Embodiment Construction

[0031] When a single star enters the formation, with two impulses v 1 , v 2 The required energy consumption is taken as the performance index J, and the scheme with the smallest energy consumption is selected as the scheme for entering the formation around the star, J=min{||v 1 ||+||v 2 ||}

[0032] In the asynchronous establishment strategy of the formation, the time for each orbiting star to leave the initial point is different, the time to arrive at the rendezvous point of the relative orbit is different, and the transfer time is not necessarily the same. Therefore, according to the order in which the orbiting stars enter the formation, the initial position and initial velocity of each orbiting star and the phase when entering the formation must be calculated separately, and then the energy consumption is calculated according to the method of a single orbiting star entering the formation. The sum of energy consumption is the total energy consumption of formation establis...

Abstract

A method for optimizing the consumption of a micro-satellite group formation, which mainly includes the following steps: determining the factors related to the satellite orbit transfer time and fuel consumption as the transfer time and the terminal position; determining the inter-satellite coding structure in the satellite group; forming the satellite orbit transfer energy consumption calculation method; the niche genetic algorithm analysis is carried out on the energy consumption of the formed satellite orbit change transfer, and the optimal orbit change energy consumption data is formed, which is converted into the corresponding dual-pulse engine energy consumption control parameters. The invention combines niche technology and genetic algorithm, takes energy consumption as the optimization target, and is applicable to the situations of a single orbiting satellite, synchronous establishment of multi-satellite formation, and formation of multi-satellite asynchronous formation, and the algorithm has no requirement for the release location of the satellite group, and can Enhanced flexibility for release of microsatellite constellations. It not only retains the advantages of strong robustness, global search and parallelism of genetic algorithm, but also overcomes the disadvantage of poor local search ability of genetic algorithm.

Description

technical field [0001] The invention relates to a space attitude control method, in particular to an energy control method for satellite release and positioning. Background technique [0002] In the establishment process of the micro-satellite formation, the usual method is to release the orbiting star from the reference point to form a flying formation. The space platform releases the orbiting star from the designated location to form a formation, which will increase the flexibility of the mission. However, satellite formation is a process of establishing the space attitude of a satellite group rather than a single satellite. When the release location has been designated and the formation formation strategy has been determined, it is also necessary to optimize the consumption required in the process of establishing the formation of the micro-satellite group, such as energy consumption, time consumption, and so on. Due to the limited platform, the energy carried by microsat...
