Satellite radiowave receiving device, electronic timepiece, method for controlling positioning operations, and storage device

A method of controlling the positioning of a satellite radiowave receiving device including a receiver receiving radiowaves from a positioning satellite, the method comprising:

• obtaining a current position by performing a positioning operation based on the radiowaves received by the receiver, and
• calculating an error range at the current position based on a positioning accuracy and a deviation, the positioning accuracy being obtained by combining each position of a plurality of positioning satellites and receiving state of radiowaves from each of the plurality of positioning satellites, the deviation being a deviation of the current position and a predicted position calculated in accordance with a travelling state of the satellite radiowave receiving device.

A non-transitory computer readable storage device storing a program readable by a computer in a satellite radiowave receiving device including a receiver receiving radiowaves from a positioning satellite, the program causing the computer to:

• obtain a current position by performing a positioning operation based on the radiowaves received by the receiver, and
• calculate an error range at the current position based on a positioning accuracy and a deviation, the positioning accuracy being obtained by combining each position of a plurality of positioning satellites and receiving state of radiowaves from each of the plurality of positioning satellites, the deviation being a deviation of the current position and a predicted position calculated in accordance with a travelling state of the satellite radiowave receiving device.
