Terminal apparatus, positioning method, Control program for terminal apparatus, and computer readable recording medium having recorded therein control program for terminal apparatus

摘要

A terminal apparatus includes a control unit and a positioning device. The control unit determines a first satellite-to-be-acquired from among a plurality of SPS, and generates an initial search frequency for the first satellite-to-be-acquired. The positioning device has a plurality of search units, and is configured to acquire the first satellite-to-be-acquired using the plurality of search units. The control unit determines first difference information, which is a difference between the initial search frequency and the frequency at which the first satellite-to-be-acquired is acquired. The control unit generates corrected search frequencies for other SPS, using the first difference information. The positioning device acquires other necessary SPS using the corresponding corrected search frequencies. The terminal apparatus can acquire SPS accurately even when there has been a frequency shift in the terminal apparatus since the last positioning. <IMAGE>
