摘要
Abstract
Unlike traditional satellite that completes orbit transfer and propelling within a few days using chemical fuel,all-electric propulsion satellite needs to conduct orbit transfer through elec-tric propulsion for several months in the transfer orbit to reduce the transportation cost.As the orbit rises,the continuously immeasurable and uncontrollable arc segment keeps growing,ma-king it increasingly difficult for the ground to handle faults.Therefore,a higher level of autono-mous time management capability is required.To address the characteristics of all-electric pro-pulsion communications satellite-low cost,high autonomy,and high reliability-a time ma-nagement scheme based on autonomous statistical local clock offset and compensation is pro-posed.The scheme can satisfy the satellite's regular time calibration needs and,when the global navigation satellite system(GNSS)time source is unavailable,can autonomously correct clock precision error through autonomous uniform time calibration algorithm,thereby improving the satellite's time accuracy.Simulation results and on-orbit application verification of the APSTAR-6E satellite,demonstrate that the autonomous clock correction time management scheme pro-vides a reliable solution and experience reference for other satellites with high autonomy requirements.关键词
