Abstract

The invention provides a field calibration device for a gyro north finder. Supporting adjustment feet are fixed at the bottom of the main body seat, and a reference mounting seat is provided on the upper part of the main body seat. A collimator is installed on the reference mounting seat through a collimator adjustment device. On the box body of the block, a gyro theodolite is installed on one side of the reference mount by adjusting the support frame. The present invention uses the gyro theodolite as the collimator to establish the north reference, so it is easy to operate and has high accuracy; because the gyro theodolite and the collimator are integral structures, it has the advantage of being easy to carry, and can realize the on-site calibration of the gyro north-seeking instrument; The lead-out plane of the reference lead-out block can be calibrated for other gyro north finders after one-time determination of the north direction by the gyro theodolite, which simplifies the measurement process and improves the detection efficiency. It is suitable to be used as an on-site calibration device for a gyro north finder.

Description

technical field

[0001] The invention relates to a gyro north finder in the field of metrology, in particular to on-site calibration of a gyro north finder, in particular to an on-site calibration device for a gyro north finder. Background technique

[0002] The gyro north finder is a sensor that independently determines the true north value of the attached carrier by measuring the angular velocity of the earth's rotation. Because it is not disturbed and affected by the external magnetic field or other environments, it is widely used in radars, antennas, and military vehicles. and other fields.

[0003] The high-precision gyro theodolite’s orientation and aiming for the mobile launch of long-range weapons is the key equipment for the mobile launch of missiles from unprepared positions, and it also plays an important role in improving the response speed of artillery and effectively exerting the power of artillery.

[0004] Because the gyro north finder is an instrument for or...
