Field measurement data in 2013.
Taking one Huace T5 GNSS as the base station and two Huace T5 GNSS instruments as mobile stations, the field survey of landmark features (Road intersection, bridges, boulders, buildings and other corner points) in Animaqing area is generated. The survey software is the LandStar manual software of China survey. CGCs 2000 is the target coordinate system and 99 ° is the central longitude. The point coordinate calculation is completed by LandStar software in real time. Only the points with fixed solutions (plane coordinate error & lt; 3cm, elevation coordinate error & lt; 4cm) are selected, and the measurement time is 10 seconds. In the measurement process, three point coordinates determined in the previous static survey are used for point correction to ensure that the measurement results are consistent with the static measurement coordinate system.
4-6 stations of China Survey X20 or T5 GNSS 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
