Positioning apparatus judging movement method to control positioning timing

A positioning method of obtaining a migration path by using a first measuring section to obtain measured position data by directly measuring its own present position and a second measuring section to measure an azimuth and a movement of a user, the method comprising the steps of:

• judging a movement method of the user based on the movement of the user measured by the second measuring section;
• specifying a movement azimuth of the user based on the azimuth and the movement of the user, both measured by the second measuring section;
• calculating an average movement speed in a period in which the movement method of the user is judged to be a movement state by car at the step of judging;
• and
• obtaining a movement position by integrating a movement distance to reference position information obtained by first measuring section, the movement distance being a distance of a movement into the movement azimuth specified by the step of specifying at the average movement speed when the movement method of the user is judged to be the movement state by car at the step of judging.

A storage medium recording a program for a computer to be used for a positioning apparatus including a first measuring section to obtain measured position data by directly measuring its own present position and a second measuring section to measure an azimuth and a movement of a user, the program making the computer function as:

• a movement method judging section to judge a movement method of the user based on the movement of the user measured by the second measuring section;
• an azimuth specifying section to specify a movement azimuth of the user based on the azimuth and the movement of the user measured by the second measuring section;
• a movement speed calculating section to calculate an average movement speed in a period in which the movement method judging section judges the movement method of the user to be a movement state by car;
• and
• a position calculating section to obtain a movement position by integrating a movement distance into the movement azimuth specified by the azimuth specifying section at the average movement speed to reference position information obtained by the first measuring section when the movement method judging section judges the movement method of the user to be the movement state by car.
