Positioning apparatus judging moving method to control positioning timing

A positioning method of obtaining a migration path by using a position measuring section to obtain measured position data by measuring a position, a movement measuring section to measure an operation, and information of a rail route map, the method comprising the steps of:

• controlling operation timing of the position measuring section to make the position measuring section discontinuously obtain the measured position data;
• judging a moving method based on a measurement result of the movement measuring section;
• and
• judging the migration path in a period of an electric train movement judged at the step of judging a moving method based on position information measured by the position measuring section and the information of the rail route map.

A storage medium recording a program for a computer to be used for a positioning apparatus, the computer including a position measuring section to obtain measured position data by measuring a position, a movement measuring section to measure an operation, and a map data storage section to store information of a rail route map, the program making the computer function as:

• a positioning controlling section to control operation timing of the position measuring section to make the position measuring section discontinuously obtain the measured position data;
• a moving method judging section to judge a moving method based on a measurement result of the movement measuring section;
• and
• a migration path judging section to judge a migration path in a period of an electric train movement judged by the moving method judging section based on position information measured by the position measuring section and the information of the rail route map.
