Description
A relative positioning procedure where carrier phase measurements (or
corrections) are sent in real time from a reference or base station to a known
location or to one or more vehicles equipped with a GNSS receiver.
A GNSS receiver that supplies differential corrections to receivers equipped
with GNSS. Also called a base or a reference station.
Name for mobile machines that work with GNSS position data.
Radio Technical Commission for Maritime Services.
Association of base stations that transmit their position data to a server via the
Internet (Ntrip). The vehicles in the RTK network (rovers) also transmit their
position to the server via mobile radio. The server uses the position data from
the base stations and vehicles to calculate the correction data for each vehicle
and transmits it to the vehicle via mobile radio. This allows position
determination to be carried out with an accuracy of 1-2 cm in real time.
The age of the correction measurement values or the time between the
recording and when the measurements are used.
A measurement that specifies how close the estimated GNSS position is to
the actual position.
The unique identification number allocated to the respective GNSS satellite.
The right-angled distance between the current tractor position and the wayline.
The offset of the way line parallel to the original wayline. This is calculated
relative to the waypoints set.
The offset at right angles to the wayline, which shifts the position of the GNSS
aerial relative to the way line; this depends on the direction of travel and may
be set to the right or left.
A positioning service provided by the US Department of Defense for all civilian
GPS users worldwide. This service typically uses the "Coarse Acquisition
Code".
The angle of the tractor relative to the way line (measured in degrees).
OmniSTAR VBS or WAAS.
Teach In: Automatic functions programmed by the driver.
The trigonometric method of determining the position of a fixed point used
two or more fixed points and the distance between them.
The area of the field that is processed more than once during operation.
Ultra High Frequency
The gap between two consecutive tracks on the field.
Very High Frequency
Consists of the components mounted on the tractor for operating the
automatic steering: Steering angle sensors, hydraulic hoses, valve blocks and
brackets.
