Simulation service star used for on-orbit service technical identification

Abstract

A simulation service star used for on-orbit service technical identification comprises a communication subsystem, an attitude and orbit control subsystem, an operation mechanism subsystem, a pushing subsystem and a power source subsystem. The communication subsystem achieves communication between the attitude and orbit control subsystem and a ground control station through a wireless communication module by means of a wireless router and is used for simulating an on-orbit universe wireless communication link. The operation mechanism subsystem is used for completing on-orbit operation mission simulation under the control of a central processing unit. The pushing subsystem is used for controlling horizontal movement and rotation movement of the simulation service star under the control of the central processing unit, so that the simulation service star is in butt joint with a targeted aircraft according to expected motion. The power source subsystem provides a working power source for electric equipment of the simulation service star. The attitude and orbit control subsystem comprises a relative attitude and orbit measurement unit and the central processing unit. By the adoption of the simulation service star, the dynamic characteristics of a service aircraft are simulated more veritably in the on-orbit environment.

Description

technical field [0001] The invention relates to the field of space robots, in particular to a simulated service star used for on-orbit service technology verification. Background technique [0002] Space on-orbit service technology is a research hotspot in space technology in the world today, and it is also one of the top 100 national strategic projects during the "13th Five-Year Plan". Fully carry out space on-orbit service ground simulation experiments. The design of simulated service satellite is an important link to realize the technical simulation of ground on-orbit service. [0003] At present, the ground simulation used for on-orbit service technology can be divided into microgravity simulation system based on free fall motion, microgravity simulation system based on parabolic flight, water floating experiment system, hanging wire counterweight experiment system and plane according to different microgravity simulation methods. There are several types of air flotatio...

AI Technical Summary

Problems solved by technology

[0004] Some of the planar air-floating simulation service satellites reported publicly at present do not have integrated manipulators, and cannot simulate the on-orbit operation of space manipulators; some only eliminate the gravity of the manipulators, and the satellite body is still fixed, so it cannot simulate satellites and manipulators. Coupling movement between robotic arms; some simulated service stars integrate mechanical arms but require external power supply cables, which will seriously interfere with the movement of simulated service stars and affect the experimental results
