Install an Inertial+
Use secure mounting solution e.g.
RT-Strut, to secure Inertial+ rigidly
to vehicle.
Connect internal GNSS antennas
(for time/heading) then connect
the power connector.
Connect external GNSS to the
Inertial+ using a serial connection
on the ‘External GNSS’ port.
Apply power (10-28 V d.c). 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 Inertial+ model.
2. Read Confi gurations: Use default settings.
3. GNSS Selection: Choose your external GNSS receiver from the list.
4. Orientation: Set the Y and Z axis points to match your installation.
5. Primary Antenna: Measure from the Inertial+ measurement points
to the primary antenna along the three vehicle axes and enter the
measurements accurately.
6. 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.
7. Wheel Confi guration: Confi gure for land vehicles only.
8. Options: Use default settings.
9. Commit: Make sure Inertial+ is connected and turned on. Select the
appropriate IP address and click commit.
10. Save/Finish: The data will be stored internally on the Inertial+ 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.
Install software from the CD
provided. If you have trouble
downloading, please contact our
support team for more information.
