Abstract
Determining the location of a device communicating an emergency call to an emergency call center via an orbital base station, wherein the device is located outside of a terrestrial network coverage region, can comprise determining a Doppler shift from a signal received from the device, determining a signal time delay of the signal received from the device, determining a location of the orbital base station, and computing a geolocation of the device based on the Doppler shift, the signal time delay, and the location of the orbital base station.
