Description

technical field [0001] The invention relates to a fast simulation test technology of a satellite control system, which uses two super real-time nested fast simulation test methods: hardware super real-time and software super real-time. Background technique [0002] Commonly used test methods for satellite control system testing include: real-time simulation and semi-physical simulation. This type of simulation test method needs to run the on-board software on a real on-board computer. Limited by hardware conditions, this type of simulation test method can only be tested according to the real-time step size, and the simulation of long-period tasks is time-consuming and labor-intensive. [0003] The ultra-real-time simulation test uses virtual computer technology, and the on-board software runs in the on-board computer environment simulated by the test equipment, which can make the simulation time (the internal running time of the tested system) longer than the simulation time...
