Abstract

A positioning device measures a position of a vehicle by including a controller. The controller provides (i) a first positioning system to obtain a first positioning result having a first accuracy by performing positioning using a signal from a GNSS satellite and (ii) a second positioning system to obtain a second positioning result having a second accuracy higher than the first accuracy, by using acquired vehicle-related information, instead of or in addition to the first positioning result. The controller selects, as a selected positioning system to obtain a selected positioning result, either (i) the first positioning system or (ii) the second positioning system. In response to determining that the second accuracy of the second positioning result is lower than the first accuracy of the first positioning result, the controller is configured to switch the selected positioning system to select the first positioning system.
