Abstract: |
For the problem of satellite signal simulation with high temporal and spatial resolution,a real-time forecast method of satellite position is designed.The method is based on field programmable gate array(FPGA) device.According to the satellite orbit parameters,the satellite position is calculated and given at the sampling time of each analog signal,so as to support the simulator to give high-precision analog signals to the greatest extent.The effectiveness of the method is verified by simulation. |
