Claim Text:
1. A method for determining the geolocation of a vehicle, the method comprising: determining at each of a plurality of airborne objects, and independently of a satellite transmission signal, a geodetic position for each of said plurality of airborne objects based on a relative position of at least one star and at least one satellite, wherein determining the geodetic position of each airborne object comprises the steps of: transmitting from each of said plurality of airborne objects said determined geodetic positions to said vehicle over a non-satellite based navigation communications link; calculating a distance from said vehicle to each of said plurality of airborne vehicles based on data received by said vehicle over said non-satellite based navigation communications link; and determining by a processor, a current geodetic position of said vehicle based on said determined geodetic positions of said plurality of airborne objects and said calculated distances from said vehicle to each of said airborne objects.
