Abstract:
1. A receiver comprising: a reception circuit section that receives a signal from a positioning satellite; a memory that stores a received signal that has been received by the reception circuit section; a set-unit signal strength calculation section that calculates a signal set having a maximum signal strength from a plurality of signal sets, each of the plurality of signal sets including two or more received signals for a specific period of time that differ in storage position in the memory; a specific-time signal strength calculation section that calculates a received signal for the specific period of time having the maximum signal strength from the received signals for the specific period of time included in the signal set having the maximum signal strength and the received signals stored at storage positions preceding or subsequent to that of the signal set having the maximum signal strength; and a determination section that determines a read start position of the received signal for the specific period of time calculated by the specific-time signal strength calculation section to be a read start position used for a correlation process for acquiring the signal from the positioning satellite.
