This data set is for the main peak area of Nianqing Tanggula Mountain, mainly including karigan glacier, the main peak of Nianqing Tanggula Mountain. The GPS control point joint measurement data set includes the serial number, longitude, latitude and elevation of the control point. The data set contains 19 records, which are mainly obtained by purchasing the national level 1 control points in the region, using the national level 1 control points for static measurement, synchronous measurement time of more than 1 hour, obtaining the glacier area control points through solution, and dynamic joint measurement through DGPS RTK. The data set is only aimed at the elevation of the glacier surface in 2015, so it is not supplemented and fully open for sharing. Data set longitude, unit degree (°), latitude, unit degree (°), elevation, that is, the elevation of glacier surface in the current year, unit meter (m).

This data set is mainly the measured data, and the data mainly comes from the static measurement of national first level control points and the dynamic joint measurement of DGPS RTK.
Through purchasing the national first-class control points in the region, the global positioning system (GPS) of Huace T5 model is used for synchronous measurement for more than 1 hour, and the control points in the glacier area are obtained through the solution of hCG software; then the dynamic differential GPS is used to obtain the dynamic joint measurement, and the dynamic differential GPS measurement process is standardized and standardized, and strictly reviewed.
4-6 stations of China Survey X20 or T5 GNSS are used for joint survey, the synchronous measurement time is more than 1 hour, and 1-3 national control points are used for joint survey; the result calculation accuracy is controlled within 2cm
