摘要
分析影响陆地遥感卫星影像获取的主要因素,针对卫星数据星地接收瓶颈问题,提出基于天基中继的卫星影像数据传输应用模式。仿真分析和量化测算中继传输的应用效果,结果表明中继传输可以提高卫星数据接收可视时长,从而极大提升影像数据获取总量,有效发挥卫星运行效能。
With the analysis of the main factors aff ecting the image acquisition of land remote sensing satellite,the satellite image data transmission application mode based on space-based relay was proposed to solve the bottleneck problem of satellite-ground receiving.Through simulation analysis and quantitative calculation,the application eff ect of relay transmission was calculated.The results showed that relay transmission could improved the visible time of satellite data receiving,thus greatly improved the total amount of image acquisition,and eff ectived perform the satellite operation effi ciency.
