ADVANCED SETUP "TRACTOR"
10.2 Tractor
The tractor setup depends on the selected basic settings (chap. 9), which affect which items are displayed in Fig. 76.

10.2.1 DGPS
Fig. 77
Allows to enable / disable the DGPS (SBAS) differential correction function
(
DGPS correction enabled / DGPS correction disabled).
The SBAS differential correction signal is free of charge and available only in some areas of the world.
This signal allows to obtain a more accurate spraying.
WARNING: this function may be used only in Europe (EGNOS), the United States (WAAS)
and Japan (MSAS).
10.2.2 PDOP alarm
Fig. 78
"PDOP" is the parameter that depends on the position and number of satellites in space that affect the
positional precision of the system (longitude and latitude); the lower the value, the higher is the driving
precision.
The precision alarm is triggered when the value of PDOP measured by the GPS receiver is above the
set limit.
We recommend NOT to set values above 4.0.
10.2.3 Tilt compensation
Fig. 79 Fig. 80
Allows to enable/disable the tilt compensation function of the vehicle (with antenna only. See ARAG catalog).
(
Tilt compensation enabled / Tilt compensation disabled).
Navigator can set off any measurement errors due to ground inclination.
On steep slopes the error can reach 2 m / 6.5 ft.
