Problems solved by technology

However, the previous satellite ground simulation test system used PC-based boards, which had low flexibility and a long simulation cycle, and could not truly and effectively reflect the satellite's in-orbit situation. For the Windows+TRX architecture development test program, the programming technology level is high. The development cycle is long, which is not suitable for the rapid development of satellite test systems

Embodiment Construction

[0023] The inventive idea of ​​the present invention is: the satellite ground closed-loop simulator based on the PXI architecture of the present invention selects the NI Veristand software development environment, and can configure the functions and interface characteristics of the modules while the project is running. This flexibility and versatility It is convenient to realize the advanced development concept of "simultaneous design and test", which greatly shortens the test cycle; at the same time, the operating system selected by the PXI architecture controller is the LabVIEW RT system, which greatly shortens the simulation cycle and increases the traditional simulation cycle to 1ms. The ground simulation test of the satellite is closer to the real on-orbit situation of the satellite, and has the advantages of fast speed, high precision, strong reliability, and easy operation, which makes the test of the attitude control subsystem and the central computer more perfect.

Abstract

The invention provides a satellite ground closed-loop simulator based on a PXI architecture. The satellite ground closed-loop simulator is used for ground closed-loop testing of a satellite attitude control system. The PXI architecture is adopted for the designed satellite ground closed-loop simulator to implement flexible configuration of each module, implemented main functions comprise implementation and output of simulation data of a dynamics simulation computer, an attitude control sensor simulator and an attitude control execution mechanism simulator. The computation period of the dynamics simulation computer is 1 ms, and the satellite ground closed-loop simulator has the advantages of being quick in speed and high in safety and flexibility.

Description

technical field [0001] The invention relates to the technical field of satellite ground testing, in particular to a satellite ground closed-loop simulator based on a PXI framework. Background technique [0002] The satellite attitude control system is used to realize the satellite attitude and pointing control, which is an important prerequisite to ensure the normal operation of the satellite subsystems to complete the flight mission. Due to the importance of the attitude control system, the test of the attitude control subsystem has become the primary task of the satellite ground test. The satellite ground closed-loop simulator can well complete the ground closed-loop simulation test task of the satellite attitude control system. In order to quickly and reliably complete the ground test work, designing an open, general-purpose, and automated ground test system has become an important direction for satellite test work. . [0003] In the development process of satellite att...
