Embodiment approach

[0073] The specific implementation plan is as follows:

[0074] 1. Fix the T-mac mounting plate on the platform frame, and fix the T-mac on the mounting plate. The installation requirement is that the coordinate system of the T-mac is consistent with the platform coordinate system, so that the T-mac and the platform frame become a rigid structure, such as image 3 ;

[0075] 2. Start the laser tracker, use the electronic level and north reference to make the laser tracker establish a geographic coordinate system;

[0076] 3. Carry out transfer alignment test;

[0077] 4. After the alignment is completed, use the frame angle to output the heading angle, roll angle and pitch angle of the platform as: ψ 1 , γ 1 , θ 1 , and then use the laser tracker to track the T-mac output platform heading angle, roll angle and pitch angle as ψ 2 , γ 2 , θ 2 ;

[0078] 5. The conversion relationship between the carrier coordinate system and the geographic coordinate system can be used ...

Abstract

The invention discloses a laser tracker based transfer alignment verification method which comprises steps as follows: a verification system is put up by a control table, a submarine motion simulator and an accuracy assessment system; a testing system is correctly assembled and operated, data are collected, master inertial navigation initial alignment and transfer alignment are completed sequentially, and finally, assessment on transfer alignment accuracy is completed by using a laser tracker; a master inertial navigation system and an auxiliary inertial navigation system are mounted on a mechanical base plate of a high-accuracy three-axle table, and a basis reference is established; and a laser tracker based accuracy assessment system is used for completing accuracy assessment on transfer alignment. According to the laser tracker based transfer alignment verification method, with the adoption of the laser tracker, the data collection speed and the accuracy are improved, and the working efficiency is improved; and besides, the method has the remarkable advantages that the accuracy and the efficiency are high, real-time tracking measurement is performed, the mounting is rapid, and the operation is simple and convenient.

Description

technical field [0001] The invention belongs to the technical field of laser tracker transfer alignment, in particular to a verification method for transfer alignment based on a laser tracker. Background technique [0002] With the development of modern warfare, submarine-launched missiles have become an increasingly important medium-scale strike force. Quickly and accurately transferring and aligning its platform inertial navigation system on a submarine has become a key technology for submarine-launched missiles. The verification of the transfer alignment scheme requires the submarine to carry out the actual transfer alignment accuracy test underwater, which consumes a lot of test funds. In order to save costs and shorten the development cycle, it is necessary to build a complete laboratory transfer alignment test system and carry out related transfer alignment assessment tests before launching.
