The invention discloses a satellite-borne real-time visual telemetering system, and belongs to the field of image data processing and transmission. According to the satellite-borne real-time visual telemetering system, in-orbit compressed image data is adopted, health states such as satellite-rocket separation, solar wing sailboard unfolding and data transmission antenna unfolding of a satellite are monitored in real time in a measurement and control channel issuing mode, and successful launching of the satellite is assisted; according to the method, the full life cycle of the satellite can be covered, and a direct qualitative conclusion can be given when an abnormality occurs; an image compression technology is adopted, the compression ratio reaches 1/87, compressed data are decompressed and restored on the ground, and a large amount of satellite-ground bandwidth is saved.

    本发明公开了一种星载实时可视化遥测系统,属于图像数据处理及传输领域。本发明的星载实时可视化遥测系统,采用在轨压缩图像数据,通过测控通道下发的方式,对卫星的星箭分离、太阳翼帆板展开及数传天线展开等健康状态实时监控,助力卫星成功发射;本发明不仅能覆盖卫星的全生命周期,且在发生异常时给出直接定性的结论;本发明采用图像压缩技术,压缩比到达1/87,压缩后的数据在地面解压缩还原,节省了大量星地带宽。
