Abstract: A satellite radio wave receiving device includes: a receiver that receives a satellite radio wave to identify a reception signal; and a processor that acquires primary date and time information from the identified reception signal and outputs a date and time notifying signal indicating date and time based on the primary date and time information to an outside of the satellite radio wave receiving device. The date and time notifying signal includes at least a timing notifying signal indicating a predetermined timing. The processor determines the predetermined timing without consideration of a timing of a second synchronization point which is a leading edge of every second in the date and time based on the primary date and time information, and outputs the timing notifying signal at the predetermined timing.

Abstract: A radio wave receiver includes a radio wave reception processor and a processor. The radio wave reception processor receives radio waves and obtains signals transmitted from positioning satellites. The processor sets reception start timing of the radio wave and controls the radio wave reception processor to start reception. The radio wave reception processor performs acquiring operation to acquire transmission signals from a number of positioning satellites necessary for computing a present position. After the acquiring operation, the radio wave reception processor obtains signals necessary for computing the present position from the acquired transmission signals in an obtaining time from an obtaining start timing to an obtaining end timing determined depending on a format according to the positioning satellite. The processor sets the reception start timing so that certain reception conditions are satisfied.
