    Abstract
  • Based on the engineering practice of a certain area, multi-mode global navigation satellite system (Global Navigation Satellite System, GNSS) rapid control and measurement of different constellation were conducted combined positioning analysis, and China's Beidou Navigation Satellite System could obtain position information quickly and accurate in a special environment. Based on the refined fusion technology of multi-mode GNSS-RTK and quasi-geoid, the efficiency of road surface corner measurement could be greatly improved. The accuracy and ergonomics of the vehicle-mounted GNSS-RTK topographic measurement are studied and evaluated in the flat area, and the key quality control points in implementation process is proposed. The costs of field surveying and mapping could be saved and the efficiency could be improved.
