That's tue, but I checked before buying the Ryan and the Chelton and Garmin will both accept RS232 input from the Ryan.

Active certainly gives you more control, but passive coverage looks pretty good. One way to make both systems much more effective is to imbed the aircraft target gps coordinates in the transponder signal, for those aircraft that have gps. Very simple approach. Would provide much more accurate aircraft tracking not only for aircraft avoidance but also for FAA tracking, even more accurate than sophisticated military tracking radars can provide.

>Note that the Zaon is a passive system, relying on ground radar or on
other TCAS-equipped aircraft to generate the "pings" that will bounce
off target aircraft. So if you're too far from a ground radar, and
there's not an airliner with TCAS nearby, you might not see another
aircraft because no one is interrogating his transponder.
Ryan TAS, on the other hand, is an active system that generates its own
"pings" so it will detect anyone with a transponder, regardless of where
you are.

You’re too late – you’ve just defined part of what ADS-B is . . .

Great, simple effective technology, don't need to make it harder than it is. I don't see why the site seems to keep emphasizing not intended as a collision avoidance system, except for the obvious fact that not all aircraft will have the extended transponder mode available initially. All the key ingredients are there and a lot more accurate geo-coordinate positioning potential than what you can get out of Radar directly. I suspect as they gain confidence with the system that will change.

ADS-B
If ADS-B is going to replace the transponder interrogation and reply processing in today's working (albeit line of sight) system, what's to keep the ADS-B data from being preprogrammed to send out false information?
Transponders provide altitude and proximity data based on tower interrogation and signal response and strength?. ADS-B apparently supplies digital data on 3D location, etc. Well anything digital can be recorded and played back. i.e. spoofed unless digital signature and private key infrastructure are employed to guarantee the sender is who they say they are, and the packet has not been tampered with and is coded with the current session key. This is being done today on the internet for securing transactions requiring session keys, pki certificates, etc. associated with secure transmission over the internet.
What does the current ADS-B do to guard against spoofing the ADS-B system?
After 911 we don't want to give away a system which is old for one that can be spoofed...
Remember how Glacier Gale got left on the glacier in the first place...

Because it only show active participating aircraft with transponders on.
Radar shows more if it is line of sight. No system is pefect.
