1, RTK, refers to real-time dynamic carrier phase difference technology. This is a new commonly used GPS measurement method, the previous static, fast static and dynamic measurements need to be solved after the fact in order to obtain centimeter-level accuracy, while RTK is able to get centimeter-level positioning accuracy in the field in real time measurement method.
2, it uses the carrier phase dynamic real-time differential method, is a major milestone in the application of GPS, its emergence for engineering sampling, topographic mapping, a variety of control measurements has brought a new dawn, greatly improving the efficiency of field operations.
:In GPS measurement, such as static, fast static and dynamic measurements need to be solved afterward to obtain centimeter-level accuracy, while RTK is a measurement method that can obtain centimeter-level positioning accuracy in the field in real time, and its appearance greatly improves the efficiency of field operations.
