Beschreibung
Zusammenfassung:	A positioning method includes: executing a first positioning mode or a second positioning mode, a first positioning process that is performed using a least-square method based on a positioning signal and a second positioning process that is performed using a Kalman filter based on the positioning signal utilizing a positioning result obtained by the first positioning process as a base value being performed in the first positioning mode, and the second positioning process being further performed in the second positioning mode utilizing a positioning result obtained by the second positioning process as a base value; determining accuracy of a positioning result obtained by the second positioning process performed in the executed positioning mode; and changing the positioning mode to be executed to the first positioning mode or the second positioning mode corresponding to the accuracy.
