RTK and Base Station Basics
Real-time kinematic, or RTK, refers to a GPS positioning system comprised of two GPS Receivers with a data link between
them. One GPS Receiver is the on Base Station, which must remain stationary. The other GPS Receiver is on the vehicle,
which can move around. The purpose of the Base Station is to calculate position corrections and transmit them to the vehicle.
The vehicle uses the position corrections to determine its position (and Autosteer) with sub-inch accuracy. It is important that
the Base Station does not move during operation, since the vehicle's position is measured relative to the Base Station’s fixed
position.
•
If you want to continue or repeat a previous job, the Base Station GPS Antenna must be returned to the exact location as
when the job was created. For more information, see Repeatability on page 4.
•
If you need accurate latitude and longitude positions for your vehicle (for example to use mapping functions of the User
Display and/or 3rd party software for boundary creation or variable rate applications), the Base Station’s GPS Antenna
latitude and longitude must be known. For more information, see Accurate Latitude and Longitude Positions on page 5.
•
If repeatability is not needed for your operation, the Base Station's GPS Antenna does not need to be returned to an exact
location. In this case, using the Tripod provided with the Mobile Base Station provides the most flexibility and/or
portability.
