PROBLEM TO BE SOLVED: To attain a positioning signal search device that can search for a positioning signal at high speed.SOLUTION: A positioning signal search device 10 comprises: a control part 20; a plurality of signal search parts 41 and 42; and a timing signal generation part 30. When a cold start state is detected, the control part 20 sets a positioning satellite of a different combination to the plurality of signal search parts 41 and 42 as a search object satellite, and sets a common search frequency range to the plurality of signal search parts 41 and 42. When a hot start state is detected, the control part 20 selects a positioning satellite that has a high probability of capturing and tracking, and sets the selected positioning satellite to the plurality of search signal parts 41 and 42 as a common search object satellite. The control part 20 divides the search frequency range with respect to all of the selected positioning satellite, and sets the divided search frequency range to the plurality of search signal parts 41 and 42. |
