$JATT,NEGTILT,YES<CR><LF>
To return the sign of the pitch / roll measurement to its original value, issue the following
command.
$JATT,NEGTILT,NO<CR><LF>
To query the Vector Sensor for the current state of this feature, issue the following command.
$JATT,NEGTILT<CR><LF>

Pitch / Roll Compensation
You may adjust the pitch / roll output from the Vector Sensor in order to calibrate the
measurement if the Antenna Array is not installed in a horizontal plane. The following NMEA
message allows to you to calibrate the pitch / roll reading from the Vector Sensor.
$JATT,PBIAS,x<CR><LF>
Where x is a bias that will be added to the Vector Sensor’s pitch / roll measure, in degrees. The
acceptable range for the heading bias is -15.0
°
to 15.0
°
. The default value of this feature is 0.0
°
.
To determine what the current pitch compensation angle is, send the following message to the
Vector Sensor.
$JATT,PBIAS<CR><LF>
Note - The pitch / roll bias is added after the negation of the pitch / roll measurement
(if so invoked with the $JATT,NEGTILT command).
