Design of Control Quantity Optimization Algorithm under Customized Holding Loop Constraints
In response to the demand for automatic and rapid calculation of control strategies for maintai-ning the trajectory of a large number of satellites,research is implemented for the optimization design of sat-ellite orbit control quantity calculation under the customized maintenance loop indicators.The optimization algorithm for satellite orbit control variables under customized maintenance loop indicators is studied.On the basis of analyzing the characteristics of the regression orbit,the calculation method of the reference benchmark for trajectory network prediction is optimized.Pseudo observation data is obtained by using his-torical precision ephemeris,and the average atmospheric damping coefficient is calculated as input for the trajectory network precision prediction model.An automatic calculation method for trajectory control quantity based on iterative correction is designed,which accelerates the search speed by reasonably selecting initial values,adjusting the coarse screening interval of control quantity and setting iteration termination thresh-olds.The simulation results show that this the automatic calculation of control variables for satellite trajecto-ries that reaches the specified western boundary can be quickly completed by using this method which provides theoretical support for the automatic calculation of routine orbit control strategies for a large number of satel-lites in thefuture.
