Example Embodiment

[0034] In order to make the purpose, technical solution and advantages of the present invention clearer, taking the constellation design under the J2000 inertial coordinate system as an example, various implementation modes of the present invention will be described in detail with reference to the accompanying drawings.

[0035] In this embodiment, a bird's nest constellation design method is provided, such as figure 1 shown, including the following steps:

[0036] S1. Determine the total number M of constellation virtual orbital planes and the number N of satellites distributed around each virtual orbital plane j , j=1,2,...,M, take the initial value j=1.

[0037] In this embodiment, take M=6, N j Take 6, 5, 5, 6, 5, and 5 respectively, that is, deploy 32 satellites in the constellation, and at the same time ensure that they are relatively evenly distributed around the 6 virtual orbital planes.

[0038] S2. Under the J2000 coordinate system, with the oxy plane as a referen...

Abstract

The invention provides a bird nest type constellation and a design method thereof. The invention relates to a constellation design method and aims to provide a distributed design method for a plurality of satellites in the space. On the premise that the constellation performance is not influenced at all, the method solves the problem in the prior art that the conventional walker and delta constellation design method adopts similar tracks, thus being poor in viability. The method is characterized in that satellites are distributed inside several virtual orbital planes having approximate orbital parameters. Several satellites approximately in the same orbital plane are in approximate uniform distribution in the loose form. Based on the multiple collaborative coverage of the satellites, a particular task is accomplished. According to the technical scheme of the invention, the task is covered in the collaborative manner of the complex constellation configuration. In this way, the operation robustness of the constellation is improved at the same time on the premise that the constellation performance is not influenced at all.

Description

technical field [0001] The invention relates to the field of overall design of aerospace vehicles, in particular to a bird's nest constellation and a design method thereof. Background technique [0002] At present, the traditional constellation design mostly adopts design methods such as walker and delta constellation, and distributes multiple satellites on several orbital planes with basically the same orbital parameters (the ascending node is evenly distributed in right ascension), and then evenly distributes several satellites on each orbital plane. Satellites (uniform phase distribution). This method simplifies the orbit design of the constellation, and has the characteristics of easy operation and intuitive constellation configuration. However, on the other hand, the simplified constellation design makes its anti-damage ability extremely weak, and hostile targets only need a small cost (for example, fuel consumption, etc.) to achieve mass destruction of multiple target...
