This data is the joint survey data of control points from hezhongsizhuang E650 static measurement in June 2012. Through the adjustment of three national control points with landtop2.05 tool, the result solution accuracy is controlled within 2cm, and the data longitude and latitude coordinate system UTM WGS84. Among them, the GPS E650 static measurement was carried out according to the "GPS survey specification" (GB / t18314-2001) and the data from the field survey of "glacier observation and research methods" (Science Press, 2012).
4-6 E650 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
