Abstract

In a mobile system, a power supply switch 34 receives the output from a clock 33 and a CPU 1, and selectively supplies the power supplied from the Bup line to position measuring means comprising a GPS receiver 4, a GPS antenna 5, a gyro 6, and a transit distance sensor 7 via a stabilizer 35, enabling the position measuring means to continue the position measuring operation after stopping the main operation of the mobile system.

Claims

1. A mobile system which is mounted on a mobile unit, comprising:

a position measuring section for measuring the position of said mobile unit; and

a controller for controlling said position measuring section to continue the position measuring operation after stopping a main operation of said mobile system.

2. The mobile system according to claim 1, further comprising a positioning stopper for stopping said position measuring operation under the control of said controller.

3. The mobile system according to claim 2, wherein said positioning stopper comprises a clock section which starts the clocking after stopping the main operation of said mobile system.

4. The mobile system according to claim 1, further comprising an operation stop detector for detecting the stop of the main operation of said mobile system;

wherein said operation stop detector is provided on a power line for supplying an electric power to said mobile system.
