The RTK Base
The main purpose of the base is to provide a known position to the RTK system in order for the RTKLib to compute the exact position of the rover module. It's then necessary to have a base whose position doesn't vary in time, and with the most accurate self-positioning ability. The base station accuracy is achieved by Survey-In which respects the computation between a successful minimum observation time and the required position accuracy chosen by the user. The more accurate the base positioning, the more accurate will be the rover module positioning. Thank you for the RTK methodology. The positioning accuracy evolves to nearly 1-2cm accuracy.
