Adding ADS-B /Mode-S Data

In addition to providing streaming voice, i’ll be adding ADS-B (Automatic Dependent Surveillance Broadcast ) data shortly. This will provide real-time data of aircraft within 200nm ¬†of Tallahassee (KTLH). You will be able to see the aircraft on a map and it will include data such as:

  • Lat/Long
  • Flight Number, Aircraft Type (737 etc.), Squawk and Aircraft Registation
  • Origin & Destination
  • Time in Flight and ETA to Destination
  • Altitude, Speed, Track (in degrees) and assent/descent rate (Vertical Speed)

Most services on the web (such as FlightAware.Com) show FAA filtered data, delayed by 5 minutes or more. The data feed provided by KTLH.NET and others post real-time data provided by receivers that capture the data in real time that is transmitted by the aircraft (and also captured by the FAA ground stations) and routed to services that provide real-time map display such as www.fightradar24.com (FR24).

I’m currently feeding FR24 data as T-KTLH3 (there is a 1 & 2 already) from a test location. In the works is the location of the receiver downtown at a height of 250ft which should provide reception of 300nm and greater. Currently I’m receiving about 200nm to the north.

Welcome to the KTLH Monitoring Station

Greetings:

Welcome to the KTLH monitoring station. This site will update my listeners on what is happening at the K4TLH monitoring station.

What is a monitoring station? I provide a live audio feed of the KTLH Tallahassee Regional Airport frequencies to LiveATC.Net. You can click on the Monitoring Station link in the menu to see what the station setup is comprised of. LiveATC.NET is a free site that allows you to tune into airport traffic from all over the world from your web browser. There is also a low cost app available for the Android platform as well as the Ipad/Iphone platform.

You can click here to visit the KTLH page to listen to local audio.

LiveATC does have listener forums, including one for feed operators to post maintenance issues. I think most listeners probably don’t go to the forums and I believe that this site will keep local folks better informed as to what is happening with the monitoring station.

I’ll be posting anything that happens to the station including computer maintenance, scheduled downtimes, unscheduled downtimes etc. There is alot that is going on behind the scene (especially my flaky computer) and I hope to keep everyone informed on a timely basis.
