RTK (Real-time kinematic) refers to real-time dynamic measurement, also known as carrier phase differential positioning, which is a kind of GNSS relative positioning technology, which can provide the three-dimensional coordinates of the observation point in real time and achieve centimeter-level high accuracy.

Make full use of the current Internet of Things technology, intelligent sensing technology, cloud computing technology, embedded technology, communication and multimedia information technology, independent research and development equipment and application software system as the core, and provide a set of reliable, practical and professional geological disaster monitoring and early warning system solutions for provincial, municipal and county land and resources departments.

The time synchronization of the system is very important for many key infrastructures related to national economic and social security, and the effective operation of communication systems, power systems, and financial systems all depend on high-precision time synchronization.
