Ads-b and sailplanes

Regarding Mike Schumann's comment predicting UAVs will be equipped with UAT, at least one company offering new equipment aimed at UAVs doesn't agree. Check out the new offerings from Sagetech he http://www.sagetechcorp.com/unmanned.../#.VSZ9SPDNrkc

As you can see, they offer Mode S, Mode S with ADS-B Out and Mode S with ADS-B Out and GPS, but there is no mention of UAT. Mike, you may want to call them and explain what a huge mistake they're making.

What's with the insulting hysteria in your posts?

I am not recommending that anyone buy UAT based ADS-B OUT transmitters. The way the market is headed, the smartest choice for glider pilots may very well be going the 1090ES route.

What I am pointing out is that UAT is part of the system. There will be aircraft and UAVs out there that are UAT ADS-B OUT equipped and may not have conventional transponders. How many is anyone's guess at this time. Neither you nor I have any significant influence on what other pilots buy. This will be determined by market forces and the individual preferences of the various A/C owners.

The only thing that I am saying is that, if you are buying any avionics that includes ADS-B IN, make sure it supports both UAT and 1090ES. This can be accomplished by having a dual frequency receiver, or by correctly handling TIS-B and ADS-B R transmissions received from ADS-B ground stations.

If you are thinking about buying POWERFLARM, you need to move forward with your eyes wide open and understand that as currently implemented, you will not be seeing UAT ADS-B OUT equipped aircraft. You will also not be getting weather and notam data that is a standard feature of competitive low cost ADS-B IN products. If you want to spend money on a half baked solution like this, that's totally your call.
