摘要
本文在分析了GPS相对定位及其RTK在像控中应用的优缺点后,提出了精密单点定位进行像控测量的方法。通过实例证明这种方案是完全可行的,并得出了一些对生产实际有益的结论。
After analyzing the merits and demerits of GPS relative positioning and RTK technology used in photocontrol points surveying, this paper puts forwent a new method which is GPS precise point positioning using un- differenced phase. The feasibility and effectivity are proved by example, and some conclusions, which are useful to practice, are drawn.
