PROBLEM TO BE SOLVED: To extend a useable time for a receiver by reducing the consumption power and delaying consumption of a power source. SOLUTION: This receiver has a source voltage detecting part 103 for detecting source voltage, and a GPS reception control part 105 to which a source voltage value is inputted from the source voltage detecting part 103 and which controls an operation interval of a GPS reception part 101, on the basis of the inputted source voltage value. The operation interval of the GPS reception part 101 is controlled on the basis of the detected source voltage value. Consequently a reception operation is not carried out continuously at all times but is executed in accordance with the state of the source voltage. The power consumed is reduced accordingly. |
