Simulated target satellite for technical verification of in-orbit service

Abstract

The invention provides a simulation target satellite for on-orbit service technology verification. The simulation target satellite comprises a communication subsystem, an orbit and attitude control subsystem, a fault simulation subsystem, a propulsion subsystem, and a power subsystem. The communication subsystem realizes the communication between the orbit and attitude control subsystem and a ground control station by using a wireless communication module and is used for simulating an on-orbit space and earth wireless communication circuit and is used for the information exchange between the simulation target satellite and ground monitoring equipment. The orbit and attitude control subsystem comprises an absolute position and attitude measurement unit, a relative position and attitude measurement target and a central processing unit. The fault simulation subsystem comprises a simulated solar wing, a fault simulation detection unit, and a simulation solar wing drive device. The propulsion subsystem controls the horizontal movement and rotation movement of the simulation target satellite. The power subsystem provides a working power supply for each electrical equipment of the simulation target satellite. According to the simulation target satellite, the dynamic characteristics of a service spacecraft in an orbit environment are simulated realistically.

Description

technical field [0001] The invention relates to the field of space robots, in particular to a simulated target 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. [0003] The simulated target star is the object provided for the simulated service star to implement on-orbit operation, how to design an integrated and multi-functional simulated target star is very important. [0004] In the current public reports, some only have a docking structure, which can only simulate the rendezvous and docking process, but cannot simulate the fault removal task; some will be fixed by the base of the service object, and cannot simulate the dynamic coupling phenomenon during the on-orbit operation; ...

Problems solved by technology

[0004] In the current public reports, some only have a docking structure, which can only simulate the rendezvous and docking process, but cannot simulate the fault removal task; some will be fixed by the base of the service object, and cannot simulate the dynamic coupling phenomenon during the on-orbit operation; some The simulated target star needs an external power supply cable, which will seriously interfere with the movement of the simulated service star and affect the experimental results
