Serial Ports
This page is used to set the receiver serial ports (A, B and F).
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.
CPD,ARR,LEN
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.
CPD,ARR,OFS
Maximum Base-
line Elevation Set the maximum value of expected base-
line elevation (0-90°; Default: 15°).
CPD,ARR,PAR
Elevation Offset
Designates the angle deviation (±90°)
between the orientation of the baseline and
the orientation of the object for which you
want to determine the roll or pitch angle.
This parameter makes sense in a ship for
example where the baseline resulting from
the installation of the two antennas is not
parallel to the orientation of the deck
(default: 0).
Keep this parameter equal to zero if it does
not make sense to define an elevation off-
set in your application.
CPD,ARR,OFS
Maximum Base-
line Length Error
Set the maximum error that is tolerated in
the determination of the baseline length
(0.001-10.000 meters)
