Abstract
A method and system for determining the geolocation of a vehicle in the absence of a GPS signal includes determining the geodetic position of each of a plurality of airborne objects based on the relative position of at least one star and at least one satellite. The determined geodetic positions of each of the airborne objects is transmitted to the vehicle. A distance from the vehicle to each airborne vehicle is calculated. Based on the geodetic position determined for each airborne object and the distance from the vehicle to each of the airborne objects, the geodetic position of the vehicle is determined. A receiver receives the geodetic position of each airborne object, calculates a distance to each airborne object, and determines a current geodetic position based on the received geodetic positions of the airborne objects and the distance from the vehicle to each airborne object.
