Maternal love is a clear spring, let your feelings even though the dust of the years still clear and clear. Overview of the GPS control measurement technical design (reproduced) The purpose of this internship is to understand the whole process of control survey work, master the basic knowledge of GPS static survey data processing, consolidate classroom learning theory knowledge, the organic combination of theory and practice, improve the level of theory and field operation capability. Measure basis, principle CH 2001-92 global positioning system (GPS) measurement specifications CJJ 73-97 global positioning system city measurement technical specification CH 1002-95 inspection and acceptance of surveying and mapping products CH 1003-95 quality assessment criteria for surveying and mapping products CJJ 8-85 urban measurement specifications Technical design of the project Zone situation 2.1 scope and task of measuring area The measurement location Yu Dongjing 108 ° 57 , latitude 34 ° 13 nearby. Located at the east courtyard of chang an university, the north of the survey area is located in the north of yucai road, east to yanta road, which is a teaching area, with flat terrain, buildings and trees, with poor visibility conditions. This internship will set up 7 GPS control points in the survey area and build a d-class GPS network to meet the needs of the internship. 2.2 existing information If you have a known national high grade triangle, you can consider a national high grade point to convert the coordinates of the GPS nodes to the national coordinate system. If there is no known national high grade triangle, the independent coordinate system is adopted. 2.3 control network data The practice of GPS control network can consider using national grade point 2, national grade point must have xian coordinate system 1980 or
