In one implementation, a pair of messages are received from one or more space-based receivers that each received the pair of messages. The pair of messages comprise encoded position information of a transmitter, and a plurality of candidate locations for the transmitter is determined therefrom. A location of the transmitter is determined by eliminating candidate locations until only one remains. In particular, each candidate location that is not within a coverage area of each of the space-based receivers is eliminated, and each candidate location that is not within a predetermined distance of at least one previous candidate location is eliminated. In addition, it is determined that the remaining candidate location is within the coverage area of each of the space-based receivers as well as within the predetermined distance of at least one previous candidate location. Upon determining the location of the transmitter, it is transmitted to a subscriber system.
