11.1.3 Line 3
The third line of the oled display shows the state of the IMU/GNSS sensor. The possible states
of the GNSS sensor are
-
ERR No signal
-
This indicates the on board Imu/GNSS is not connected. Contact your
distributor if this occurs.
-
ERR No Nav
-
This indicates that the GNSS is not getting any signal from it’s antennas. This is
most likely caused by a faulty antenna connection. Recheck the connections at
the top of the RN50 system.
-
ERR Init Heading
-
This occurs when the antennas are properly attached to the system before it
has a GNSS fix. This will take up to 2 minutes. If this continues to occur, firstly
ensure the payload has a very clear sky view and both antennas are not
obstructed in any way. Secondly, make sure that there are no signal reflections
that could be occurring due to surfaces next to the system. If problems persist,
check connections to antennas at the top of the RN50 unit.
-
Warn Acc Over Range
-
This occurs when the onboard IMU is subjected to more the 2g of acceleration.
This can cause an error in data quality if the system is continually exposed to
high accelerations during data capture. This will not occur during a flight if the
mission planning guide and vibration isolators are used. This may however
occur on take off or landing of the system due to the increased acceleration of
the system. If this occurs on take off or landing the quality of the data will not be
affected.
-
OK “GNSS” Fix
-
This indicates that the system has a lock on a GNSS position and the system is
ready for data capture. Depending on location and time the system will lock on
to various constellations including GPS, GLONASS, SBAS. The sensor may also
present a 3D fix when using multiple constellation systems.
11.1.4 Line 4
The fourth line of the OLED display shows the internal state of the on board computer as well
as the API designated flight controller. The possible states are:
-
STR ##.#GB free
-
This indicates the amount of free storage space inside the payload - note this is
different to the USB thumb drive.
