Embodiment Construction

[0042] Such as figure 1As shown, a typical satellite attitude control system includes an attitude control processor, a measurement component, an execution component, and a satellite body. The attitude control processor is the core computing unit of the satellite attitude control system. The measurement components include various attitude sensors and their interface devices carried by the satellite under test, such as gyroscopes, sun sensors, magnetometers, star sensors, etc. The execution components include various control mechanisms carried by the satellite under test and their interface devices, such as magnetic torque devices, momentum wheels, jet mechanisms, etc. The satellite body includes the satellite shell and all other on-board devices. When the satellite attitude control system is working, the attitude control processor reads the data collected by the measurement components, and sends control commands by applying the attitude measurement and control algorithms on t...

Description

technical field [0001] The invention relates to the field of satellite attitude control system testing, in particular to a ground simulation device for small satellite attitude control system testing. Background technique [0002] The attitude control system is one of the most complex subsystems in satellite design. During the development process on the ground, due to the lack of a real space environment, the attitude control system cannot be tested directly, but can only be simulated. Satellite attitude control system simulation is divided into three types: mathematical simulation, semi-physical simulation, and full-physical simulation. For the development of small satellites, the full physical simulation based on the air bearing platform is generally seldom used due to the high cost. Mathematics simulation and semi-physical simulation are the main simulation means of small satellite attitude control system. [0003] Mathematical simulation is a simulation method that co...
