RTK Surveying

Real-time differential positioning involves a reference (base) station receiver
computing the satellite range corrections and transmitting them to the remote stations.
The reference station transmits the corrections in real time to the remote receivers via
a telemetry link. Remote receivers apply the corrections to their measured ranges,
using the corrected ranges to compute their position.

RTK (Real-time kinematic) positioning can be used in lieu of real-time differential
positioning. RTK uses the carrier signal in addition to the code signal and is much
more accurate. Although messages transmitted and calculations performed vary, RTK
is essentially a special form of differential positioning. A base station receiver is
required to transmit RTK data to remote receivers. The remote receivers use the RTK
data to compute a corrected position.

As stand-alone, the Z-Surveyor and Z-FX can compute a position to around 15 meters
(100 m with Selective Availability - SA - Set in the satellite). Differential GPS
achieves sub-meter precision at a remote receiver, and RTK positioning achieves
centimeter accuracy at a remote receiver.

A communication link must exist between the base and remote receivers. The
communication link can be a radio link, telephone line, cellular phone,
communications satellite link, or any other medium that can transfer digital data.
