Embodiment approach

[0072] During the static evaluation in the laboratory, after the transfer and alignment of the sub-inertial navigation platform, use the autocollimation theodolite to evaluate the accuracy of the alignment;

[0073] The specific implementation process of the assessment is as follows:

[0074] 1. According to image 3 As shown, install and fix two autocollimating theodolites;

[0075] 2. Align and level the autocollimating theodolite a and b;

[0076] 3. Use the autocollimation theodolite b to obtain the reading F of the alignment between the platform azimuth prism and the autocollimation theodolite b 1 The reading F aligned with the reticle of the autocollimating theodolite a and the autocollimating theodolite b 2 ;

[0077] 4. Use the autocollimation theodolite a to obtain the reading F of the crosshairs of the autocollimation theodolite b and the autocollimation theodolite a 3 and the reading F of the northing datum and the autocollimating theodolite a 4 ;

[0078] 5....

Abstract

The invention discloses an auto-collimation theodolite 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 for collecting data, master inertial navigation initial alignment and transfer alignment are completed sequentially, and finally, assessment on transfer alignment accuracy is completed by using an auto-collimation theodolite; 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 an auto-collimation theodolite based accuracy assessment system is used for completing accuracy assessment on transfer alignment. According to the auto-collimation theodolite based transfer alignment verification method, the auto-collimation theodolite based testing system is put up, and the auto-collimation theodolite based accuracy assessment system is used for completing accuracy assessment on transfer alignment, so that the accuracy assessment on transfer alignment is realized in a laboratory environment, and the initial alignment accuracy can be rapidly and accurately estimated.

Description

technical field [0001] The invention belongs to the technical field of laboratory verification of transfer alignment, in particular to a verification method for transfer alignment based on an autocollimation theodolite. 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.
