摘要
该文根据多年的ＧＰＳ测量实践，建立了局部高程异常的基本几何模型，并提出了利用高程异常几何模型将ＧＰＳ高程转化为正常高的新方法。
Based on the practice of GPS surveying for many years, the paper establishes the basic geometric model of local elevation abnormality. Also, it presents a new method to transform the GPS height to normal height using the geometric model of elevation abnormality.
