AUTOMATIC SURVEYING DEVICE

摘要

PROBLEM TO BE SOLVED: To obtain an automatic surveying device in which speed and position correction can be operated without using any speed detector, miniaturization and a light weight enough for an operator to easily carry this can be realized, and a point direction can be easily recognized. SOLUTION: This device is constituted of an inertia information correction arithmetic unit 16 for storing speed, and position information from a compact and light INS15 in a strap-down system for obtaining the directional change of the detection axis of an accelerometer 17 for an inertial coordinate system by a triaxial integrated gyro 18, correcting the speed and position, and correcting the position information again based on an initial coordinate.
