山区测区 GPS 点的高程异常推估方法研究

Research on the method of estimation of height anomaly of GPS points in mountainous areas

用ＧＰＳ测量技术能否直接建立山区测区的高程控制，关键在于能否精确获得各ＧＰＳ点的高程异常．本文介绍了利用ＧＰＳ水准观测资料，采用最小二乘配置法，推估山区测区各ＧＰＳ点的高程异常的理论与方法．

The key of applying GPS surveying technique to the set up of the height control in mountainous areas lies in calculating accurately the height anomaly of each GPS point. The theory and method of estiimating the height anomaly of each GPS point in mountainous area by applying GPS level observation data and adopting least squares collocationis is introduced.
