The space mission ground movement reconstruction cross-scale verification platform comprises a free base system, a hang spring active compensation system, a magnetic suspension system, an experiment spacecraft system, a coordination master control system, a communication system and a monitoring center. Hang spring coarse compensation and magnetic suspension fine compensation are combined with each other to form a gravity compensation system, high-precision micro-gravity environments can be provided for the experiment spacecraft system, the free base system and the gravity compensation system are combined with each other, accordingly, the experiment spacecraft system and the micro-gravity environments can synchronously move, and micro-gravity environments without time and space constraints can be provided for the experiment spacecraft system. Compared with existing gravity compensation method, the space mission ground movement reconstruction cross-scale verification platform has the advantages that the micro-gravity environments are high in reliability and adaptability, easy to implement and maintain and free of time and space constraints, and accordingly the space mission ground movement reconstruction cross-scale verification platform can be applied to ground tests and verification on the reasonableness and the feasibility of space mission implementation schemes with different mission requirements, different orbit characteristics and different work modes.

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] Before the actual implementation of space missions, all-round comprehensive verification must be carried out on the ground before the test can be carried out. As a key part of the implementation of space missions, the ground verification stage can verify the rationality and technical feasibility of space mission plans, and provide a basis for space missions. The on-orbit verification of the execution plan provides a scientific basis. The success of the ground verification phase of space missions depends to a large extent on whether the verification methods used can truly reflect the characteristics of the mission completion process. In a nutshell, these features include: the execution process o...

Problems solved by technology

Existing ground experiment systems for verifying space missions have (1) time constraints, making it difficult to obtain long-term continuous weightlessness effects; (2) space constraints, ignoring absolute orbital motion, and only being able to perform experimental verification of some subtasks or subsystems. As a result, the overall test verification of space missions is very difficult; (3) Some existing gravity compensation methods have extremely high requirements on the waterproof and gas-proof performance of electromechanical equipment, and due to the influence of fluid viscosity and resistance, it is also difficult to meet the maneuverability test of complex missions Therefore, it is urgent to develop a space mission verification platform with high reliability, strong adaptability, easy implementation and maintenance, and unlimited time and space, so as to complete high-fidelity space mission ground testing and verification.
