摘　　要：设计研究了国产高精度POS系统的精度测试方法,通过与POS/AV 610同步集成数字航测相机开展精度测试,对飞行平台进行改装,在满足试验环境一致性的条件下,分别采用直接对比方法与航测成图方法进行精度分析,测试验证国产POS系统的测量精度以及航测成图精度,为国产高精度POS系统的研制与应用提供精度验证手段。试验结果表明,国产POS系统在测量精度方面基本达到POS/AV 610水平,利用国产POS辅助航空摄影,影像分辨率为10 cm时可以满足1∶1 000比例尺成图精度要求。Position and Orientation System（ POS） which is the necessary devices for aerial remote sensing can provide high precision position, speed and attitude information for digital aerial cameras, SAR and Li DAR. In this paper, the method of accuracy verification for homegrown POS systems was researched. The accuracy verification was carried on through the integration of POS / AV 610 with homegrown POS systems on the same flight platform simultaneously. Under the same experimental circumstances, direct comparison and aerial triangulation method were used to verify the precision of homegrown POS systems. The experiment results demonstrate that the precision of homegrown POS systems is the same as that of POS / AV 610. Aerial photogrammetry aided by homegrown POS systems can satisfy the accuracy requirements of 1 ∶ 1 000 scale topographic maps.
