德国卫星定位与导航服务计划刘经南闵宜仁张燕平汤海（续上期）２．差分服务体系的数据发送传输系统德国差分ＧＰＳ服务系统的一大特点是：数据发送传输系统（数据链）是综合性的，包含了多种发送手段。在数据传输率、抗干扰和作用半径等方面各有特点、互相补充，为用户提...
Based on the theory of statistical correlation and the research results of the propagation of the error and the estimation of accuracy, the allowable error of the total means square error per kilometer and the quality control in precision leveling is investigated in the paper. The unbiased formula of the total mean square error is also given in light of the figure correlation.
