| 摘 要： | 指出GPS大地高与正常高之间的转换关系较难确定是限制GPS高程应用的主要原因。为此，在长期研究和实践的基础上，提出了在一定条件下，利用GPS精密高差测量技术完全可以象水准测量一样高精度获取正常高高差，进而获得正常高的观点。并讨论了利用GPS技术进行精密高差测量的技术方案及具体方法，给出了相应的工程实例。

| Abstract: | It is more difficult to confirm the transformation relationship between geodetic height and normal height. This is main reason of restricting application of GPS height into use. Based on the basis of research and practical for long period, this article brings forward the method to get normal height difference by means of GPS precise height difference which is up to leveling precise, and then gets normal height. The article discusses the technical scheme for GPS precise height difference and special measurements, and last gives a relevant engineering example. |
