[0053] Embodiment 1: Space Distributed Constellation Design Method

[0054] The space distributed constellation refers to multiple heterogeneous mission satellites arranged in the same space orbit position. Inter-satellite link interconnection is used to realize inter-satellite synchronization and large-capacity data transmission. Through joint cooperation of distributed loads, wide-area coverage is jointly realized. , large-capacity information exchange, flexible network communication, space information service and other functions, and can independently realize topology and function reconstruction in orbit, and a collection of satellite groups that can quickly self-heal when a failure occurs;

[0055] Space distributed constellations can provide a self-organizing, reconfigurable, and robust space networked information base platform, and mission satellites equipped with various space-based information acquisition and application loads can be plug-and-play on demand. Access to ...

[0094] Example 2: Space Distributed Constellation Design with 3 Heterogeneous Mission Satellites

[0095] Assume that there are three heterogeneous mission satellites Sat1, Sat2 and Sat3, among which Sat1 is mainly equipped with communication function load, and Sat2 and Sat3 are equipped with business processing load, and the above three satellites need to form a space distributed constellation. According to the space distributed constellation design method disclosed in the present invention, the specific design method is as follows:

[0096] Formulate the constellation co-orbit scheme: the constellation contains 3 satellites in total, which can be applied to the flat longitude isolation, inclination angle isolation and eccentricity isolation strategy. Here, the common orbit method is relatively simple and the topological state is relatively stable. The flat longitude isolation strategy is used as the constellation Common rail scheme.

Abstract

The invention belongs to the field of satellite communication, and discloses a spatial distribution type satellite group design method. The method comprises the following steps: formulating a satellite group common rail scheme; designing a topological structure; formulating a functional load and a division strategy; formulating an in-orbit configuration reconstruction and function reconstruction method; designing a satellite group flexible networking method; designing an inter-satellite high-speed data transmission method; designing a multi-satellite distributed synthetic coverage method; designing a multi-satellite distributed joint calculation method; designing a satellite group intelligent self-healing method; designing a rapid emergency adjustment method; and designing a star group scale expansion and star group cluster construction method. The method has the advantages that the orbital utilization efficiency is improved through multi-satellite common-orbit combination, the satellite group capacity is enhanced through high-speed interconnection transmission, quick response is achieved through on-orbit self-healing reconstruction, the coverage area is increased through a distributed array antenna, the on-satellite processing capacity is improved through distributed joint calculation, and the method is particularly suitable for design of space distributed satellite groups.

Description

technical field [0001] The invention belongs to the field of satellite mobile communication, in particular to a satellite communication constellation design method. Background technique [0002] Building a space-ground integrated space information network is an inevitable development trend of my country's space information system. Space-based information network, as the basic transmission platform of space information network, needs to support the ultra-long-distance, long-delay, uninterrupted and reliable transmission of deep space exploration. It supports high-dynamic, broadband real-time transmission of earth observation downwards, and at the same time guarantees the communication of important value users such as ocean navigation, aviation access, and emergency rescue. Therefore, it is necessary to ensure high-performance and high-reliability spatial information support capabilities. The current space-based information network is facing problems such as lack of orbital pos...
