LEO internet satellites bolster navigation where GPS is weak

As intentional and unintentional interference with GPS grows worldwide, researchers have shown that radio signals from commercial low Earth orbit (LEO) internet constellations such as Starlink and OneWeb can provide an alternative source of navigation and positioning, especially in regions where GNSS performance is degraded. The new work indicates that passively received LEO signals can be turned into useful navigation beacons without modifying the satellites or accessing user data.

Many sectors, including transportation, telecommunications, finance and critical infrastructure, rely on Global Navigation Satellite Systems (GNSS) like GPS for positioning, navigation and timing, but these signals are weak at the surface and vulner
