Abstract

Mapping control survey for 13 control reference points were carried out based on RTK technology using GPS/BEIDOU/GLONASS multi-constellation compatible GNSS receivers in various urban environment (open, building shelter, tree shading, etc.). Operation scheme and technique flow were discussed. Operation efficiency and positioning accuracy in different environment were analyzed. Experimental results show that the horizontal position and elevation of the points measured by RTK can reach 2cm and 3cm precision level respectively in open environment, which can meet the accuracy requirements for mapping horizontal and vertical control survey. However in environment such as building shelter or tree shading, the horizontal position of the points measured by RTK can reach 2cm precision level generally, while the elevation biases are more than 3cm mostly, which is difficult to achieve the accuracy of elevation mapping control survey.
