SPOT卫星的数据捕获与处理是由两个不同的系统承担的: 空间图象数据接收站(SRIS)主要职能是用X波段接收SPOT卫星或美国陆地卫星传输的遥测数据(SPOT卫星地面站在设计上是与美国陆地卫星兼容的),放大、解调并将它们记录在高密度磁带(HDDT)上。此外还进行信号的适时显示,捕获卫星飞过天顶轨道时的数据。为了方便地面站的各种操作,还将设置各种测试设备:准直天线、超高频和视频发生器。空间图象校正中心(CRIS)接收SRIS站传输来的数据,并进行尺寸定型,录入磁带;校正由于星上仪器和照相条件造成的辐射测量误差和几何测量误差,这些工
Data acquisition and processing of SPOT satellites is undertaken by two different systems: The primary function of the SRIS is to receive telemetry data from SPOT satellites or US terrestrial satellites in X-band (SPOT satellite ground stations are designed Is compatible with US terrestrial satellites), amplified, demodulated, and recorded on high-density tape (HDDT). In addition, timely signal display, capture the data when the satellite flew over the zenith track. In order to facilitate a variety of ground station operations, will also set up a variety of test equipment: collimation antenna, UHF and video generator. The Space Image Correction Center (CRIS) receives data from SRIS stations and sizes them for tape entry; corrects for radiometric and geometric measurement errors due to on-board instrumentation and photographic conditions,
