Problems solved by technology

In practical engineering applications, if the above-mentioned conventional observation path design idea is adopted, during the observation of the target star with a large orbital inclination angle, due to the high normal rendezvous speed of the double star and the short observation time, a large number of target stars miss the effective observation opportunity. Imaging efficiency is low, unable to meet the needs of observation tasks

Abstract

The invention relates to a synchronous orbit star group multi-target observation orbit plane common path design method. The method comprises the following steps: acquiring orbit ephemeris of n target stars of a synchronous orbit star group and an initial orbit ephemeris of an observation satellite; establishing an observation orbital plane common path model of the observation satellite, and forming an objective function model formula of the observation orbital plane common path of the observation satellite through a plurality of observed quantities; establishing a preset iterative algorithm model, and traversing and solving extreme points of the objective function model; setting a threshold value epsilon (1) of a preset iterative algorithm model; and when the extreme point of the objective function model formula is less than or equal to a threshold value epsilon, operation is stopped, and the optimal common path of the observation orbit surface is obtained. According to the embodiment of the invention, one-time orbital plane control is adopted, and an invariable observation plane public path is established, so that node single-satellite multi-batch orbital plane control is avoided while the maximum effective observation of the observation target is met, and the fuel consumption is greatly saved.

Description

technical field [0001] The embodiments of the present disclosure relate to the technical field of satellite observation, and in particular, to a method for designing a common path of an orbital plane for multi-object observation of a constellation constellation in a synchronous orbit. Background technique [0002] The geosynchronous orbital belt (GEO orbital belt for short) refers to a 360° annular belt with a width of 22077km within a range of ±15° inclination near 35785km above the Earth's equator. The dynamic characteristics of the geosynchronous orbital belt endow it with good coverage stability relative to the surface, that is, the satellites in the orbital belt have the same or similar characteristics as the earth's rotation angular velocity, and the satellites in the orbital belt are stationary relative to the ground when viewed from the ground. , so that the satellites arranged in this orbital belt can stare at the fixed area on the ground 24 hours a day without inte...
