Title:
ELECTRONIC APPARATUS, CONTROLLER, AND CONTROL PROGRAM
Document Type and Number:
Japanese Patent JP2019152540
Kind Code:
A
Abstract:
To provide an electronic apparatus, a controller, and a control program with which it is possible to accurately calculate a travel distance when acquiring position information on a prescribed cycle by a satellite positioning system.SOLUTION: A control unit (10A) of a travel meter (1A) performs the processes of: acquiring satellite positioning system position information on at least a prescribed cycle that is the position information acquired by a satellite positioning system; detecting a forward azimuth multiple times during a prescribed cycle; determining, by a determination unit (11), whether or not an azimuth difference between the previously detected forward azimuth and a forward azimuth at the current position is greater than or equal to a threshold angle; acquiring, by a current position information acquisition unit (12), the position information of the current position when the azimuth difference is greater than or equal to the threshold angle; and calculating, by an arithmetic unit (13), a travel distance from an initial position to the current position on the basis of the position information of the current position and the satellite positioning system position information of the initial position.SELECTED DRAWING: Figure 1
