Embodiment Construction

[0025] The air-floating motion simulator can be used on the ground to simulate the space activities of spacecraft under the condition of microgravity. This is a unique ground-based full-physics simulation method in the process of developing satellites and other spacecraft. The access loop is very important to verify the correctness of the design of the spacecraft control system and to verify the function and performance of the actual control system.

[0026] Such as figure 1 As shown, the three-degree-of-freedom air-floating simulator of the present invention includes a translation platform and an attitude platform; the main function of the attitude platform is to control the precise pointing of the pointing rod and to control the pose of the simulator in real time; the main function of the translation platform is to pass the plane The air bearing places the whole simulator in a microgravity environment in the form of air bearing; the translation platform and the attitude pla...

Description

technical field [0001] The invention relates to a high-precision pointing and positioning three-degree-of-freedom air flotation simulator, in particular to a high-precision terminal pointing and positioning device in a space microgravity environment. Background technique [0002] In the process of intelligent autonomous space penetration, it is feasible to use the air flotation simulator to provide space penetration effectiveness verification. Based on the guidance of various detectors such as infrared detectors and active radar installed on the air flotation simulator, the guidance control system calculates the target position in real time and realizes target tracking according to the program angle guidance, and completes the intelligent penetration verification test. [0003] Traditional mathematics and hardware-in-the-loop simulation cannot truly simulate the working errors and response delays of each system, and it is difficult to accurately describe and quantitatively e...
