Abstract:

The research of the key techniques of baseband control is of great importance based on China Area Positioning System (CAPS) as the research platform. The system framework of the simulator is developed. A signal simulator of the CAPS was studied. The general block diagram was given, and the function of each module was divided and planned. The generation of satellite position parameters, the simulation of the ionosphere delay. The control of carrier DCO and code DCO are the key techniques that must be solved for the development of the CAPS simulator. In accordance with the characteristics of CAPS, the formulas of the relevant parameters were given. Based on these techniques, the CAPS simulator was developed. Test results show that the design is feasible, and the CAPS simulator can be applied to test the performance of the receiver on signal acquisition, signal tracking and positioning.

Key words: communication, simulator, ionosphere, doppler, carrier digitally controlled oscillator(DCO), code DCO
