Description
Electrohydraulic steering.
Defined working area of the tractor.
The edge of the field.
A computer program that is permanently embedded in the hardware of a
device.
Mapping the processed area.
The level of concordance between the measured and the actual position.
The dilution of precision, which is associated with the geometric effects of the
satellite position.
A constant, fixed position above a certain reference point on the surface of the
earth.
Working width of the tractor or the agricultural implement.
The change in direction observed when the steering wheel is moved.
Adapts the contour guide if sharp bends occur on waylines determined from
the original track.
Satellite navigation system operated by the Ministry of Defense of the Russian
Federation.
Global Navigation Satellite System. System for position determination and
navigation on land and in the air using satellite signals and signals received
from pseudolites.
General Packet Radio Service. Packet-oriented service for transmission of data
in GSM and UMTS networks.
Global Positioning System. North American NAVSTAR satellite navigation
system.
Global System for Mobile Communications. Standard for all-digital mobile
communications networks. Mainly designed for telephony, but also for packet-
oriented data transmission and short messages.
The ionosphere is a layer of charged particles over the surface of the earth. An
ionospheric error is an error that is caused by the attenuation of GNSS signals
as they pass through the ionosphere. Ionospheric errors are at their highest
during the day and at their lowest during the night.
Inertial Measurement Unit: Provides information about the yaw and roll of the
vehicle.
A graphic display on the terminal, which shows the position of the tractor, the
target wayline, way line distance, correction signal info, steering status, area
marker, marker, obstacles and boundaries.
The position determination during motion.
The convergence time is the time required by the software to determine the
position of the tractor after the system is switched on.
