Abstract

The invention discloses a multi-parameter and high-precision star map detection device for a star simulator. The multi-parameter and high-precision star map detection device is composed of a height adjusting mechanism, an azimuth angle adjusting mechanism, a pitch angle adjusting mechanism, a theodolite host engine base, a theodolite axis system, a theodolite optical system, a theodolite eyepiece system, a transfer lens and an area array CCD (Charge Coupled Device). Under the condition that a theodolite structure is not damaged, compressive high-precision detection of an angular distance between stars, a single-star position, a single-star field angle, single stars and the like of the star simulator can be realized.

Description

technical field [0001] The invention relates to a high-precision detection technology for a star simulator, in particular to a multi-parameter high-precision star map detection device for a star simulator. Background technique [0002] With the development of my country's aerospace technology, higher requirements are put forward for the accuracy of optical navigation sensors. As the key ground calibration equipment of the optical navigation sensor, the star simulator directly determines the accuracy of the optical navigation sensor. [0003] Star simulators are divided into static star simulators and dynamic star simulators according to the different ways of displaying star maps. Whether it is a static star simulator or a dynamic star simulator, the main technical indicators include inter-star angular distance, single star position, single star opening angle and single star, etc. These technical indicators determine the accuracy and applicable occasions of the star simulat...

Problems solved by technology

In view of the fact that the existing star map detection device cannot realize the comprehensive detection of inter-satellite angular distance, single-star position, single-star opening angle and single-star etc. The human eye interpretation will introduce reading errors, or the detection accuracy will be reduced due to the difference of the collimating optical lens used in conjunction with the CCD, and the use of the radiometer can only detect single stars in a completely black background. Adjustment mechanism, azimuth angle adjustment mechanism, pitch angle adjustment mechanism, theodolite host base, theodolite shaft system, theodolite optical system, theodolite eyepiece system, adapter lens and area array CCD, the building can realize the angular distance between stars of the star simulator, single Comprehensive high-precision detection of star position, single star angle and single star, etc., the detection accuracy of inter-star angular distance is better than 0.4pixel, the detection accuracy of single star position is better than 0.2pixel, and the detection accuracy of single star angle is better than 0.2pixel. The detection accuracy of star magnitude is better than 0.1 magnitude star
