Abstract

The invention discloses an on-satellite transparent exchange method for a high-flux satellite communication system. The method aims at the requirement of 'one belt and road' for large-capacity and large-bandwidth satellite communication coverage. However, the high-throughput satellite communication system has the disadvantage that a plurality of gateway stations need to be built abroad and returning to the domestic only by depending on international optical cables. A satellite user wave beam and a feed wave beam are hinged; partial frequency bands of user beams are gathered to a territorial feed beam, and the territorial feed beam is communicated with a domestic ground gateway station, so that high-throughput satellite communication does not completely depend on the limitation of foreign deployment gateway stations and rental international optical cables. The use flexibility of a high-throughput satellite communication system is improved, and the use scene of the system is expanded. Compared with the traditional high-throughput satellite communication system architecture, the method provided by the invention overcomes the problems that the rate from the user beam to the feed beam is high and the user beam cannot be downloaded through one feed beam, and solves the problem that the beams cannot be directly connected on the satellite.

Description

technical field

[0001] The invention belongs to the field of satellite communication, and in particular relates to an on-board transparent switching method of a high-throughput satellite communication system. Background technique

[0002] my country's national high-throughput satellite program will launch 7 geostationary orbit satellites one after another starting in 2017. In 2023, relying on the east and west to enhance two satellites, it will form a satellite communication capability covering the entire territory of China and the Asia-Pacific region with a capacity of 400Gbps. It will meet my country's "Belt and Road" national strategy and the high-speed satellite communication guarantee needs of member countries. In 2025, global coverage will be further realized, and the total communication capacity will reach about 2Tbps. my country's first on-orbit high-throughput satellite Zhongxing-16 was launched in 2017. It uses a transparent forwarding system. Its resource allocatio...

Embodiment

[0026] 1. System composition

[0027] The high-throughput satellite communication system consists of 1 GEO high-throughput satellite, 3 high-throughput satellite gateway stations distributed in different regions (at least one of which is deployed in China), and 1 high-throughput ground data center deployed in China constitute;

[0028] GEO high-throughput satellites have M user beams and 3 feeder beams,

[0029] The three gateway stations are connected to the data center through ground optical fibers to form a high-throughput satellite communication system. Based on the high-throughput satellite communication system, the network architecture is abstracted, such as figure 1 shown.

[0030] 1.1 Satellite Payload Composition

[0031] The difference in satellite payload structure is the biggest difference between the present invention and traditional high-throughput satellite fixed beam resource allocation satellite load. Specifically, the satellite payload part of the presen...
