摘要: 分析了偏流角改正和偏流角余差对卫星三线阵CCD影像摄影和控制定位的影响,提出了在卫星三线阵影像控制定位计算中消除偏流角余差影响的方法。实验结果表明,偏流角余差对卫星三线阵CCD影像控制定位的影响很大,在实际应用中必须加以修正。Abstract: The impact both satellite three\|line array CCD and control geopositioning because of drift angle correction and residual drift angle is analyzed.The method that eliminates impact of residual drift angle in the control geopositioning of satellite three\|line array CCD is proposed. The experimental result shows that the control geopositioning of satellite three\|line CCD has great impact because of residual drift angle. It must be corrected in practical applications.
