差分GPS无人机航测技术测试及分析

Test and Analysis of Differential GPS UAV Aerial Survey Technology

伴随当前差分GPS技术的出现,RDA辅助空三已经逐步从实验转变为大规模使用,这也是当前低空航测技术快速突破的一个信号,其操作基地在差分RDA能够对航空摄影时刻摄影中心的空间位置进行准确的获取,并且以此为基础纳入到区域网平差的计算当中,可以让地面控制点大幅度的减少,本文重点对差分GPS无人机航测技术测试进行分析和研究,以供参考。

With the advent of the current differential GPS technology, RDA-assisted air three has gradually changed from experimental to large-scale use. This is also a signal for the rapid breakthrough of low-altitude aerial survey technology. Its operating base is able to accurately obtain the spatial position of the aerial photography time photography center in the differential RDA, and based on this, it is included in the calculation of the regional network adjustment, which can greatly reduce ground control points. This paper focuses on the analysis and research of differential GPS drone aerial survey technology test for reference.
