Embodiment Construction

[0012] As shown in the figure, a support adjustment foot 1 is fixed on the bottom of the main body seat 2, and a reference mounting seat 3 is provided on the upper part of the main body seat. The light pipe is installed on a box body with a plane mirror 6 and a northward reference lead-out block 7, and a gyro theodolite 8 is installed on one side of the reference mounting seat through an adjustment support frame 9.

[0013] Installation and use:

[0014] The main body support and adjustment feet are used for the stable support and level adjustment of the main body, and the stable support is realized through the threaded rotating ball head and the ball head cup support structure; the main body is an integrated structure, and the adjustment support frame is installed on one side for installation and adjustment of the gyro theodolite , the other side is installed with a reference mount; a collimator and a collimator adjustment device are fixedly installed on the reference mount, ...

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...
