3.3 Transmitting and Receiving Corrections
Corrections can be transmitted from a base station to a rover station to improve position accur-
acy. 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 dif-
ferential setup is shown in Figure 15: Basic Differential Setup below.
