The web interface
shows
No position fix.
The EXPLORER 540 is unable
to register on the network,
because the GNSS position is
unknown.
Make sure the view to the GNSS
satellites is not blocked.
To obtain position fix, the
EXPLORER 540 should be placed
flat on an even surface pointing
straight upwards, with a clear view
to as much of the sky as possible.
When the EXPLORER 540 has
obtained position fix, you can
point the antenna towards the
BGAN satellite.
You can see position status in the
Dashboard of the web interface
(status section).
The web interface
shows
Not registered.
The EXPLORER 540 cannot
register on the BGAN
network.
Check that your SIM card is valid
for communication on the BGAN
network.
Check your subscription with the
Airtime Provider.
The web interface
shows
External control.
The EXPLORER 540 is
currently controlled by an
external application, e.g.
LaunchPad or an AT
command interface.
If you want to use the built-in web
interface, stop the external
application and restart the
EXPLORER 540. Then open your
browser and access the web
interface.
The EXPLORER 540
cannot obtain its
position using GNSS.
There is no GNSS signal, or
the signal is weak.
If the EXPLORER 540 has not
been used recently within the
same location, it can take up
to 10 minutes to obtain the
position.
Check the position status in the
web interface.
To help the EXPLORER 540 obtain
position fix, it should be placed
flat on an even surface pointing
straight upwards, with a clear view
to as much of the sky as possible.
When the EXPLORER 540 has
obtained position fix, you can
point the antenna towards the
BGAN satellite.
