Traffic targets between ADS-B and Mode S

[skydancer]

Can any of you share the wisdom with me...

I am already getting traffic targets from SV-261 mode-S transponder, if I add an ADS-B to the system, which target would be shown on my skyview?

The ADSB will show all traffic that ATC see's plus the weather. A very worthwhile investment. You will not regret installing it in your aircraft.

So the TIS from the 261 only gets you traffic in TIS coverage zones near major airports, while adding the ADS-B box gets you traffic everywhere that there's an ADS-B ground station installed. And because you have the ADS-B Out and In sides in SkyView, you'll get all the traffic that the FAA knows about, inluding Mode C targets that are under surveilance.

What exactly does Mode C targets that are under surveilance mean in relation to displaying the traffic? Also I had a drone pass by approxiamately below and it never showed up on any of my traffic systems.

To clarify - you get Mode C targets when they're being painted by radar, and an FAA radar station somewhere (center, enroute, approach, etc) is picking the aircraft up. Then it gets beamed to you via ADS-B. Basically, when you have ADS-B in and out, you see what the FAA sees.

Is there a way of identifying which system (ADSB Module vs SV-261) received a particular target?

 

[Dynon]

Traffic data from different sources isn't fused. So if it says ADS-B in the lower-right hand corner, that's where it's from. Else, it's TIS from the transponder.

THANKS!

I flew with Dynon TIS for a year then installed the ADS-B when it shipped.

Yep, its a grand but it will be the best grand you ever spent. The increase in awareness is not to be believed. This assumes you are in a place with airports and traffic. If you are in the middle of nowhere with zero radar coverage then traffic is probably not very important for you.
