OXTS xNAV User manual
Installing an xNAV
Use 90° brackets or alternative
mounting solution e.g. RT-Strut, to
secure xNAV rigidly to vehicle.
Align red marks on user cable
and socket, then push to connect.
Apply power (10-31 V d.c).
Connect Ethernet to the J3
Ethernet port cross coupler.
Green power LED light will
appear.
Positioning the antennas
STEP 2
Antenna separation should be
between 1 m and 5 m apart. Place
the GNSS antennas on a metal
parallel surface. Make sure the
antennas have a ground plane to
prevent GPS signal refl ection.
Follow steps in NAVconfi g:
1. Product Selection: Select relevant xNAV model.
2. Read Confi gurations: Use default settings.
3. Orientation: Set the Y and Z axis points to match your
installation.
4. Primary Antenna: Measure from the xNAV’s measurement
points to the primary antenna along the three vehicle axes and
enter the measurements accurately.
5. Secondary Antenna: Select ‘Enable Secondary Antenna’ and
enter the accurate measurements between the antennas. Measure
as accurately as possible but below 5 cm. Static Initialisation can
be enabled at this stage.
6. Wheel Confi guration: Confi gure for land vehicles only.
7. Options: Use default settings.
8. Commit: Make sure xNAV is connected and turned on. Select
the appropriate IP address and click commit.
9. Save/Finish: The data will be stored internally on the xNAV
once committed but use the option to store locally if necessary.
STEP 3
Once installed go to;
Start > All Programs > OxTS >
NAVconfi g
Allow permission for NAVconfi g to
use network. This can be changed
in windows Firewall.
Download and install software
from link or CD provided. If you
have trouble downloading, please
contact our support team for more
information.
Confi guring an xNAV
STEP 1
Ensure the orientation of the two
antennas is the same.
1 m - 5 m
LED States
PWR Green when power applied to system.
Orange when traffi c present on Ethernet.
STATUS Flashing red while searching for GNSS lock. Solid
red when ready for initialisation.
Orange after initialisation, outputs not yet real-
time.
Green when INS running and outputting in real-
time.
GNSS Flashing red while searching for heading
lock.
Solid red/orange/green for differential/ fl oating/
integer heading lock.
ON
Initialisation and warming up
In aircraft where static initialisation
is used, allow aerial vehicle to
remain stationary until system
initialises.
AUTO
RD
STEP 5
Open Windows Explorer.
RD fi les can be accessed via
FTP either using an FTP client
or the Windows Explorer fi le
management tool.
While the xNAV is operating, it
saves all data internally to a fi le
with suffi x .RD.
Static initialisation will take
approximately 30 sec-10 mins
depending on antenna separation
and measurement accuracy. The
time can be reduced by optimising
the confi guration for dual antenna
setup.
Downloading and viewing data
30 sec-10 min
Aerial vehicles should be fl own in fi gures of eight with some
acceleration and braking and with the addition of climbs and dives. After
3-5 mins system will be ready for use.
Once warmed up, system should
be left on. Turning it off will
require the warm up process to be
repeated.
The fi les on the xNAV will then
be listed and the RD fi les can be
copied to your PC for processing.
In the address bar, type
“195.0.0.nn” where nn are the last
two digits of the serial number.
STEP 4
LEAVE ON
Complete.
Support:
For further information,
please check the xNAV
manual.
If you encounter any
issues during installation,
please contact our OxTS
support team via the
website.
Note:
The system can
also be initialised by
speed.
To do so, drive above
the initialisation speed
(set in NAVconfi g) in a
straight line.
