A spatial information network space-based test system and a work method thereof

Abstract

The invention provides a spatial information network space-based test system and a work method thereof. The system comprises a first ground virtual node which communicates with a network satellite system, and a second ground virtual node which communicates with the network satellite system. Communication between the first ground virtual node and the second ground virtual node is established via the network satellite system. Compared with systems and methods in the prior art, the system and method of the invention has the following advantages: 1) as for the spatial information network for future application, the network satellite system is composed of several network satellites with an integrated backbone / access function, and the network satellite acts as a network backbone node to support high-speed data transmission with a large data size, but also as a user access node to enable access to a large number of space users and ground users. By introducing the two ground virtual nodes, the space-based test system provided by the invention can verify the backbone and access mixing functions of the network satellite system.

Description

technical field [0001] The invention relates to information transmission and processing technology in the field of aerospace technology, in particular to a space information network space-based test system based on a backbone / access integrated network satellite and a working method thereof. Background technique [0002] The space information network is based on information transmission and exchange, with processing and application as the core, and aims to support all-space military and civilian missions. It is the infrastructure of large-scale information networks in the future. The space information network is an integrated network formed by synthesizing and integrating the information acquisition, information transmission, information processing, information distribution and information application functions of various space-based systems. [0003] The space information network can overcome the disadvantages of traditional satellite communication methods, greatly improve t...

Problems solved by technology

Since the current space users in orbit do not have the ability to access the space information network, the space-based test system of the space information network and its working method cannot use real on-orbit nodes as space users. Therefore, a new space information network space is urgently needed. Based on the test system and its working method, the system function of the space information network, the space environment adaptability of the network satellite system, and the backbone / access hybrid function are verified under the condition of limited space-based equipment resources
