A remote test system for attitude and track control subsystem

Abstract

A long-distance test system for the attitude and track control subsystem includes: a remote signal conditioning computer, two optical fiber transmission equipment, a near-end test computer, audio equipment and video equipment; the remote signal conditioning computer completes the conditioning and processing of long-term test signals Combing, optical fiber transmission equipment to realize long-distance transmission or reception of long-distance test signals, audio equipment, through optical fiber transmission equipment and the other end of the audio equipment to achieve point-to-point communication function, used for remote signal conditioning computer or near-end test computer debugging and remote The monitoring of the audio signal at the end; the video equipment sends the acquired video signal to the video equipment at the other end through the optical fiber transmission equipment for the monitoring of the remote signal conditioning computer. The invention satisfies the requirements of long-distance signal transmission on signal type, transmission distance and transmission reliability, and satisfies the use safety problem of remote equipment under unattended conditions, and improves the long-distance test capability of the attitude and track control subsystem ground test system .

Description

technical field [0001] The invention relates to a long-distance test system for a remote sensing satellite attitude and orbit control subsystem, which can be used for long-distance testing of the attitude and orbit control subsystem. Background technique [0002] The attitude and orbit control subsystem is one of the important subsystems of the satellite, and its main function is to maintain the stability of the three-axis attitude of the satellite to the ground or to other targets. The main function of the ground test system of the attitude and orbit control subsystem is to complete the testing and verification of various functions and technical indicators of the attitude and orbit control subsystem. At present, according to the different test status of the whole satellite, the test technology status of satellite attitude and orbit control subsystem can be divided into short-term test status and long-term test status. In the short-line test state, the ground equipment of t...
