Embodiment Construction

[0100] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0101] The embodiment of the present invention discloses a satellite communication system, such as figure 1 As shown, including: low-orbit satellite LEO network, medium-orbit satellite MEO network and high-orbit satellite GEO network, where:

[0102] GEO network for data transmission with MEO network;

[0103] MEO network, used for data transmission between GEO network and LEO network;

[0104] The LEO network is used for data transmission between the MEO ne...

Abstract

The embodiment of the present invention provides a kind of satellite communication system and method, and above-mentioned system comprises: low-orbit satellite LEO network, middle-orbit satellite MEO network and high-orbit satellite GEO network, wherein: GEO network is used for carrying out data communication with MEO network Transmission; MEO network, used for data transmission between GEO network and LEO network respectively; LEO network, used for data transmission between MEO network and ground communication network respectively. By adopting the satellite communication system provided by the embodiment of the present invention, a relatively large area of ​​communication coverage can be achieved through a small number of satellites included in the GEO network, MEO network, and LEO network, and the multi-layer satellite network includes fewer satellites. The number of satellites reduces the number of satellite network nodes and reduces the frequency of routing switching, which also reduces the transmission delay of the satellite communication system to a certain extent.

Description

technical field [0001] The invention relates to the technical field of satellite communication, in particular to a satellite communication system and method. Background technique [0002] With the rapid development of space information network, satellite communication system has become an indispensable part of information infrastructure due to its advantages of large coverage area, fast transmission speed and strong mobility. [0003] At present, most of the existing satellite communication systems are single-layer satellite communication systems composed of multiple satellites at the same orbital height. For example, the single-layer satellite communication system includes: a high-orbit single-layer satellite communication system, a medium-orbit single-layer satellite communication system, and a low-orbit single-layer satellite communication system. Among them, the high-orbit single-layer satellite communication system has ViaSat1 (broadband satellite communication system ...
