Abstract

This paper modifies the traditional half bit acquisition algorithm and proposes a new algorithm for weak signal acquisition. The new algorithm can increase coherent integration time to 15ms and the sensitivity of acquisition is improved in the new algorithm. The performance of acquisition algorithm aided by INS (Inertial Navigation System) is analyzed. Using the INS information to improve the running speed of the weak signal acquisition algorithm, the GPS software receiver can capture the weak signal quickly. The simulation results indicate that the new algorithm can capture the indoor feeble signals with SNR (signal-to-noise ratio) of-39dB rapidly.
