Problems solved by technology

[0004] However, the traditional spacecraft structure design method is task-oriented and driven by user needs. The tasks and functions are relatively single, and the development cycle is relatively long. It is not suitable for the goal of "faster, better and more economical" for micro-nano satellites.

Embodiment 1

[0032] see Figure 2A and Figure 2B , this embodiment provides a satellite platform that does not contain a propulsion system and can perform missions in low earth orbit. The micro-nano-satellite structure includes four side panels 11 , four half-side panels 12 , an upper top panel 13 , a lower bottom panel 14 and twenty-four inter-panel connectors 15 . A circular hole 123 is opened on the half-side panel 12, which can provide an earth observation field of view for the optical load 141, and can be used in earth observation tasks. Meanwhile, a low-gain antenna 124 is installed on the half side panel 12 . In addition, stand-alone devices with field of view requirements, such as the star sensor 122 , are placed on the half side panel 12 . Other sub-systems, such as power control module 113, communication module 114, data command module 115, momentum wheel 116, etc., are respectively placed on the inner surface of side panel 11.

Embodiment 2

[0034] see Figure 3A and Figure 3B, the present embodiment provides a satellite platform containing a propulsion system that can be executed in a geosynchronous transfer orbit mission. In order to meet the energy demand, the satellite platform is equipped with two unfolded solar panels 118 and is equipped with a thruster 142, so that it has orbit maneuvering ability. The deployment mechanism 117 of the solar sail is installed on the side panel 11 . The load 131 is installed on the upper roof 13 , and other subsystems are installed on the side panels 11 . The satellite structure is composed of six side panels 11 , four half-side panels 12 , an upper top panel 13 , a lower bottom panel 14 and twenty-four inter-panel connectors 15 in total.

Abstract

The invention relates to a modular reconfigurable micro-nano satellite structure. The modular reconfigurable micro-nano satellite structure is composed of a group of assorted and replaceable base components; the modular reconfigurable micro-nano satellite structure mainly comprises a lateral panel, a semi-lateral panel, an upper top plate, a lower bottom plate and plate connecting pieces. The lateral panel and the semi-lateral panel are integrated into a standard port for a single machine and load, and the standard port has fully repeatable characteristic; the design for the upper top plate and lower bottom plate depends on a specific task, a user only needs to integrate the standard port of mounting equipment on two kinds of base components, and the modular batch production can be realized for the same lateral panel and semi-lateral panel structures. Different combinations of five components can make up different satellite structures. The satellite structure can be quickly designed, assembled, integrated and tested according to requirements of different tasks. The modular reconfigurable characteristic shortens the satellite development period, reduces the repeated development cost and improves the micro-nano satellite flexibility.

Description

technical field [0001] The invention relates to the field of aerospace satellites, in particular to a modular and reconfigurable micro-nano satellite structure. Background technique [0002] Since the beginning of the 21st century, with the rapid development of computers, new materials, micro-nano, micro-electronic machinery, high-density energy and new space propulsion technologies, micro-nano satellites have become the most active in the aerospace field with a new concept and new design ideas. research direction. With the development goal of "faster, better, and more economical", micro-nano satellites adopt a large number of high-tech technologies, which have the advantages of high functional density and technical performance, low investment and operating costs, strong flexibility, short development cycle, and low risk. Micro-nano-satellites are light in weight and are usually used as auxiliary loads for large-scale launch missions. They are free from high-cost large-scal...
