Paper Abstract

The weak signal environment puts forward the great challenge to GPS signal acquisition algorithm. In this paper, the signal model of GPS receiver is established, in which the Doppler compensation is considered. The segment correlation video integration method using envelope detector is adopted, and this method is optimally designed by deriving the optimum IF integration time and optimum segment number. In order to avoid the effect of navigation data bit-transition, the suboptimum IF integration time is also proposed, which performs close to the optimum approach.
