Embodiment Construction

[0025] It should be noted that components in the various figures may be shown exaggerated for the purpose of illustration and are not necessarily true to scale. In the various figures, identical or functionally identical components are assigned the same reference symbols.

[0026] In the present invention, unless otherwise specified, "arranged on", "arranged on" and "arranged on" do not exclude the presence of intermediates between the two. In addition, "arranged on or above" only means the relative positional relationship between two parts, and under certain circumstances, such as after the product direction is reversed, it can also be converted to "arranged under or below", and vice versa Of course.

[0027] In the present invention, each embodiment is only intended to illustrate the solutions of the present invention, and should not be construed as limiting.

[0028] In the present invention, unless otherwise specified, the quantifiers "a" and "an" do not exclude the scen...

Abstract

The invention relates to the technical field of spatial information networks, and provides a laser link distribution method for optimizing network throughput, which comprises the following steps: carrying out visibility analysis; selecting orbital planes of the IGSO satellite and the MEO satellite to establish a link; selecting an MEO satellite to establish a link with a ground base station and calculating communication overhead; recording a link establishment routing table; and circulating the steps and recording the link establishment routing table with the least output hops. According to the method, the balance between the on-satellite data and the landing data is completed through distribution of the laser links, the problem that the landing amount of the on-satellite data is small is solved, the inter-satellite network has good throughput, and reference is provided for networking of the next generation of Beidou navigation system.

Description

technical field [0001] The present invention generally relates to the technical field of spatial information network, and in particular relates to a laser link allocation method for optimizing network throughput. Background technique [0002] At present, the Beidou-3 satellite navigation system has been successfully networked, which can meet the needs of national security and social and economic development, and provide global users with "all-weather, all-time, high-precision" positioning. At the same time, the unique short message system of the Beidou navigation system, as one of the communication methods between the satellite and the earth, has also become a Beidou feature. However, with people's continuous exploration of space, more and more on-board business data are generated by each constellation, and data landing has become one of the difficulties. mismatch. [0003] Unlike GPS that sets up base stations around the world, my country can only set up ground base stati...
