Example Embodiment

[0078] The present invention will be further illustrated with reference to the accompanying drawings.

[0079] It should be noted that each component in the drawings may be exaggerated for illustrative description, and it is not necessarily a ratio. In each of the drawings, the same components as the same or functionally are equipped with the same reference numerals.

[0080] In the present invention, unless otherwise indicated, "arranged" "," arranged above "and" arranged above "and" arranged above "did not exclude the case where the intermediates were present between the two. Further, "arranged or above" only indicates the relative positional relationship between the two components, and in a certain case, if it is inverted the product direction, it can also be converted to "arranged under or below", but also NS.

[0081] In the present invention, each embodiment is intended to illustrate the aspects of the invention without being construed as limiting.

[0082] In the present in...

Abstract

The invention provides a feed link switching method based on global service distribution, which comprises the following steps of: during feed link distribution, sorting all ground stations according to the service volume of an area where the ground stations are located according to the existing service distribution on the ground, and sequentially distributing landing satellites to a plurality of antennas of the ground stations according to priorities; when a landing satellite is distributed to a ground station, according to three parameters of satellite visual time, a feed link rate and an on-satellite load capacity, downloading on-satellite data needing to land on the satellite to the maximum extent while the capacity of a network between the satellite and the ground is optimized, so that the utilization rate of the feed link is improved.

Description

technical field [0001] The invention relates to the technical field of LEO satellites, in particular to a feeding link switching method based on global service distribution. Background technique [0002] The low-orbit satellite network can cover the whole world. As an excellent supplement to the ground communication network, it provides Internet access services for all regions of the world and is a key part of the next-generation air-space-ground integrated communication system. However, the feed link between the satellite and the ground gateway will be switched frequently due to the high-speed movement of the satellite relative to the ground and the change of the satellite coverage. In the traditional low-orbit satellite network, due to the limitations of technology and application scope, the number of satellites and ground stations is limited. When selecting a ground station, the satellite usually chooses the nearest ground station as the landing gateway. With the proposa...
