The invention discloses a pointing three-super satellite platform system based on a space manipulator, relates to the technical field of aerospace application, and solves the problems that an existing undisturbed load platform cannot realize quick and large-range maneuvering of effective loads and a traditional three-super stable platform is low in vibration isolation bandwidth, high in cost and the like. Therefore, the stable transmission of data and the maximization of solar energy utilization are ensured. Rapid maneuvering of the effective load module is achieved through the space manipulator, the connecting module and the effective load module are connected through the Stewart-structured non-contact actuator interface, master-slave collaborative attitude movement is achieved through the connecting module and the effective load module, and ultrahigh pointing precision of the effective load is achieved. The interface module is provided with a non-contact energy transmission system and a wireless information transmission system, a high-precision non-contact actuator and a high-precision non-contact sensor are adopted, it is guaranteed that the effective load module is not affected by vibration of the supporting module, and ultrahigh stability in the working process is achieved.
Description
technical field [0001] The invention relates to the technical field of aerospace applications, in particular to a three-supersatellite platform system based on space manipulators. Background technique [0002] With the continuous deepening of human space exploration, higher requirements are put forward for the pointing accuracy and pointing stability of spacecraft in space missions. Space interferometry mission (SIM), terrestrial planetary explorer (TPF), The payloads of space-based lasers (SBL) require ultra-high pointing accuracy and a good micro-vibration isolation environment. Ensuring the pointing accuracy and stability of the spacecraft is actually to ensure the pointing accuracy and stability of the payload. The modules that implement support functions mainly include flywheels, thrusters, refrigerators, and solar panels. These components will also generate a large amount of vibration while completing their corresponding tasks, which will greatly reduce the pointing ac...
