Summary:PROBLEM TO BE SOLVED: To provide a satellite signal tracking device and method that can cope with the dynamic characteristic change of satellite signals. SOLUTION: The satellite signal tracking device includes tracking modules 130, 140, 150 tracking satellite signals received from a satellite to produce satellite base measurement results. The tracking modules 130, 140, 150 include a plurality of sub-tracking modules 130-1, 130-2, 130-3 using different integrated times from the satellite signals to produce satellite base measurement results respectively. Signals can be rapidly acquired again by tracking the satellite signals following the dynamic characteristic change of the satellite signals, and position solutions of high reliability can be obtained.
