A RECEIVER AND TRANSMITTER FOR USE IN A SATELLITE NAVIGATION SYSTEM |
摘要 |
A receiver is provided for use with a satellite navigation system comprising a constellation of multiple satellites. Each satellite transmits a signal incorporating a spreading code. The receiver includes at least one code storage unit that includes combinatorial logic for storing a memory code comprising a fixed pattern of bits including address decoding, wherein the stored memory code corresponds to a spreading code incorporated into a signal transmitted from a satellite. The receiver further includes a correlator for performing a correlation between an incoming signal and the stored spreading code from the one code storage unit. |
