6. Quick Configuration 🚀

Rosetta & Classic Instructions




Before taking Rosetta in the air, the device first needs to be configured.

Here, we will cover the basics just to get you started. For a more advanced configuration please visit the appropriate knowledge base links.

Step 1;

Connect a mobile device to the Rosetta Wi-Fi hotspot. Then open a web browser (Safari, Chrome, Firefox) and type '' or 'paw.local' into the URL address bar and submit.

Step 2;

The PilotAware Web interface will then appear. If you get an error, please check the Wi-Fi connection, and ensure that the URL entered is correct.

Step 3;

Select ‘Configure’.

⚠️ Information; ⚠️

It's recommended that the following initial settings are adjusted to suit your aircraft.


All aircraft registered anywhere in the world will have a unique ICAO number. If you don’t know the ICAO (Hex-ID) of your UK registered aircraft, it can be found by searching your aircraft registration in the G-INFO  database on the CAA website. Please check with your local aviation authority. FlightRadar24 is a good resource for Hex-ID identification.

Insert your unique ICAO code in the Hex-ID field. This will make sure Rosetta ignores any EC messages from your aircraft. If this is not done you may be continuously reporting an aircraft on top of you which will be you.

The HEX-ID must be correct.

An example of a Hex-ID is; 405B19

Ensure you insert this correctly and dont confuse the digits. In this example 0 is ‘Zero' not O ‘Osca’ and B is ‘Bravo’ not 8


Add your Flight ID (8 characters maximum). Usually your registration I.e. G-ABCD but it can also be anything else such as VINTAGE1, FALCON9 or TARDIS. This is received by PilotAware and ATOM stations.


The Group-ID allows for the easy identification of aircraft within a group fitted with PilotAware. This can be left as PAWGRP.

For example;

The Eurostar group chooses a Group-ID of 'EV97', which is entered into the Group-ID of each PilotAware unit. Now the Flight-ID of each Eurostar member will have the registration of the aircraft prefixed and suffixed with a hash. #G-EURO#:

Aircraft Type;

Transmit the aircraft category from PilotAware to alert local pilots and ground stations as to your aircraft type.

For example a Cessna 152 should be declared as Powered.

Mode-C/S detection and settings;

Rosetta is capable of detecting Mode C and S transmissions as bearing-less targets. A bearing-less target does not transmit a GPS co-ordinate and therefore cannot be positioned on a screen. However, a relative height and distance based on user defined signal strength can be useful. The Mode C/S box is set to disable by default. Please read and understand the description of how this works before enabling this facility. 

We recommend setting 'Mode-C/S Select' to 'Mode-C/S + Filter' as this includes additional filters to remove any Mode-C element transmitted from your aircraft.

For the horizontal sensitivity, we recommend 'medium' to start with. This can be revised to suit your experience and flying style.

For the vertical filter, we recommend '2000ft' to start with. This value can be changed later to suit your preference.

Enabling Mode-S/3D;

Mode-S/3D is our latest innovation. The MLAT (Multilateration)  derived location of Mode-S aircraft is uplinked to PilotAware via our ATOM stations. This is then used to provide the position of Mode-S traffic on a navigation display such as SkyDemon. This is a unique feature of PilotAware and its operation and limitations must be fully understood before its use is enabled. A full description is available in the following document.
