Real Time Kinematic (Rtk) Surveying - Topcon GB-500 Operator's Manual

Introduction
With Stop & Go kinematic surveying, the rover receiver
remains on while moving from one survey point to another.
As a result, the rover's trajectory consists of alternating
static and kinematic occupations. The rover must
continuously track satellites without losing a lock on the
satellites when changing from kinematic to static
observation, and vice versa. With Stop & Go surveying,
static observation time is normally selected between 10 to
60 seconds, while the recording interval is selected so as to
have at least a dozen measurement epochs over the static
occupation. The longer the static observation time, the
greater will be the precision of the data obtained. The
analytical results obtained from this method correspond to
the static observation site.
Continuous kinematic surveying is a non-stop surveying
method used for obtaining the consecutive, precise
trajectory of a moving body, etc. With this method, results
are obtained for each recording interval.

Real Time Kinematic (RTK) Surveying

Real time kinematic (RTK) surveying is a method that returns
positioning results obtained in real time, and requires a
controller to download and save the results.
With RTK surveying, as with post-processing kinematic
surveying, one receiver serves as the reference station and
conducts observation with its antenna anchored using a tripod
or some other device; while the other receiver functions as a
rover and conducts observation using an antenna affixed to a
pole and moved to observation points.
Unlike post-processing kinematic surveying, the reference
station and rover are linked using a radio system or other
communication system. The correction data of the carrier phase
data, etc. obtained through observation at the reference station
1-6
is transmitted to the rover via the modem. The rover, based on
