Once installed and running, you will need to set the server URL within the Transmitter client application. VirtualFlight.Online no longer operates their own Transmitter server, but you are welcome to set your own up using the contents of the server folder (see "Running your own server" below).
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.
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.
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.
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.
The /server subdirectory contains the resources required to make your own server. You'll need some MySQL and PHP webserver experience - a database.sql file is included to create the appropriate database to track aircraft positions (used by send.php and whazzup_ivao.php). The code should be self explanatory. Remember your users will also need to change their server URL to reflect the location of "send.php" for your server.
Your webserver will need PHP and MySQL installed and configured.
The installation procedure is typically as follows:
That's it!
The two URLs you will need after setting up the server are:
If you would like to see everybody broadcasting their position with Virtual Flight Online Transmitter, follow these steps in LittleNavMap:
I don't really have time to look after Transmitter any more. It was always a stop-gap until Microsoft released a multiplayer location API - but they never have. I will answer questions about Transmitter, but please don't expect me to support your installations or modifications to the code.
