Abstract
A method of determining reliability of a received signal is provided, which includes correlating a received signal from a satellite to a replica code, determining reliability of the received signal according to a predetermined reference using a first value and a second value, the first value being a correlation value of a peak phase obtained from the correlating and the second value being a correlation value of a phase delayed for a predetermined phase from the peak phase and changing the reference according to the satellite.
