An apparatus and a method for tracking satellite signal are provided to increase high reliable GPS receiver by tracking satellite signal according to the changing of characteristic of the satellite signal. In an apparatus and a method for tracking satellite signal, tracking modules(130,140,150) produce a satellite-based measurement result by tracking the satellite signal received from the satellite. A plurality of assistant tracking modules(130-1,130-2,130-3) produces a respective satellite-based measurement result by using the different accumulation time from the satellite signal while including an accumulator and a track loop. The accumulator generates a correlation signal by using the accumulation time from the satellite signal. |
