| Abstract: | Fast and reliable system simulation is very important to the design of dual frequency GPS receiver as well as various receive algorithms. The GPS system simulation platform was constructed based on MatLab/Simulink. The whole GPS system and the implementation method were analyzed, and then the integrated simulation block was given, and the L2 carrier phase tracking on this platform was realized. The result shows the availability and reliability of this platform. |
