Transmitting and Receiving Corrections

Corrections can be transmitted from a base station to a rover station to improve position accuracy. The
base station is the GNSS receiver that acts as the stationary reference. The stationary reference has a
known position and transmits correction messages to the rover station. The rover station is the GNSS
receiver that does not know its exact position and requires correction messages from a base station to
calculate differential GNSS positions. An example of a differential setup is shown in Figure 18.
