What is Transmitter?
What is Transmitter?
It is a small Windows application that transmits your position in Microsoft Flight Simulator to an online database where your last reported position is held for 1 minute. The website then produces a "whazzup" formatted file that can be used by LittleNavMap to plot aircraft positions live on a map.
Why do we need Transmitter?
Why do we need Transmitter?
If you and your friends want to see each other on mapping software such as LittleNavMap to run your own air traffic control sessions for group flights, you will no doubt have discovered that Microsoft Flight Simulator only communicates AI aircraft to external mapping applications such as LittleNavMap - not users. The Virtual Flight Online Transmitter application addresses that.
How does Transmitter work?
How does Transmitter work?
The desktop application connects to a running copy of Microsoft Flight Simulator via the SimConnect interface, and reads your aircraft's latitude, longitude, altitude, speed and type. It combines the data with your keyed callsign and name, and sends it to a server on the internet via the "Server URL" entered into the application.
The server then provides a URL that outputs all aircraft that have been updated in the last few seconds in "whazzup" format - a data format commonly used with the likes of VATSIM and IVAO - and crucially LittleNavMap. The URL of the server can be used to configure LittleNavMap to show you and your friends aircraft on the map.
Configuring and Running Transmitter
Configuring and Running Transmitter
Download and install VirtualFlight.Online Transmitter
Launch Microsoft Flight Simulator.
Run "VirtualFlight.Online Transmitter".
Fill out the text boxes for:
The server URL - http://transmitter.myair-virtual.co.uk/send
The server pin - ask the group during a group flight
Your callsign e.g. G-ABCD
Your name e.g. Fred Smith
Your group name e.g. MyAir Virtual
Click Connect
After clicking connect, the application will broadcast your location within the simulator to the internet once a second.
Important note - the pin number you fill into the Transmitter client MUST match the pin number of the server - if it doesn't, your transmissions to the server will be ignored.

As can be seen in the screenshot, once Transmitter is configured and connected, the text-boxes grey out, and a timer starts at the bottom of the screen.
Configuring LittleNavMap to show aircraft broadcasting via Transmitter
Configuring LittleNavMap to show aircraft broadcasting via Transmitter
To show other aircraft using Transmitter in LittleNavMap, you need to configure LittleNavMap to receive custom "online flying" data.
Within LittleNavMap:
Click on the Tools menu
Click on Options
Select the Online Flying section within the Options panel
Choose the radio button for "Custom" within the Online Flying section
Fill the URL field - http://transmitter.myair-virtual.co.uk/whazzup_ivao
Set the update rate to 5 seconds
Make sure IVAO is chosen in the format drop-down
Click Apply, and OK
Once configured, the red aircraft icon in the toolbar in LittleNavMap will show and hide the "online" aircraft.
If you cannot make it work, make sure you do not have any spaces on either end of the URL in the custom URL field.
