To provide a receiver determining the propriety of tracking, using separately obtained navigation data.

A receiver may be applied to a GPS receiver or the like. In the receiver, a receiving means receives a satellite signal from a satellite, a frequency conversion means converts the satellite signal to an intermediate frequency, an integration means outputs an integration signal by integrating a reference signal and the converted signal, a reference signal generation means generates the reference signal of a prescribed frequency, and a tracking determination correlation value output means outputs a tracking determination correlation value that is a correlation value between integration signal and the reference signal. A prediction data obtaining means obtains prediction data of the navigation data. The tracking determination means performs comparison processing of comparing the tracking determination correlation value with the prediction data, and performs the tracking determination on the basis of the result of the comparison processing.
