GPS Real Time Kinematic - RTK GPS

Real time kinematic GPS is a position location process whereby signals received from a reference device (such as a GPS receiver) can be compared using carrier phase corrections transmitted from a reference station to the user’s roving receiver. Using the correction information, RTK systems can provide real time accuracy below 5 cm.

Figure 1.8 shows how a RTK GPS system uses a base GPS receiver to gather and transfer information to a GPS rover receiver. The data from the base receiver can be used by the roaming receiver to calculate more accurate position information in real time (or near real time).
