Embodiment

[0060] In view of the severe coupling between the traditional satellite platform and the load, the present invention can realize the parallel design of the platform module and the load module, independently develop and test independently, use the multi-point support structure to realize the mechanical support between the modules, and use the hinge link mechanism between the modules to realize the mechanical support. Expand.

[0061] In the present invention, by installing the solar wing inside the satellite platform module, in order to make full use of the cross-sectional space in the fairing, the cross-sectional size of the satellite body can be increased, and the structural plate area of ​​the platform module and the load module can be further increased, which is beneficial to the satellite equipment layout, Design of various sub-systems such as deck heat dissipation.

[0062] In the invention, the platform module is arranged on the lowermost layer of the satellite, and the ...

Abstract

The invention relates to a one-rocket multi-satellite launched foldable and unfoldable modular stacked satellite configuration which comprises a satellite structure design, a thermal control design, equipment comprehensive layout, centroid optimization and the like, and one-rocket multi-satellite serial launch of modular stacked satellites is finally realized. According to the invention, adaptive adjustment can be made according to different satellite task requirements, for example, the configuration number of the load modules can be adjusted according to different load functions and weight requirements; and according to different carrier rockets, the sectional area of the satellite body is adjusted, and certain universality is achieved.

Description

technical field [0001] The invention relates to a collapsible and unfoldable modular stacked satellite configuration for multi-satellite launch, including satellite structure design, thermal control design, comprehensive equipment layout, center-of-mass optimization, etc., so as to finally realize the series connection of modular stacked satellites with one arrow and multiple satellites emission. Background technique [0002] In recent years, SpaceX, Oneweb and other aerospace companies relying on advanced industrial foundations have successively begun to build low-orbit broadband Internet networks, which quickly "ignited" the enthusiasm for the development of global commercial spaceflight. Led by low-orbit constellation systems such as Starlink and Oneweb, the low-orbit broadband communication constellation system has become the focus of the satellite industry and the communication industry. With the leap in satellite production capacity, the decline in cost, the gradual p...
