Large commercial remote sensing satellite platform configuration and assembly method

Abstract

The invention provides a large commercial remote sensing satellite platform configuration and an assembly method. The platform configuration comprises a satellite platform main structure, a docking ring and a solar cell array, wherein the satellite platform main structure comprises a butt joint plate, storage box plates, partition plates, a camera plate, outer plates and truss rod assemblies. Thestorage box plates and the partition plates are arranged on the butt joint plate. A plurality of storage box plates and a plurality of partition plates are arranged and are transversely and longitudinally arranged to form a well-shaped structure; the camera plate is arranged above the well-shaped structure; the four outer plates are supported by the truss rod assemblies and arranged around the well-shaped structure; every two adjacent outer plates are connected through the corresponding outer skin; the solar cell array is arranged on the outer surfaces of the outer plates; the docking ring isfixed below the butt joint plate; subsystem single-machine devices are installed on the storage box plates and the partition plates; a propelling subsystem assembly is installed on the butt joint plate; and the two storage tanks are symmetrically installed relative to the mass center of the platform. The configuration is small in structural weight proportion, small in inertia, good in mechanical property, good in solar cell array area expansibility and convenient to assemble and operate.

Description

technical field [0001] The invention belongs to the technical field of large commercial remote sensing satellites, and in particular relates to a large commercial remote sensing satellite platform configuration and assembly method. Background technique [0002] The overall satellite can be simply divided into two parts: payload and satellite platform. The payload of a satellite is a dedicated device on the satellite. For example, the payload of a remote sensing satellite is an optical camera; the satellite platform is also often called a service module, and its main function is to serve the payload, provide power distribution, attitude control, orbit control, and business measurement and control. etc., to ensure that the satellite can work normally in orbit. At present, most commercial remote sensing satellite configurations adopt the traditional deck structure. In order to meet the requirements of strength and dynamic characteristics, the main structure of the satellite of...

AI Technical Summary

Problems solved by technology

At present, most commercial remote sensing satellite configurations adopt the traditional deck structure. In order to meet the requirements of strength and dynamic characteristics, the main structure of the satellite often makes the structural weight account for a large proportion of the entire satellite, and the rotational inertia of the entire satellite is large, which is not conducive to satellite in-orbit. Fast maneuvering; Most of the remote sensing satellite configurations install the payload in the load cabin, resulting in a small installation space for single equipment in the cabin and poor assembly operability; large remote sensing satellites consume a lot of power and have a high demand for solar array area. Traditional satellite platforms The structure is single, and the installation space of the solar cell array is limited, which is not conducive to the expansion of the area of ​​the solar cell array and the installation of different types of solar cell arrays
