嫦娥一号绕月探测器轨道投入过程实时监测判定的原理与技术实现
Real Time Monitoring the Orbit Insertion of Chang'E-1 Lunar Mission
摘要
Abstract
China's first lunar satellite Chang'E-1 (CE-1) was launched on Oct.24, 2007.During its flight to the Moon, a series of maneuvers were performed to keep the satellite in the correct trajectory.Among these maneuvers, the one performed for Lunar Orbit Insertion (LOI) was the most important part since it directly decided whether the satellite could enter the mission orbit or not.Therefore,real time monitoring and estimation of the satellite's state during this stage became crucial.A system was develop for LOI monitoring using as few data as possible.This system included real time data transmission as well as real time data analysis which could provide the difference between the predicted and observed measurements in the first place, and then, most importantly, it also gives the ensuing orbit insertion conditions, i.e.predicts probable future orbit parameters after the maneuver.The presented method was successfully applied for the LOI process in the mission phase.关键词
