Stationary orbit ultra-large type assemblable satellite platform configuration and on-orbit assembly method

Abstract

The invention provides a stationary orbit ultra-large type assemblable satellite platform configuration, which belongs to the technical field of spacecrafts, and comprises a mother platform, a transition sub-platform I and a transition sub-platform II, a functional sub-platform I and a functional sub-platform II, a functional sub-platform III and a functional sub-platform IV, an energy module I and an energy module II, and a mechanical arm I and a mechanical arm II, wherein the mother platform is a control center of a whole satellite; the transition sub-platform I and the transition sub-platform II are respectively connected with the mother platform through connecting devices; the functional sub-platform I and the functional sub-platform II are respectively connected with the transition sub-platform I through connecting devices; the functional sub-platform III and the functional sub-platform IV are respectively connected with the transition sub-platform II through connecting devices; the energy module I and the energy module II are respectively connected with the transition sub-platform I and the transition sub-platform II through connecting devices to supply power; the mechanicalarm I and the mechanical arm II are installed on the transition sub-platform I and the transition sub-platform II correspondingly to execute an on-orbit assembling task. The platform configuration issuitable for expansion, can adapt to on-orbit construction of large satellites with the on-orbit flight weight of 10-20 t, is applied to various types of satellites and service stations, and is wide in application range.

Description

technical field [0001] The invention relates to the technical field of spacecraft, in particular to a geostationary orbit ultra-large assembleable satellite platform configuration and an on-orbit assembly method. Background technique [0002] With the development of satellite application level, the importance of satellite to national defense technology and national economy and people's livelihood is increasing day by day. In recent years, major aerospace countries have continued to increase their investment in the aerospace industry, and the number of satellite launches has been increasing year by year, with an average annual increase of more than 20% in the number of global satellite launches. Geostationary orbit satellites cause the particularity of the orbit, and play an extremely important role in the fields of global communication, relay, and earth observation. However, geostationary orbit resources are very scarce, and my country's high-orbit satellites will face incr...
