| Abstract: | In this paper the GPS performance for signal acquisition time and detection probability is analyzed on the basis of the principle of GPS signal acquisition. The relationship of acquisition performance versus carrier to noise ratio and integration time is given. The acquisition performance of a GPS receiver which adopts high accuracy clock and multi correlator technology is also analysed. The simulation result shows that the advanced acquisition technology is important. |
