Abstract: A satellite radiowave receiving device includes a receiver and a processor. The receiver acquires and receives radiowaves from a positioning satellite. The processor performing a positioning operation based on the radiowaves received by the receiver to obtain a current position of the satellite radiowave receiving device. The processor causes the receiver to stop an acquiring operation of radiowaves from a new positioning satellite under a predetermined condition while radiowaves are being acquired from a required number of positioning satellite for the positioning operation. If an error range of the obtained current position no longer satisfies a predetermined accuracy standard during a stop of the acquiring operation, the processor causes the receiver to resume the acquiring operation.

Abstract: A satellite radiowave receiving device includes a receiver and a processor. The receiver receives radiowaves from a positioning satellite. The processor performs a positioning operation based on the radiowaves received by the receiver to obtain a current position. The processor calculates an error range at the current position based on a positioning accuracy and a deviation. The positioning accuracy is obtained by combining each position of a plurality of positioning satellites and receiving state of radiowaves from each of the plurality of positioning satellites, and the deviation is a deviation of the current position and a predicted position calculated in accordance with a travelling state of the satellite radiowave receiving device.

Abstract: A satellite radio signal receiver includes a receiving section which receives radio signals from satellites and demodulates the signals to identify bits of the demodulated signals as received bits; and a processor. The processor compares each received bit of the satellites with estimated bits which are estimated to be received within a possible deviation range from a current date and time acquired as a reception timing of the received bit to obtain comparison result information between the received bits and the estimated bits in relation to deviations within the possible deviation range with respect to each of the satellites, integrates the comparison result information on the received bits of the satellites, specifies a deviation that satisfies a match condition of the received bits and the estimated bits based on the integrated comparison result information, and acquires date and time information based on the deviation that satisfies the match condition.
