This may be a newbie question but does Flight Tracker monitor VFR aircraft positions. I am under the impression that these don't use squawk codes but are monitored by airport radar. I am in Sydney and I would like to watch helicopter movements as I am along a popular flight path.

Do you or others know how these are usually tracked?

Daniel

Thanks Daniel,

My site only tracks aircraft that transmit ADS-B which is usually commercial aircraft. Non ADS-B transmitting aircraft either need multlateration (MLAT) which I believe is where aircraft locations are calculated mathimatically by multiple people receiving ModeS signals and sharing the data (I could be wrong here). Or alternatively by standard radar.

Thanks Bob,

Yeh it's a great site. I know there are a few people that have done similar things to what I've done but I like the buzz of knowing I have developed this all by myself and learned it all as I went. This was really for my own benefit to view aircraft positions on google maps. If other people enjoy the site, then that's an added bonus.

Just a FYI.. I've just recently moved to Brisbane from Sydney and have now brought my flight tracker site up for Brisbane.

Incidently, I'm now getting much better coverage than I was in Sydney ;)

Just a reminder if your interested.. http://www.flighttracker.gleff.com
