山区测区GPS网正常高求解方法的研究

Research on the Method of Evaluation of GPS Network Normal Height in Mountainous Areas

若不辅助其它技术与手段，ＧＰＳ观测高程信息是无法直接应用于区域性工程高程控制测量的．本文提出了在山区测区条件下，利用ＧＰＳ水准结合天顶距观测（计算垂线偏差）直接确定高程异常，进而求解ＧＰＳ网正常高的理论与方法，具有良好的技术与实践价值．

Without the aid of other techniques and means, GPS surveying height information cant be applied directly to the regional engineering vertical control survey. The author of this treatise puts forward the theory and method of determining the height anomaly and evaluating GPS network normal height by combining GPS level with zenith distance observation (calculating the deflection of the vertical). This treatise has good technical and practical value.
