摘　　要：分析了影响传输型立体测绘卫星影像定位精度的误差源,建立了星地误差仿真与评估模型,进行了星地链路误差仿真计算。实践表明:利用星地全链路误差仿真与评估数学模型可以实现星地误差链路的定量分析,为卫星系统指标论证和研制提供技术支撑。The errors which influence the positioning precision of transmission stereo satellite imagery were analyzed, the simulation and evaluation models to analyse the errors from star to ground were established, then the error link from star to ground was simulated. The experimental results showed that the simulation and evaluation models can analyse the link error from star to ground and offer the technical support for the index demonstrating and development of the satellite system.
