Applying a fine Doppler acquisition method on software GPS receiver with field experiment

This paper presents a method on fine Doppler frequency acquisition in software GPS receiver, which is implemented in Matlab/Simulink. Compared with the existing FFT-based approach, it speeds up the handover from acquisition to tracking stages, and it requires much less computational burden. A field experiment is made to show the positioning performance of the software GPS receiver, which verifies the correctness of the applied acquisition and tracking techniques.
