Description

technical field

[0001] The invention belongs to the technical field of ground verification of spacecraft navigation, guidance and control systems, and in particular relates to a cross-scale verification platform for space task ground motion reproduction. Background technique

[0002] The degree of development of aerospace engineering determines whether it can seize the high-tech commanding heights and maximize the use of space resources. my country is actively carrying out aerospace technology research. In order to successfully complete space missions in extremely harsh space environments, sufficient experimental verification must be carried out on the ground. Reproducing the movement of the spacecraft in space on the ground can fully verify all aspects of the spacecraft in the space mission and ensure the smooth completion of the space mission. The most obvious feature of spacecraft movement in the space environment is the orbital movement in the microgravity environment, wh...
