DGNSSRTK
DGNSSRTK, short for differential GNSS real-time kinematic, refers to a positioning approach that combines differential GNSS corrections with real-time kinematic processing to achieve high-accuracy positioning. In this method, corrections generated by reference stations—either a single base station or a network of stations—are provided to a rover user in real time. These corrections help mitigate satellite clock errors, orbital errors, and, to some extent, atmospheric delays, improving the quality of the raw GNSS observations.
The corrections are transmitted through real-time communication links such as radio, cellular networks, or internet protocols
Accuracy and performance of DGNSSRTK depend on several factors, including the geometry of satellites, baseline length
Limitations include the need for reliable communication links, potential latency, and coverage gaps in sparse networks.
