摘要

Acquisition module is an important part in GPS receiver. Three current acquisition methods are introduced, and on the basis of parallel frequency search, a new algorithm that changing step length and quadratic curve fitting in frequency domain is given to improve the precision of acquisition. At the same time, parallel frequency search and parallel code phase search are combined to implement code phase acquisition and the high precision of acquisition on Doppler frequency offset. The simulation result shows that the acquisition error can be controlled in a smaller scope at different SNRs through the method given in this paper.
