Abstract

A joint rapid simulation test method of ground dynamics software and on-board software, which initializes the ground dynamics software according to the preset ground dynamics software initialization parameters; The ground dynamics software and on-board software in the physical real-time simulation replace the hardware interface part of the semi-physical real-time simulation with software to form a joint rapid simulation test method to judge the output state of the on-board sensor and the state of the on-board actuator. , The correctness of the attitude, position and speed of the satellite solves the problems in the semi-physical simulation that the problem is difficult to locate, the debugging process is too complicated, and the interpretation of the test results is not comprehensive enough, and the comprehensiveness of the interpretation of the test results, the debugging efficiency and the software development efficiency are improved.

Description

technical field [0001] The invention relates to a combined rapid simulation test method of ground dynamics software and on-board software, which is particularly suitable for rapid simulation test during on-orbit flight and landing of a lunar lander, and belongs to the technical field of rapid simulation test during flight and landing. Background technique [0002] At present, the general spacecraft control system test needs to go through mathematical simulation, on-board software software platform simulation and semi-physical real-time simulation. The mathematical simulation is mainly used to verify the scheme design and algorithm. The algorithm implementation does not need to consider the on-board hardware operating environment. Therefore, the use of A set of ground dynamics software and the algorithm implementation software written according to the plan; the on-board software software platform simulation is mainly to verify the on-board software rather than the on-board har...
