Satellite attitude orbit control software digital closed-loop test system and method

Abstract

The invention provides a satellite attitude orbit control software digital closed-loop test system and a method. The system comprises an interface simulation end which is connected with an iSystem system, a remote measurement remote control end and a dynamics model end through a network interface and is used for carrying out interface simulation for carrying out data transmission, the iSystem system used for operating the attitude orbit control software, monitoring an operation state and collecting the data of an external interface, the remote measurement remote control end used for receiving an inputted remote control instruction, sending the remote control instruction to the attitude orbit control software and receiving and processing the remote measurement result data, and the dynamics model end used for receiving the control information outputted by the attitude orbit control software, accomplishing calculation of a satellite peripheral attitude orbit model and sending the data of an input part to the attitude orbit control software. According to the system, the interface simulation end forms the digital simulation operation environment and a flexible customization external interface and interacts with the peripheral dynamics model, and thereby white box test content effects can be realized through a black box test method.

Description

technical field [0001] The invention relates to the field of simulation testing of satellite attitude and orbit control software, in particular to a digital closed-loop test system and method for satellite attitude and orbit control software with freely configurable interfaces. Background technique [0002] Attitude and orbit control software is satellite attitude and orbit control software, which is responsible for receiving stand-alone data, outputting control actions after attitude calculation, and completing satellite actual tasks. It is the center of all stand-alone satellites and corresponding software. It is an embedded software. Safety and robustness directly affect the success or failure of satellites. [0003] Since the attitude control software is embedded software and has a large number of external interfaces to communicate with many lower stand-alone computers, the difficulty in building the black box test platform for the attitude control software lies in the s...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a satellite attitude and orbit control software digital closed-loop test system with freely configurable interface, to solve the problem that the existing satellite attitude and orbit control software test system is limited by the input means of the black box test platform, and many test cases can only Problems with testing with a white-box approach

[0006] The second purpose of the present invention is to provide a digital closed-loop test system for satellite attitude and orbit control software with freely configurable interfaces, so as to solve the problem that existing satellite attitude and orbit control software test systems are difficult to operate, and the validity of test input is difficult for testers. The dependence is too large, which is not conducive to finding the functional defects of the test software
