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2D, FY2E, FY2F and FY2G satellites was realized by using the satellite coorbital and seamless handover technology without service interruption and quality deterioration.
