摘要
针对桥梁GPS高程控制网两岸高程基准的不一致性问题 ,采用了外推法、解系统差参数、高程异常差拟合三种方法对GPS高程进行处理 ,对各种方法进行了分析和比较 ,并采用某线路控制网模拟桥梁GPS高程控制网进行实例分析 。
Three handling methods are applied on differ in consistency of both sides of bridge of GPS height network. The methods are analysed and compared by means of the example that a route control network is simulated bridge GPS height network. An optimal schema of applying height anomaly difference fitting is gotten.
