| 摘 要： | 提出了一种针对多遥感器、多数传通道的陆地观测卫星地面接收快视系统设计的新思路，即当星上有效载荷压缩数据与未压缩数据混编下传时，在地面接收站只需从混编基带数据中提取未压缩数据，进行帧同步与去格式处理后实时快视，即可达到既能实时监测数据接收质量，又简化地面接收系统设计的目的。

| Abstract: | This paper puts forward a new idea about the design of ground receiving quicklook system for multi-sensor and multi-channel land observation satellite.When the mixed data compressed and uncompressed are transmitted from the satellite,ground receiving station only needs to separate the uncompressed data from the mixed raw data,and then generates the real time quicklook image after the process of frame synchronization and de-format for uncompressed data.This design idea can not only guide to monitor the data reception quality,but also simplify the design of ground receiving system. |
