摘　　要：卫星影像定位精度的验证是支撑卫星业务化运行和应用的基础性工作。为验证高分一号卫星全色影像几何定位精度,实验以天津市北辰区为研究区,测试了高分一号卫星PMS相机全色(PAN)1A级产品的的无控定位精度和带控定位精度。实验结果表明,PAN1影像的平均无控定位精度和带控定位精度分别为27.48 m和2.26 m;PAN2影像的平均无控定位精度和带控定位精度分别为32.63 m和2.35 m。The verification of satellite image positioning accuracy is a fundamental work supporting the commercial operation and application of satellites.In order to verify the geometric positioning accuracy of the panchromatic images of GF-1 satellite,the experiment takes Beichen district of Tianjin as the research area and verifies the positioning accuracy without ground control points and positioning accuracy with ground control points of the panchromatic(PAN)1A product of GF-1 satellite PMS camera.The experimental results show that the average positioning accuracy without ground control points and positioning accuracy with ground control points of PAN1 images are 27.48 m and 2.26 m,respectively;the average positioning accuracy without ground control points and positioning accuracy with ground control points of PAN2 images are 32.63 m and 2.35 m,respectively.
