9.1.1 Glossary
Designation Description
Activated status The status in which automatic steering is switched on and controls the
steering movements of the tractor. The status display is green when automatic
steering is in activated status.
Pass-to-pass accuracy The relative accuracy from one wayline to the next, which is carried out within
15 minutes on consecutive runs. Can be two to five times more accurate than
static accuracy.
Aerial offset The distance between the aerial and the middle of the tractor.
ASCOS Satellite positioning service in Germany.
AutoTI Automatic functions, programmed by the driver, start depending on the
tractor's position with regard to the headland boundary.
Base station A GNSS receiver that supplies differential corrections to receivers equipped
with GNSS. Also called a base or a reference station.
Baud rate Data transmission speed in bits per second (bits/s).
Latitude The distance north or south of the equator, measured in degrees. One minute
of latitude equates to one nautical mile (1852 m). The equator has a latitude of
zero.
Circular Error Probability
(CEP)
A static measurement of the horizontal accuracy measuring the radius of a
circle, in relation to the center point of the actual position within which the
position solutions lie. A CEP measurement of 50% shows that half of the
measured position solutions lie within the radius of accuracy.
Controlled Traffic
Farming (CTF)
A method of agriculture that uses permanent tram lines and beds for all
agricultural applications. All implements must have the same width or a
multiple thereof.
Decimetre accuracy
(DM)
Accuracy of up to +/- 5 centimeters, ensured by DGPS options such as RT20.
Differential GPS (DGPS) A method that uses correction data from satellite services or fixed reference
stations to increase GPS accuracy. The satellites or local reference stations
send correction data to vehicles equipped with GNSS receivers.
Differential YAW (DYAW) The relative speed, measured in degrees per second, at which the center point
of the measurement moves from its intended direction along the horizontal
plane.
Dilution of Precision
(DOP)
A measurement of the proportion of the satellite geometry with respect to the
inaccuracy of the position determination.
Dual frequency Instrumentation with the capability of carrying out measurements on both L
bands. As a result, changes in carrier range or ionospheric adjustments can be
carried out in real time. A dual-frequency GNSS receiver is more accurate than
a single-frequency GNSS receiver, which can only use the first L band.
EGNOS European Geostationary Navigation Overlay Service, sub-meter (SM) accuracy.
Free European Differential Global Positioning System (DGPS).
