Embodiment Construction
[0038] The drawings constituting a part of the present invention are used to provide a further understanding of the present invention, and the schematic embodiments of the present invention and their descriptions are used to explain the present invention, and do not constitute an improper limitation of the present invention.
[0039] Such as figure 1 As shown, the present invention provides a control method for the expansion and reconstruction of satellite constellation network on the same orbital plane: the present invention assumes that the satellite to be expanded has been launched or has maneuvered to the desired orbital plane through a different orbital plane. Assuming that there are initially K satellites in a certain orbital plane, in order to improve the coverage performance of the satellite constellation networking system, Q satellites need to be expanded in the same orbital plane, then there will be S=K+Q satellites in the orbital plane.
[0040] First, determine the...

The present invention provides a control method for satellite constellation network expansion and reconstruction on the same orbital plane. The method firstly determines satellite constellation orbit optimization decision variables; determines satellite constellation optimization decision variable constraint conditions; determines satellite constellation expansion and reconstruction objective function; determines The fuel consumption evaluation function of satellite constellation expansion and reconstruction control; using the NSGA-II algorithm based on multi-objective optimization, determine the target phase of the single satellite of the satellite constellation, so as to obtain the target phase of each satellite in the satellite constellation after expansion and reconstruction; determine the control The pulse and pulse time, and use the control pulse at the pulse time to adjust the satellite to the corresponding target phase. The invention further improves the revisit coverage performance of the satellite constellation system to the target area.
Description
technical field [0001] The invention belongs to the field of satellite orbit control, and in particular relates to a control method for expansion and reconstruction of satellite constellation network on the same orbit plane. Background technique [0002] In order to realize global navigation, regional radar early warning and regional observation, satellite constellation networking has become an important means. Restricted by factors such as the number of satellites, launch capability, and economy, it takes a long time for the satellite constellation networking system to be finally deployed. Therefore, the overall performance of the satellite constellation networking system is usually gradually improved by means of staged deployment. Constellation configuration optimization is a very complicated problem. In the design, it is often necessary to consider a huge optimization constraint set and optimization target set, which makes the calculation complex, and the prior art does ...
