摘要
介绍了GPS水准的原理、公式及实现的途径 ,重点讨论了利用高精度的GPS水准点 ,结合精密水准测量资料 ,推求任意一个计算点高程异常的原理和实现方法 ,建立了以系统转换方法为依据的数学模型 ,有效地解决了两种系统缺少重合点这一问题 。
The paper introduces the theory of GPS-leveling,formula and the way of realization.It emphasizes discussing the theory and realization of calculating height anomaly by way of GPS leveling and precision level-surveying data,so does buildingthe system transformation model,solving the problem of being short of replicatedata between two systems.The example shows that the effect of using system transformation for calculating height anomaly is effective and the model can improve the precision of pre-existing height anomaly.
