Construction method of multi-coverage reconfigurable constellation, and reconfigurable constellation

Abstract

The invention discloses a construction method of multi-coverage reconfigurable constellation, and the reconfigurable constellation. The method comprises the following steps: S1, enabling a preliminaryconfiguration to comprise a plurality of quasi-polar orbital planes which are distributed along different longitude lines and have the same orbit height, and enabling the quasi-polar orbital planes to be provided with a plurality of satellites; S2, obtaining a constellation longitude coverage band multiple number n according to the global continuous service reliability requirement R, the satellite design life T, the single-satellite reliability r and the single-satellite network compensation period t; S3, obtaining a single-satellite coverage geocentric angle alpha; and S4, obtaining a plurality of numerical combinations of the satellite number S' and the quasi-polar orbital plane number P' on the quasi-polar orbital planes meeting the constellation longitude coverage band multiple numbern according to a formula, and selecting one of the plurality of numerical combinations by a user to complete construction. The multi-coverage constellation design of the polar orbital low-orbit satellite is realized, the reliability requirement and cost of a single satellite are reduced, the bottleneck problems of over-design, high cost, high network repair period requirement and the like of theinternet satellite of the low-orbit satellite are solved, and a foundation is laid for providing carrier-grade reliable operation service of the internet of the low-orbit satellite.

Description

technical field [0001] The invention relates to the field of satellite networking, in particular to a method for constructing a multi-coverage reconfigurable constellation and the reconfigurable constellation. Background technique [0002] With the development of low-orbit satellite Internet, the requirements for service reliability, continuity, and resource allocation flexibility are getting higher and higher, and the requirements for low satellite cost and mass production are also increasing day by day, which requires the improvement of low-orbit satellite constellations. Service reliability and continuity are reduced while reducing the reliability requirements for single satellites, and optimized design for constellation complementary backup. Traditional satellite Internet constellations mostly adopt a single-coverage quasi-polar orbit constellation design, which inevitably leads to extremely high reliability requirements for single satellites, which cannot meet the needs...

AI Technical Summary

Problems solved by technology

Traditional satellite Internet constellations mostly adopt a single-coverage quasi-polar orbit constellation design, which inevitably leads to extremely high reliability requirements for single satellites, which cannot meet the needs of low-cost and mass production. After a single satellite fails, it cannot meet the requirements of global continuous coverage. , and there are bottleneck problems such as over-design, high cost, and high network replenishment cycle requirements
