1. A method for an application on a mobile device to automatically send a mobile device location of the mobile device to a terrestrial network via an SOS call, the method comprising:
determining the mobile device location, using Doppler shift and signal time delay measurements from an orbital base station and corresponding compensation; and
in response to a terrestrial network determining that geolocation information available to the terrestrial network has a reliability below a predetermined reliability threshold, sending a GPS location to an emergency call center from the mobile device.
