Heading
GALILEO
Check this button to enable GALILEO tracking. Clear
it otherwise.
GAL
Parameter Designation $PASHS
Mode
Make the appropriate selection:
• Off: No heading measurement requested
• External: Heading measurement
requested, external GNSS receiver and
its antenna used to provide the receiver
with the appropriate data.

Input Port
(Visible only if Mode= “External”) Choose
the serial port through which data from the
external GNSS receiver (and the second
GNSS antenna) are applied to the receiver
(A, B, F, C, D, E, I or P).
CPD,ARR,MOD
Baseline Length
Enter the distance between the two anten-
nas used (baseline length).
Setting this parameter to “0” forces the
receiver to start an-auto calibration
sequence.
Auto Calibration: Checking this button
amounts to entering “0” in the Baseline
Length field, which, as explained above,
will result in starting an auto-calibration
sequence.

Azimuth Offset
Designates the angle deviation (0-359.99°)
between the horizontal component of the
baseline and the horizontal direction of the
object for which you want to determine the
heading.
This parameter makes sense in a vehicle
for example where the baseline resulting
from the installation of the two antennas is
not parallel to the direction in which the
vehicle is moving (default: 0).
Specifying the azimuth offset also allows
the receiver to deliver an accurate mea-
surement of the roll or pitch angle (depend-
ing on whether the baseline is oriented in a
direction respectively perpendicular or par-
allel to that of the vehicle).
Keep this parameter equal to zero if it does
not make sense to define an azimuth offset
in your application.
