PROBLEM TO BE SOLVED: To improve detachability of a mobile position measuring part of independency on application, increase usability, and realize cost reduction, by accommodating a printed board, a gyrosensor, an attitude sensor and a GPS in the same package, and making a car velocity sensor and a counter interface detachable. SOLUTION: On a printed board 1, the following are installed; an analog input 15 for a gyrosensor, an RS-232C serial communication input 14, an analog input interface 16 for an attitude sensor, an RS-232C serial communication input 13 for a DGPS, a counter input part 12 for an encoder measuring a car velocity, and an RS-232C serial communication I/O 17 for user system. Program for operating a self position is stored in an ROM 11 on the board 1. A microcomputer 10 of a CPU, a storage device, etc., is installed on the same board 1. This board 1, the gyrosensor, the attitude sensor, and the GPS are accommodated in the same package cover 2. The car velocity sensor and the counter interface are made detachable by using connectors. |
