| Abstract: | The principle and key technique of Multi-channel Satellite Signal Simulator are introduced; software and hardware implementation schemes are also designed. The software part is implemented by using VC ＋ ＋ 6. 0 soft platforms and the hardware signal processing circuit board is realized by FPGA. The communication of software and hardware is realized via serial ports. The simulator has been applied in R＆D process of the satellite navigation system successfully, and it possesses the fundamental function of a simulator. Besides, the simulator can simulate the Doppler Effect Shift in the frequency of Satellite Signal. The simulator can provide a vivid high dynamic signal environment for the validations of orientation performance, signal track and capture performance of a receiver. |
