风云二号气象卫星双星共轨技术研究与应用

Research and Application of Two Satellite Co-orbital Technology for FY-2 Meteorological Satellites

卫星空间位置部署调整过程中,新旧卫星业务的切换期间,卫星观测业务服务的暂停是不可避免的。随着气象卫星应用范围的扩大和服务需求的增多,卫星布局调整过程中保证业务服务不中断、业务质量不降低成为卫星业务管理的迫切需求。根据风云二号卫星和地面应用系统的业务体系和技术特点,研究了双星共轨工作的技术条件和业务影响,提出利用双星共轨技术实现新旧卫星更替时业务无缝切换的方案。采用双星共轨技术和业务无缝切换方法实现了风云二号卫星D、E、F、G的业务布局调整,达到了卫星业务不中断、业务质量不降低的目标。

Generally speaking,satellite observation service will be suspended for satellite operation handoff during satellite orbit readjusting.With the expansion of meteorological satellite application and the growing demand for meteorological satellite service,how to ensure continuity and stability of operational services in the satellite orbit position adjustment period has become an urgent demand.This paper studies the technical specification and effect on the operation of two satellite co-orbital technology based on the framework and characteristics of the FY-2 satellite and ground application system.A scheme using two satellite co-orbital technology for operational seamless handover is proposed.The orbit readjusting project of FY-2 D,FY-2 E,FY-2 Fand FY-2 Gsatellites was realized by using the satellite co-orbital and seamless handover technology without service interruption and quality deterioration.
