Patent ID: 8570218

Claim:
A satellite radiowave receiver which obtains satellite signals transmitted from positioning satellites, comprising: a receiving unit which receives a radiowave in a frequency range which is set in advance, the frequency range including a frequency transmitted by the positioning satellites; a capture unit which captures the satellite signals from received signals based on the radiowave received by the receiving unit and which provides, for each captured satellite signal, a respective receiving frequency and an intensity index based on a signal intensity; a storage unit which stores the receiving frequencies of the satellite signals captured by the capture unit and intensity indexes indicating signal intensity of the satellite signals of the receiving frequencies so as to correspond with each other; and a calculation unit which calculates an average value, among the receiving frequencies, as a mean frequency by a weighted average method by the intensity indexes of the receiving frequencies according to the plurality of satellite signals stored in the storage unit, wherein the capture unit captures next satellite signals transmitted from the positioning satellites by using the mean frequency.
