ABSTRACT:
A method for testing GPS receivers may read GPS files with data for a plurality of GPS satellites, and two or more GPS satellites may be selected from that data. The method may receive parameters for a GPS receiver to be tested. The method may generate two or more GPS signals for the two or more selected GPS satellites. The method may operate on the two or more GPS signals using the received parameters for the GPS receiver to generate two or more calculated GPS signals. These two or more calculated GPS signals may be re-sampled to a common rate. The two or more re-sampled GPS signals may be added together to create a composite GPS signal. The composite GPS signal may be generated using a hardware signal generator, where the composite GPS signal used to test the GPS receiver.
