Abstract

Abstract:

A realization scheme of hardware receiver system using for the fast acquiring of high dynamic GPS signal is proposed. According to the acquiring speed requirements of the GPS receiver and the hardware platform,this scheme chooses 2 sets of average samples among 5 sets after the averaging sampling technique processing. It realizes the real-time acquiring of the single satellite GPS signals in cost of small accuracy decline. The simulation results and the hardware implementation results of the high dynamic GPS signal show the validity and the feasibility of the method.

Key words: real-time acquiring, high dynamic, GPS receiver, FPGA
