and faster than current GPS.
