Application of Global Positioning System in High Accuracy point Determination of Airborne Remote Sensing Data
GPS 全球定位系统在航空遥感精确定位中的应用

The present status and future development about the application of GPS in high accuracy point determination of airborne remote sensing data are briefly summerized. The emphases are to describe the applicability of GPS in airborne remote sensing and to give a typical axperi-ment result of aerotriangulation by using differential phase GPS measurement. Theoretical investigation and practical test show that kinematic GPS technique can be used for topographic and thematic mapping with a scale from 1:500 to 1:100 000, as well as for high accuracy point determination such as coordinate cadastre because it provides very high accuracy and reliability. The prospective applications of GPS technique in airborne and Spaceborne remote sensing are also discussed.
