HIGH-SPEED, HIGH-SENSITIVITY GPS RECEIVER

摘要

PROBLEM TO BE SOLVED: To obtaine and track global positioning system signals with a fast acquisition speed and high sensitivity.;SOLUTION: A filter operation for matching pseudo-random noise is performed on a sample of the global positioning system signals to provide a current matched filter result. The current matched filter result is then accumulated with prior matched filter results obtained from prior samples of the global positioning system signals to produce accumulated matched filter results.;COPYRIGHT: (C)2009,JPO&INPIT
