A friend flying on the west side of the range got a visit from an A-10 rocking its wings. He was still in free territory, but the A-10 had a different
There is a lot of VFR traffic on the east side of the range that never gets logged on the internet. The planes are not required to have ADS-B yet in
the US. [Loosely called Nextgen.] In Europe, they must have ADS-B, so flightradar24 tracks a lot more aircraft there. I've visually spotted the DOE
Beechcraft flying along the east side of the range, but east of the ET Highway as well. I don't know if there is a visual flight corridor there, but
I suspect the aircraft use the ET Highway to insure they don't drift into the Nellis range. On the west side of the range, there is considerable free
territory on the east side of route 95, so the planes don't have a good visual guide. Flying west of route 95 involves not running into mountains.
There are three basic ways civilian aircraft are identified. There is the traditional transponder where the pilot enters a code assigned by air
traffic control (ATC) over the radio. Without the assigned code, the plane is just a blip on the screen with no accurate data regarding altitude. The
transponder reports either the altitude or the squawk code depending on how ATC interrogates it (based on the signal ATC transmits). Mode-s is a
variant on the old transponder scheme except that each plane has a unique (in theory) code assigned to it. This is generally referred to as the hex
code or ICAO code. These codes are documented by the FAA in the US or the controlling authority elsewhere.The plane still has to be pinged by ATC to
make it talk. ADS-B is a bit different in that it just chirps all by itself. I'm not entirely sure how they deal with multiple signal being received
at the same time, other than the code has some error checking bits. The receiver software tosses out any data that doesn't pass parity checks in the
case of mode-s or error checking in the case of ADS-B. This isn't a big deal since the plane can be interrogated again or the ADS-B will give out
Military aircraft do not have their codes documented, well at least in a public document. At the moment, only the heavies have the gear (tankers,
cargo, E-6 Mercury, and U-2). For civilian use, the codes need to be determined visually (watching the plane on the receiver and noting the tail
number as it lands), by callsign in some cases (Reach flights), and HFDL decoding. That is where this website comes in handy.
Live military mode-s tracking
It is essentially a crowd source document of military hex codes as well as tracking with coarse geographical data.
To get all the data on the website, you need to feed the system. This should be doable with Virtual Radar Server, which can take the AVR format data
from DVB-T dongle and convert it to Kinetics SBS format.
I predict in short order Airnav and Kinetics will make a dongle for such detection. Not for $10, but a dongle in the $100 range with a bit of front
end filtering and turn-key software. The hand writing is on the wall. If they don't do it, someone else will.
