No-cable on-orbit service receivable satellite

Abstract

The invention provides a no-cable on-orbit service receivable satellite. The no-cable on-orbit service receivable satellite comprises a satellite body, a changeable module, a passive docking mechanism and a wireless communication system, wherein the satellite body is used as a main supporting structure, the changeable module is placed outside the satellite body to be convenient for module changing, the passive docking mechanism is used for receiving on-orbit gas and liquid filling, and the wireless communication system is used for realizing management and data exchanging of each part of a platform; and real-time access and removal of each module within the satellite are supported by using a wireless bus. Therefore, according to the no-cable on-orbit service receivable satellite, the changing of an on-orbit module can be convenient to operate, the service life of the satellite is actually prolonged, the adaptation of the satellite to multiple tasks is actually enhanced, restriction of communication network wiring to the structure, configuration and layout of a satellite system is eliminated, the configuration and layout of a satellite module can be designed according to application needs, the module is very convenient to detach and mount, a plug-and-play capacity is realized, the on-orbit module changing task is very easily realized and easily-consumed materials are supplemented so that the service life of the satellite is further prolonged.

Description

technical field [0001] The invention belongs to the field of aerospace technology, and relates to a cableless acceptable on-orbit service satellite, which can realize management and data exchange of various components of the platform through a wireless information system, can accept on-orbit module replacement, and can also accept on-orbit add-ons. Note. Background technique [0002] Spacecraft on-orbit service refers to a type of space operation that involves extending the life of various spacecraft and improving the ability to perform tasks through the cooperation of humans, robots or both in space. On-orbit module replacement and on-orbit filling are the most typical efficiency-enhancing on-orbit service methods. Through module replacement and on-orbit refueling, the application efficiency of the spacecraft can be restored, maintained or improved, and the replacement and replenishment of faulty modules, consumables, etc. can be realized, so as to ensure the normal operat...

Problems solved by technology

[0005] In the existing technology, the constraints of the traditional satellite data network on the satellite system structure and configuration layout make the satellite design lack of pertinence, flexibility and scalability, and the weight of the interface hardware and cables connecting each subsystem in the satellite accounts for 10% to 15% of the overall weight of the satellite, which severely restricts the configuration layout and increases the difficulty of on-orbit replacement
