Abstract

A ground dynamic software and on-satellite software combined rapid simulation test method comprises the steps of initializing ground dynamic software according to an initial parameter, preset, of theground dynamic software; and substituting a hardware interface part in semi-physical real-time simulation by software to form the combined rapid simulation test method according to a design idea thathardware and software are decoupled to develop and debug and by combining the ground dynamic software and on-satellite software in semi-physical real-time simulation, and judging an output state of anon-satellite sensor, a state of an on-satellite execution mechanism and correctness of gesture, position and speed of a satellite. By the combined rapid simulation test method, the defects that the problem in semi-physical simulation is difficult to position, the debugging process is too complicated and test result interpretation is not comprehensive are overcome, and the comprehensiveness of thetest result interpretation, 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 soft platform simulation and semi-physical real-time simulation. Among them, the mathematical simulation is mainly to verify the scheme design and algorithm. When the algorithm is implemented, it does not need to consider the on-board hardware operating environment. A set of ground dynamics software and algorithm implementation software written according to the scheme; the on-board software soft platform simulation is mainly to verify the on-board software rather than the on-board hardware, using rea...
