Problems solved by technology

The invention patent "Mars capture brake control high-fidelity simulation method and device" mentions that the capture brake of Mars is carried out by simulation, and no actual physical verification is carried out.
Although the patent "Semi-Physical Simulation Method and System for Optical Autonomous Navigation in the Mars Capture Section" realizes semi-physical simulation, it does not consider the influence of the gravity of Mars on the actual trajectory of the Mars rover.

Description

technical field [0001] The invention relates to a full physical simulation experiment device and method for planetary detection, capture, braking and device separation, and belongs to the field of aircraft ground simulation. Background technique [0002] With the rapid development of satellite technology, in order to ensure the effective operation of the spacecraft in orbit, the spacecraft needs a full physical simulation test on the ground. Therefore, the construction of the ground simulation test system is an important guarantee for the development of space technology. Mathematical simulation can only simulate the impact of the deep space environment on the planetary capture brake and the separation of the orbiter and the lander, but cannot effectively simulate the impact of factors such as installation errors, single-machine measurement, and high-thrust control. Physical simulation tests are used to analyze the feasibility of track control strategies and algorithms to im...
