Abstract

The invention discloses a space networking system based on a satellite group. The space networking system based on the satellite group comprises a first inter-satellite communication module and a computer module which are connected with each other, a second inter-satellite communication module and a computer module which are connected with each other, a third inter-satellite communication module and a computer module which are connected with each other, a fourth inter-satellite communication module and a computer module which are connected with each other, and a fifth inter-satellite communication module and a computer module which are connected with each other, wherein the first inter-satellite communication module and the computer module, the second inter-satellite communication module and the computer module, the third inter-satellite communication module and the computer module, the fourth inter-satellite communication module and the computer module as well as the fifth inter-satellite communication module and the computer module comprise narrowband modules, broadband modules and computer modules, the narrowband modules and the broadband modules form the inter-satellite communication modules, and the narrowband modules and the broadband modules are connected with the computer modules. According to the invention, coordinated flight management, data sharing management and formation flight management of the entire satellite group can be achieved.

Description

technical field [0001] The invention relates to a space networking system, in particular to a satellite group-based space networking system. Background technique [0002] At present, the research on satellite networking technology mainly focuses on the David constellation, and there is no relevant information on the research on the networking technology of small satellites. However, ground-based wireless networking communication technologies are very mature, including ZigBee technology, Wi-Fi technology and so on. [0003] ZigBee technology is a two-way wireless network communication technology with simple structure, low power consumption, low data rate, low cost and high reliability. The advantages of ZigBee technology are mainly reflected in: (1) reliable communication; (2) data security; (3) strong self-healing ability of the network; (4) low cost; (5) large network capacity; (6) low power consumption. [0004] Wi-Fi technology is a brand of wireless network communicati...
