US Patent 11237277 Techniques for determining geolocations

The described geolocation techniques determine a location of an earth-based vehicle using a non-geostationary satellite. For instance, the non-geostationary satellite receives signals transmitted by the earth-based vehicle, determines the arrival times of the signals, and the position information of the satellite corresponding to the arrival times of the signals. The arrival times and position information of the satellite are sent to a signal processing unit to determine a location of the vehicle.
