Abstract:

The compatible development trend with the coexistence of multiple systems requires additional performances of the receiver.The software receiver will take the place of the hardware receiver using ASIC and become the direction of the receiver development with its convenience and flexibility.GPS signal capturing based on software GPS receiver is investigated.The Double Dwell Sliding Correlation Method is used to capture the satellite data in the MATLAB.The simulation results prove the correctness and effectiveness of this acquisition algorithm.
