Passur was a precise MLAT network supplemented with the FAA feed to identify the planes. The display features weren't so great, but the basic scheme
worked very well. There was no way to get a trail from passur, so I had a macro to stack images. Sometimes I set up my PC to record the display window
as an AVI, then stacked those frames.
The webtrack sites are hit or miss. There doesn't seem to be a consistency on how they are filtered by the FAA, or perhaps how webtrack filters the
feed. In socal and norcal, there is much overlap between airport surveillance, so you can check a few feeds to find the plane. If you got a mode-s hit
(but not ADSB), you try to find it in the likely airspace on the tracker site. Once in a while webtrack locations are just totally wrong, like they
latched onto the wrong plane.
If you have a mode-s box and contribute, you can get much of the data off of
It has the regular mode-s and ADSB. At the moment, there is a reliable Vegas box on the network.
Plane Plotter can in theory track planes without mode-s using MLAT, but the program is really crap. When the program isn't crashed or just plain out
to lunch (appears to be alive but not feeding data), the MLAT is good to maybe 3 miles at best. More like 5 miles. Save your money. I've never been a
fan of one-person software companies. This COAA is the worst I ever encountered.
The next generation Beast will have real MLAT built in using GPS timing and won't need junk like planeplotter to mlat.
The designer is German, so the English is a bit choppy. But the engineering is good.
