A method for calculating a position of a moving vehicle using a first unit that performs a correlation process on a satellite signal received from a satellite to capture the satellite signal and calculate the position and velocity of the moving vehicle and a second unit capable of detecting at least the velocity of the moving vehicle includes: calculating a determination velocity which is the velocity determined using the results of the calculation by the first unit and the results of the detection by the second unit; determining a correlation integration period used when the first unit performs the correlation process using the error in the determination velocity; and calculating the position of the moving vehicle using the results of the calculation by the first unit and the results of the detection by the second unit.
