PROBLEM TO BE SOLVED: To solve the problem wherein, when a missile continues acceleration for long hours, a frequency drift caused by the acceleration is generated in a reference transmitter for generating a reference frequency of signal processing. SOLUTION: The positioning device of a missile loaded on the missile, for positioning a self-position by receiving signals from a plurality of GPS satellites includes the reference transmitter 12 for generating the reference frequency, an accelerometer 13 for measuring an acceleration generated in the missile, and a first correction means 14 for calculating the frequency drift of the reference transmitter corresponding to the acceleration measured by the accelerometer 13. The frequency drift of the reference transmitter 12 generated by the acceleration is removed by canceling the frequency drift of the reference transmitter 12 generated actually based on the calculated frequency drift by the first correction means 14.
