Base Station Configuration
For RTK reference station (fixed base station), the antenna is placed at a fixed
place, and won’t move.
The precise coordinates of the known point and the satellite information received
are sent to the rover station receiver (the undetermined point), the rover station
receiver also receives the base station information and the satellite observations, then,
performs RTK solution to achieve the centimeter level or millimeter level accuracy
positioning. Frequently commands used to configure the RTK base station are as
follows.
When the precise coordinate is known, input the following commands to the
receiver:
