| Abstract: | The paper introduces an adaptive Kalman filter for GPS time difference comparison data processing. Using Matlab language, we simulate the Kalman filter program, analyze and process the time difference comparison between GPS signal and cesium atomic frequency standard. Finally the paper also introduces the algorithm for FPGA digital chip implementation. |
