摘要

"PSEUDOLITE, RECEIVER, N-CHANNEL GPS RECEIVER BANK AND ATTACHED FREQUENCY CONVERTERS AND COMPUTER PROCESS TO DETERMINE ALL CARRIER PHASE AMBIGUITIES FOR EACH RECEIVED PSEUDOLIT SIGNAL". Apparatus and method for resolving integrity ambiguities in position determination. One embodiment of the invention includes a reference system, augmented with multiple frequency pseudoliths using a carrier phase differential GPS implementation, and a mobile system. In one embodiment, the reference system components include one or more multi-frequency pseudoliths, one or more multi-frequency reference receivers, a separate or constructed data link in the pseudoliths, and the antennas associated with each of these elements. . Reference system components may be stationary. The mobile system may include a multi-frequency receiver and its associated antennas. Because the mobile system can passively receive information, an unlimited number of mobile systems may be included in any given embodiment of the invention. A multi-frequency pseudolith uses a single frequency source to synthesize all multiple carrier frequencies and all modulated baseband signals over carrier frequencies for transmission.
