General purpose simulator for microsatellite equipment

Abstract

The invention provides general purpose simulation equipment capable of being applied to different microsatellite equipment. The general purpose simulation equipment can cover various equipment assemblies in the whole testing stage of microsatellites, such as subassemblies in an attitude and orbit control subsystem, subassemblies of a monitoring subsystem and various load assemblies. Any part simulator can be reconstructed. The model of the simulator is separated from the hardware interface, and a mathematical model for equipment and the real electrical interface of equipment are simultaneously configured through upper computer software. The reconfigurability is strong, the special part simulator is not required by simulation, and only the upper computer software is configured.

Description

technical field [0001] The invention relates to a ground testing device for microsatellites, in particular to a general simulator for microsatellites Background technique [0002] In recent years, digital design technology has been widely used in aerospace field. The combination of digital design technology and hardware-in-the-loop simulation technology to quickly complete satellite design, assembly and testing has become an important direction for the development of aerospace technology. In this context, the research on virtual satellite technology has attracted more and more attention from researchers. The so-called virtual satellite is to express each subsystem and each component of the satellite with an accurate and realistic digital simulation model, and each subsystem model can be quickly and conveniently assembled into a digital analog star. It truly reflects the composition characteristics, basic performance, information flow and operation rules of the satellite. T...

Problems solved by technology

In reality, the ground test of microsatellites is the most important part before going to space. However, there are many various equipment components on the satellite, and they are often not available during the test, which affects the test efficiency. There is an urgent need for a universal simulator that can be quickly replaced without making the test burdensome. error

[0003] In the previous test system, the simulation equipment of each subsystem was not very versatile, and the simulator had to be partially or completely redesigned according to each equipment, which was not conducive to the short development period of the micro-satellite.
