ABSTRACT OF THE DISCLOSURE "MICROCOMPUTER-CONTROLLED PORTABLE SATELLITE SIGNAL SIMULATOR FOR EXPLORATION SYSTEMS, AND METHOD OF USE" In accordance with the invention, satellite navigation receiver system of an exploration system for exploring for hydrocarbons in earth formations can be tested for fieldworthiness using a portable microcomputer- controlled satellite navigation simulator. From encoded inputs of local latitude, longitude, Greenwich mean time and antenna height, both array data parameters and real- time control signals are generated for simulating signals of an orbiting TRANSIT navigation satellite vis-a-vis the satellite navigation receiver system. To such system the received signals are indistinguishable from conventional TRANSIT satellite navigation signals. Result: by merely cross-checking simulator "turn-key" encoded data with the final computed fix, a technologist (who need not be a programming expert) can determine the fieldworthiness of the satellite navigation receiver system.
