Before attempting to diagnose a fault please ensure that you are using the correct power supply and the power cord supplied with Rosetta. 95% of faults will be corrected if this advice is followed. In addition, please ensure that your license is current. The expiry date will be shown on the home page of the PilotAware web pages. To renew your key visit https://pilotaware.lode.co.uk and choose 'renew your key'.
The following pictures show the components of the PilotAware Rosetta
(i) Front view with the end cap removed to show the GPS module in the top left-hand USB slot and the RTLSDR 'Software-Defined Radio' module in the bottom right-hand slot.
(ii) Left side view showing the connectors for the power, HDMI and 3.5mm stereo audio out connectors. The HDMI monitor interface is used by advanced users to view the software as it is loaded. There is no video or graphical output from this interface. A 1-metre power lead is supplied with the Rosetta unit but not shown.in this diagram.
Rosetta Operating Lights;
On the main Rosetta unit and the GPS module, there are LED lights that can be used to ensure that all is working well and can also be used for the diagnosis of faults.
LI This is located on the left-hand side of the Rosetta unit below the L1 sign on the label.
L2 This is located on the left-hand side of the Rosetta unit below the L2 sign on the label.
L3 This is located on the motherboard inside above and left of the power connector.
L4 This is located on the motherboard inside above and left of the power connector.
L5 This is located on the underside of the GPS module and is labelled Power
L6 This is located on the underside of the GPS module and is labelled PP
On initial power, the red light L3 on the Raspberry Pi board will light and should stay on as a solid red-light indicating power. This red light should NOT flash if it does then there is a power supply interrupt problem. This is usually caused by the micro USB connection becoming weakened through rough handling. To check whether this is the problem gently waggle the cable and the red light should stay solid. If it does not then either the cable or the socket is faulty.
On startup the sold red LED L3 is accompanied by the green LED light L4 which will flash as the system boots up. When the unit has loaded the software and booted up the normal state is for the Red L3 to be permanently on and the Green L4 to flash intermittently as SD card access is made. If L4 is permanently Green, then this usually means that the SD card is dislodged or faulty. If the SD card becomes dislodged, turn the power off before re-inserting otherwise the software may become corrupted. If the software becomes corrupted a manual software upgrade is required. How to do his is shown in the knowledge base section of the pilotaware.com website.
Lights L1 and L2 are further diagnostic lights. L2 mirrors the indicators in column 1 on the PilotAware Home Page through a series of individual flashes either green or red.
L1. This illuminates when there is a PilotAware P3i, Tx or Rx signal. Red = Tx. Green =Rx.
L2. Solid Green All OK. Alternate, Equal Length Flashing Green and Flashing Red = License Expired
L2 will also pulse 4 serial flashes in line with the indicators on column 1 rows 8 to 11 of the Rosetta Home Page.
1 status of ADSB received signals in last period
2 status of the P3i TxRx
3 status of the Barometer
4 status of the GPS
🔴🟢🟢🟢 indicates no 1090MHz (ADSB Mode-C/S). (This is temporary if nothing is received for 5 Seconds)
🟢🔴🟢🟢 indicates no PilotAware transmission usually a bridge fault or no GPS lock has yet been achieved.
🟢🟢🔴🟢 indicates barometer fault or No GPS lock achieved.
🟢🟢🟢🔴 indicates GPS Fault (weak reception) or GPS missing or dislodged.
Often a single fault will cause several red indicators. For example, loss of a GPS signal will also cause loss of P3i Tx and the barometer this will result in four flashes of 🟢🟢🟢🔴
No 1090MHz reception as well = 🔴🔴🔴🔴 check power, GPS and RTL-SDR modules are seated correctly and identified in the last 4 rows of the Home Page.
Note the serial flashes coalesce so four green flashes appear as a solid green etc.
These colours will also be shown on the home page column 1
L5, located on the underside of the GPS modules labelled Power will be permanently on (Red) when powered.
L6 When the GLONASS GPS has achieved a satellite group fix, the GPS module L6 will flash green with a period of about 1 second. If this is not flashing at a period of 1 second, then less than 4 satellites are available and therefore no fix has been achieved resulting in Rosetta not working correctly. Move the Rosetta to get a better GPS fix and the green light will commence flashing. The Rosetta GPS modules used are very reliable so if the GPS is not flashing green it is because it does not have a good view out of the aircraft or building. If you are testing at home.
The Rosetta home page will indicate how many satellites have been captured and how many are being used. This should normally be above 3 but ideally, 7 or more should be captured when outside a building or in the aircraft with a good view. You will possibly not get sufficient satellites if you are indoors but will be OK in the aircraft.
Also, on the PilotAware Web Home Page Column 1, lines 8 to 11 show the status of the individual interfaces. All greens are good with either red or amber being used to aid system fault diagnosis.
Difficulties in connecting PilotAware to Flight- Bag Applications
If you are having difficulties connecting to your Flight Bag Application or there are regular disconnections when using your PilotAware Classic or Rosetta Unit Please read the following document to help you understand and fix the problem.
There is also the following Youtube video that describes issues that you may be having https://www.youtube.com/watch?v=qwGTQdz81zw
Android devices encompass a broad range of technologies. If you are having problems with WiFi disconnects this can often be solved by ensuring that the Android power saving facility is turned OFF.
Updating PilotAware Software.
PilotAware software is revision controlled with the following naming convention. PilotAware Version (YYYYMMDD). New software is issued regularly; it is, therefore, easy to see if there is possibly a later version than the one that you are using.
To update your existing software please follow these instructions
