If you own your own airplane, there are already panel mounted/transponder solutions. I'm not sure which, if any, are 2020 compliant. For me, as a renter pilot, the SkyGuardTWX transceiver for $1495 is an excellent solution. There are a lot of flying hours between now and 2020, hopefully, and this thing has already prevented a near mid-air collision. I had a plane closing in on me from above and behind and he never saw me. I saw him on my Nexus 7 and told him where I was.

I also don't know how they could have implemented ADS-B any simpler. You need a transmitter and receiver. How else could you do it? And actually, you only need the transmitter to be 2020 compliant.

They already have ADS-B out transponders. I don't know how many. ADS-B in is not required. I think the 1090 frequency was already getting overcrowded, so they needed to separate it. Most of us rarely fly above 18,000 feet, so it's not that big a deal. Around major airports, we'll see the 1090 traffic along with all other mode C traffic from the ground station signal. It's a non-issue.

You asked for an explanation of the difference between the Dual XGPS170 and SkyGuardTWX transceiver. I tried to explain that to you and now all you want to do is complain about how complex or expensive or too much hardware ADS-B requires. Why don't you forget it until 2020.
