Description

technical field [0001] The invention relates to a modular spacecraft orbital attitude semi-physical simulation system, which can be used for semi-physical simulation research of spacecraft orbital attitude. Background technique [0002] To carry out space activities, human beings must complete a variety of space missions. Due to the characteristics of high technology, high cost and high risk in the field of spaceflight, the selection of space mission design schemes is quite cautious. Simulation is the main way and effective method to verify the design scheme, thus establishing its important position in the development and application research of space science and technology. [0003] Simulation methods can be divided into mathematical simulation, semi-physical simulation and full physical simulation. Semi-physical simulation refers to introducing a part of the simulated object system into the simulation circuit in the form of a physical object (or physical model) for the si...
