Method for constructing testing environment of satellite control system

Abstract

The invention discloses a method for constructing a testing environment of a satellite control system. The method comprises the following steps of classifying component parts of a satellite control system to be tested, establishing a standardized model of each part and performing modular packaging; classifying input and output ports in each standardized model according to respective signal type, and counting various signals of a single part model; performing number maximized configuration on hardware interfaces of test equipment according to types and numbers of parts possibly used by different satellite control systems; and fixedly connecting hardware interface signals of the test equipment and modular models, and fixedly connecting part models and a dynamical model to form a closed loop. By the method, the current situation of constructing the testing environment of the satellite control system by 'customizing for each satellite' is changed, the development speed is improved, the efficiency of constructing the testing environment is improved by modularizing and standardizing the interfaces, the method is convenient to use, and manpower, material resources and time cost are saved.

Description

technical field [0001] The invention belongs to aerospace testing technology and relates to rapid establishment, recovery and transplantation of a testing environment during ground testing. Background technique [0002] The satellite control system is an important service subsystem of the satellite. It is responsible for the attitude and orbit control of the satellite. How to verify the correctness of the control scheme more effectively on the ground is the key to the problem. [0003] The ground test verification work includes mathematical simulation and physical simulation. The difference between physical simulation and mathematical simulation is that in physical simulation, the real components of the satellite need to be connected, and some simulators are used to simulate various states of the satellite in orbit. This kind of simulation test is called "mock flight test". Because it is a real component, the physical characteristics of the component are closer to the real ...

AI Technical Summary

Problems solved by technology

Therefore, the test environments of different systems are different, they cannot be used universally, it is difficult to build and transplant, and the requirements for people are high.

[0006] With the increase of satellite development tasks, the establishment and use mode of the original test environment can no longer meet the rapidly growing demand for satellite testing
