Abstract

A long-term evolution rapid analysis method for an inclined geosynchronous orbit comprises the following steps: firstly, deducing a primary or secondary average perturbation force function of each perturbation item, including 1:1 resonance parts of earth non-spherical perturbation field harmonic items J22, J31, J32, J33, J41, J42, J43 and J44 with harmonic items, sun-moon gravitation perturbationLegendre expansion intercepting 4-order items and solar light pressure perturbation; secondly, establishing a secondary average semi-analytical orbit recursor of the IGSO orbit through a Lagrange typeorbit perturbation equation in combination with an average perturbation force function; comparing and analyzing IGSO orbit long-term evolution conditions under consideration of different perturbationsources and orders, so that the model is simplified, and the orbit recursion efficiency is further improved; and finally, by means of efficient orbit recursion, drawing a series of dynamic grid diagrams of complete orbit elements and initial epoch moment combinations, wherein the divisible orbit elements are (e, i, [Omega], [omega]), all binary combinations of the divisible orbit elements are e-i, [omega]-[Omega];e-[omega], i-[Omega], e-[Omega], i-[omega], all binary combinations of the initial epoch moment are InitialEpoch-e, InitialEpoch-i, InitialEpoch-[Omega], and InitialEpoch-[omega], and rapid and comprehensive analysis of IGSO orbit long-term evolution is completed according to the dynamic grid chart.

Description

technical field [0001] The invention relates to a long-term evolution fast analysis method of an inclined geosynchronous orbit, in particular to a spacecraft orbit semi-analytic recursion and dynamic grid diagram analysis method, and belongs to the field of spacecraft orbit dynamics. Background technique [0002] Inclined geosynchronous orbit (IGSO) has important application value in satellite communication and satellite navigation. The long-term evolution analysis of the IGSO orbit provides important information for the mission design and mission post-processing of the corresponding satellites, and the rapidity of the long-term evolution analysis helps to provide more information and is conducive to the rapid iteration of mission design. In the long-term evolution analysis of the earth satellite orbit, it is an effective means to use the semi-analytical orbit recurrence method to draw the corresponding dynamic grid diagram.
