Abstract

In this paper, in the deep research GPS signal capture principles foundation, carried on the simulation using Matlab to the GPS signals capture process to realize and to analyze. Software-based GPS(SGR) Receiver can analyst processing the GPS signal at the lowest level of GPS raw signal data from the antenna. The simulation result further confirmed this methods accuracy and the feasibility, this to further studies under the true environment in the simulation platform the GPS signal, the improvement satellite receiving unit performance has the very vital practical significance.
