Positioning method, program, positioning device, and electronic apparatus
First Claim
1. A positioning method in a positioning device, comprising:
- receiving positioning signals transmitted from a plurality of positioning satellites;
measuring a first current position by performing first positioning processing using a least square method and the received positioning signal;
determining whether or not a result of the first positioning processing satisfies a positioning change condition set beforehand as a condition for change of positioning processing;
stopping the first positioning processing when it is determined that the result of the first positioning processing satisfies the positing change condition; and
measuring a second the current position by performing second positioning processing using a Kalman filter, the received positioning signals and the result of the first positioning processing after the stopping the first positioning processing.

Abstract
A positioning method in a positioning device includes: measuring a current position by receiving positioning signals transmitted from a plurality of positioning satellites and performing first positioning processing using a least square method; determining whether or not a result of the first positioning processing satisfies a positioning change condition set beforehand as a condition for change of positioning processing; and measuring the current position by receiving the positioning signals transmitted from the plurality of positioning satellites and performing second positioning processing using a Kalman filter after stopping the first positioning processing when it is determined that the result of the first positioning processing satisfies the positioning change condition.
