Abstract: An electronic timepiece includes a radio wave receiver, a communication unit, a memory and a processor. The radio wave receiver receives radio waves from positioning satellites. The communication unit communicates with an external device. The memory stores a program and predicted positional information on the positioning satellites. Based on the program stored in the memory, in response to a predetermined condition for an elapsed time from a valid period of the stored predicted positional information being satisfied, the processor causes the communication unit to receive predicted positional information with other information from the external device when the communication unit receives the other information.

Abstract: A mobile electronic device including: a movement detection sensor; a positioning module; a processor; and a memory, wherein the processor determines whether the device is moving on the basis of a first tentative determination result obtained by determining whether the device is moving based on a value obtained from the movement detection sensor as well as a second tentative determination result obtained by determining whether the device is moving based on positional information detected by the positioning module, and, upon determining that the device is moving, stores the positional information detected by the positioning module in the memory.

Abstract: An electronic timepiece includes a radio wave receiver, a communication unit, a memory and a processor. The radio wave receiver receives radio waves from positioning satellites. The communication unit communicates with an external device. The memory stores a program and predicted positional information on the positioning satellites. Based on the program stored in the memory, the processor shifts the timepiece between a normal operation state and a power saving state in which operation of the timepiece is restricted, depending on a status of the timepiece. In response to an elapsed time from a valid period of the predicted positional information exceeding a predetermined reference time during the power saving state, the processor causes the communication unit to receive updated data of the predicted positional information and other information from the external device when shifting the timepiece from the power saving state to the normal operation state.

Abstract: An electronic device including: a positioning module that performs positioning by receiving radio waves from navigation satellites; a movement distance detection sensor that detects movement distance; and a processor that turns on power of the positioning module and, if positioning with the positioning module has not succeeded after a first prescribed period of time has elapsed, turns off power of the positioning module, wherein if the processor detects that the movement distance detected by the movement distance detection sensor starting from when the positioning module was turned off is greater than or equal to a prescribed distance, the processor turns on power of the positioning module.

Abstract: An electronic device including: a positioning module that performs positioning by receiving radio waves from navigation satellites; a movement distance detection sensor that detects movement distance; and a processor that activates the positioning module and, if positioning with the positioning module has not succeeded after a first prescribed period of time has elapsed, suspends the positioning module, wherein if the processor detects that the movement distance detected by the movement distance detection sensor starting from when the positioning module was suspended is greater than or equal to a prescribed distance, the processor reactivates the positioning module.
