Survey
The reference station obtains accurate location information through long-term observation and transmits the observation data to the control center in real time through the data communication system. The control center calculates the error correction parameters in the area and then sends the error information to the rover (user terminal) through ground-based augmentation system, wide-area augmentation system, satellite-based augmentation system, etc. Through RTK real-time dynamic measurement technology, the user finally obtains accurate coordinate information, empowering measurement and mapping applications.
