Principle and Method of Airborne Remote Sensing Direct Geo-referencing Using GPS/IMU
Pages: 11-14
Year: Issue:  2
Journal: Hydrographic Surveying and Charting

Abstract: 阐述了GPS/IMU系统进行位置与姿态测量的基本原理,推导了利用GPS/IMU的导航解计算遥感器瞬时外方位元素的数学模型,并利用机载三线阵影像验证了GPS/IMU辅助直接对地定位的精度潜力.三组ADS40数据直接定位的试验结果表明,GPS/IMU提供的外方位元素具有较高的定位精度,平面精度优于2.5个像元,高程优于5.1个像元,但存在系统性的测量误差,在大比例尺遥感测绘作业中引入少量控制点参与平差...
