METHOD OF ACQUIRING ERROR CORRECTION VALUE OF REFERENCE FREQUENCY, TERMINAL DEVICE, AND RECORDING MEDIUM

摘要

A method for acquiring an error correction value of a reference frequency, a terminal device, and a recording medium are provided to restrict the widening of a search range by using a first drift which is calculated using a reference frequency. A method of acquiring an error correction value of a reference frequency comprises the following steps of: calculating a first drift of a local oscillator by using the reference frequency; calculating a search range of a satellite signal by using the first drift; calculating a second drift of the local oscillator by using a receiving frequency of the satellite signal; calculating a reference frequency error by calculating a difference between the first drift and the second drift; calculating the error correction value of the reference frequency by taking statistics of a plurality of the reference frequency error.
