Through predicting error of transfixion measurement,constitutes the scheme of reasonable measurement,by using the methods of GPS conjunction and gyrostatic orientation survey and os on,raises the precision of goniometry and ensures the project favorable transfixion.

GPS monitoring on the representative landslides in Danba,Sichuan;

Through GPS monitoring in Shuichang iron mine, the location of monitoring points and the optimizing design of monitoring network were discussed.

The monitoring system configuration, layout of monitoring points, design of monitoring network, satellite position prediction, conversion of coordinates and data processing are discussed in combination with GPS monitoring of slope deformation in Shuichang Iron Mine.

The algorithms are of good application value for GPS attitude determination systems.

The paper introduces the principle of GPS attitude determination,and directly measures vehicle state parameters such as vehicle sideslip angle.

Through analyzing the engineering example, this paper reveals one factor of electric power line’s influencing the GPS measurement: the insulating property of the tripod.

The methods, counter measures and practical results in applications of GPS measurement technique for landslide monitoring, are discussed.

Research on data quality analysis of the GPS monitoring network;

Study on data processing program for GPS monitoring network;
