POSITIONING METHOD, PROGRAM, POSITIONING DEVICE, AND ELECTRONIC APPARATUS
First Claim
1. A positioning method in a positioning device, comprising:
- 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.

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.
