Satellite platform configuration with extensible truss node cabin

Abstract

The invention provides a satellite platform configuration with an extensible truss node cabin, which comprises a configuration body and a solar cell array. The solar cell array is arranged on the south and north side surfaces of the configuration body. The configuration body comprises a service cabin and a node cabin, and the node cabin is installed on the upper portion of the service cabin. According to the node cabin, the four extensible truss systems are fixed through the cuboid frame structure, the node cabin can be connected with other sub-platforms in four horizontal directions at the same time, a plurality of satellite sub-platforms are connected into a whole, and an ultra-large platform is constructed for complex tasks. The fixing frame is connected with a force bearing cylinder ofthe service cabin through a node cabin bottom plate in the longitudinal direction, and a cross-shaped and central circular combined reinforcing frame is pre-buried in the node cabin bottom plate, sothat the whole satellite platform has high rigidity.

Description

technical field [0001] The invention relates to the technical field of satellite platforms, in particular to a configuration of a satellite platform with an extendable truss node compartment. Background technique [0002] The position of the geostationary orbit is an extremely valuable limited space resource. At present, the international competition for it is becoming increasingly fierce, and the difficulty of applying for a new orbit position is gradually increasing. In order to make full use of the precious geostationary orbit resources and ease the fierce competition for orbit positions, super-large on-orbit assembling integrated satellite platforms are the development trend of high-orbit satellites. Ultra-large satellites can realize comprehensive detection functions and improve the utilization efficiency of geostationary orbit positions. However, for very large satellites, due to the limitation of carrying capacity, it is necessary to carry out modular decomposition o...

Problems solved by technology

However, the disadvantages of the independent node module solution are: (1) it needs to be carried into orbit by the space shuttle, and the connection and installation between the node module and other cabin sections is performed by the mechanical arm on the space shuttle; (2) due to the limited transportation capacity of the space shuttle, the The size of the outer envelope of the node compartment is restricted, which in turn limits the configuration size of the entire star after assembly
