This data set is for Gongga mountain area. The global position system (GPS) control point joint measurement data set includes the serial number, longitude, latitude and elevation of the control point. The data set contains 60 records, mainly through the purchase of the national level 1 control points in the region, the use of national level 1 control points for static measurement, synchronous measurement time more than 1 hour, through the solution to obtain the glacier area control points; through dynamic differential GPS dynamic joint measurement to obtain. 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.
Mainly through the purchase of national level control points in the region, the global position system (GPS) of Trimble 5800 is used to measure the time synchronously for more than 1 hour, and through Trimble geometry office The control points in the glacier area are obtained by solving with the software, and then the dynamic joint measurement is obtained by dynamic differential GPS. The dynamic differential GPS measurement process is standardized and standardized, and strictly rechecked.
The joint measurement is carried out by using X20 or T5 GNSS of 4-6 Taihua survey, the synchronous measurement time is more than 1 hour, and the joint measurement is carried out by using 1-3 national level control points; the result solution accuracy is controlled within 2cm
