| 摘 要： | 首先介绍了GPS辅助空中兰角测量；然后以实际生产项目为例，对无控制、稀少控制、密集控制等不同地面控制条件下的GPS辅助空中曼角测量精度进行了对比分析：同时就构架航线对区域网平差精度的影响进行了试验研究。结果表明，稀少控制联合GPS进行区域网平差是可行的，构架航线有助于粗差探测，并能进一步减少控制点的数量。

| Abstract: | This paper introduces GPS auxiliary aerial triangulation at first. Then taking practical production project as an example, it compares and analyzes tile accuracy of aerial triangulation under different conditions of ground control, such as no control, scarce control, and dense control. Further,nore, it tests and studies the accuracy effects of aerial triangulation by frame flight courses. The results show that the area adjustmeut by a few GCPs together with GPS is practicable. The frame flight courses can contribute to detect gross error, and reduce the number of GCPs further. |
