  • Patent number: 10983222
    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.

  • Patent number: 10935665
    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.

  • Patent number: 10890666
    Abstract: A satellite radiowave receiving device includes a receiver performing a receiving operation of radiowaves transmitted from a positioning satellite and a processor controlling a positioning operation. The processor performs the positioning operation within at least a predetermined maximum positioning interval from a last positioning operation using preliminarily obtained date and time information and valid positional information on the positioning satellite to obtain a current position of the satellite radiowave receiving device and date and time information. The processor causes the receiver to perform the receiving operation within at least a predetermined date and time updating interval shorter than the predetermined maximum positioning interval from a last time when date and time information is obtained from radiowaves transmitted from a positioning satellite to obtain date and time information without the positioning operation.

  • Patent number: 10866326
    Abstract: A moving state determining device includes a receiver receiving radiowaves from a positioning satellite and a processor. The processor determines a moving state of a satellite radiowave receiving unit based on a motion state measured by a sensor which measures a motion state, and performs a positioning operation based on information received by the receiver to obtain a current position and an error range thereof. In determining the moving state, a positioning operation result obtained when the error range satisfies a predetermined accuracy standard can be used. The error range is calculated based on a positioning accuracy and a deviation of the obtained current position and a predicted position calculated in accordance with the moving state. The positioning accuracy is obtained by combining each position of positioning satellites from which radiowaves are received and each receiving state of the radiowaves.
