摘　　要：根据RS编译码原理,结合高分辨率遥感卫星在轨影像实际数据压缩情况,提出将RS(255,243)和RS(34,26)两种编码算法进行联合使用的方案,以解决数据传输中误码问题,仿真试验证明该方法在解决有干扰条件下的星地数据传输时,可有效防止和减少误码扩散。According to the principle of the RS code and encode, as well as the actual compressing effect of high-resolution remote sensing satellites, a scheme using RS（255,243） and RS（34,26） is proposed to satisfy the requirement of high-resolution remote sensing satellite data transmission. The emulation experiments show that the method is effective for the data transmission between satellite and the earth under interference condition, and it can prevent and reduce the error diffusion.
