X20R (RTD) is HuaCe innovated Real-time differential GPS Receiver Surveying System. It is providing the sub-meter surveying accuracy in the precision positioning, dredging, channel measurement, attitude deformation of the high-speed ships and other related works.

The radio datalink of X20R is specially designed, which is able to detect the interference sources. Under the multi-path interference environment and radio signal jamming place, such as port, construction area, the X20R can still perform very well.
