Basics of RTK Surveying

RTK (Real-Time Kinematic) is a GPS system that
yields very accurate 3D position fixes immediately in
real-time.

A reference station (base station) transmits its GPS
position to roving receivers as the receiver generates
them. The roving receivers use the reference station
readings to differentially correct their own positions.
Accuracies of a few centimeters in all three
dimensions are possible. RTK requires dual
frequency GPS receivers and high speed radio
modems.
