Abstract

The acquisition of weak GPS signals is a challenging problem. The current methods for acquisition of weak GPS signals mainly depend on aiding, in which the GPS receiver needs priori information from base-station to promote weak GPS signal acquisition and tracking. It is unavailable in some remote locations since the area may not be covered by the base-station. On the other hand, in the state-of-art unaided GPS receivers, the weak GPS signals acquisition requires long Pre-detection Integration Time (PIT), such that the computation is complex and time-consuming. This paper proposes a computational efficient method to speed up acquisition operations. Finally, we evaluate the efficiency of the method through simulations.
