摘　　要：基于对广州气象卫星地面站风云三号（FY-3）极轨卫星接收系统的深入研究,实现了FY-3接收系统对美国新一代极轨卫星Suomi NPP（National Polar-orbiting Partnership）直接广播数据的兼容接收。给出了FY-3接收系统兼容接收NPOESS（National Polar-orbiting Operational Environmental Satellite System）卫星的具体方案,重新开发了卫星数据进机分包模块,并将方案成功应用于乌鲁木齐和佳木斯气象卫星地面站。针对卫星数据应用需求,详述了RT-STPS（Real-Time Software Telemetry Processing System）原始遥测数据分包和IPOPP（International Polar Orbiter Processing Package）数据预处理流程,完成了NPP卫星数据L0~L1级的预处理。Guangzhou meteorological satellite ground station upgraded the receiving system of the polar orbit satellite of FY-3.It helps the receiving system of FY-3to have the ability to receive the broadcast data from the Suomi NPP satellite of USA.The capacity for receiving of the existing operational system at the Guangzhou ground station is evaluated.A retrofit project of NPOESS（National Polar-orbiting Operational Environmental Satellite System）data reception is put forward.The data acquisition subcontract subsystem is rebuilt.The NPP Receive Scheme is successfully applied in Urumqi and Jiamusi meteorological satellite ground stations.An introduction to the RT-STPS and IPOPP is given.The processing of NPP data is completed from Level-0to Level-1.
