Please don't leave, Sarah. You've at least had something intelligent to
say on the original topic of this post.

Ok, I'm out. Civil conversation has ended here.

Oh, big misinterpretation here. I joking as I responded to and with quoted text of another's post regarding Sarah Palin, especially in light of her recent endorsement "speech" of the Donald. I certainly would not insult anyone on this newsgroup. And to have a lady actually post and comment is great as we have virtually no ladies flying or posting.

Okay. I've been in contact with some folks developing ADS-B In receivers and the associated software. Providing NMEA serial output for ADS-B traffic (specifically PFLAA and GPRMC sentences) is now on the development list for Stratux - which is the open-source software project for ADS-B In. It will allow you to connect your glider flight computer to any of the inexpensive single or dual-band ADS-B receivers based on Raspberry Pi.

I have also take with one of the commercial hardware developers for ADS-B In receivers - FlightBox. They will have a product out this spring for $150-250 for UAT only and UAT/1090ES respectively. You should also be able to pick up TIS-B - either what's intended for other aircraft near you, or tailored for you if you have ADS-B Out. I have not yet figured out exactly how to configure ADS-B Out to get the correct TIS-B traffic - but that should be just setting parameters. Since I don't have a way to do ADS-B Out yet that is a future project.

It requires a little work to add a serial port to the hardware so I'm trying to figure out how to get that done too. If there were enough interest I suspect it could get manufactured professionally rather than being a home electronics project.

If you want to use it standalone it should work as-is, but you could also use it with Flarm or PowerFlarm and use a K6Mux to combine the NMEA traffic streams and connect to a glide computer serial port.

I'd be interested in whether people have an interest in such a device - I suspect Dan does. Any others?

Sounds fun, and we are currently working on some parallel ideas with a small start up. I would be happy to join in on your project.

Yes, I'm interested though my needs have recently changed.

I'm offering for sale my LAK-17a just as soon as I can write up an ad
and post some pictures. Later I'll be selling my Pipistrel Sinus.
These two have to go to make room for the Stemme S10-VT that will soon
be coming. :-D

Some news on TIS-B services.

It appears that the FAA will be modifying TIS-B to make it available to anyone with an ADS-B receiver, regardless of ADS-B Out carriage. This means that you should be able to see rebroadcast of all transponder-equipped (as well as "opposite-band" ADS-B Out) aircraft within range of SSR with resolution as good as a few hundred feet simply by acquiring one of the relatively inexpensive ($100-150) ADS-B receivers. It may be available as early as this summer. It appears that this will enable a "God's eye view" of all transponder-equipped gliders (and other aircraft) in a broad flying area so long as there is SSR coverage. It remains to be confirmed whether or not PowerFLARM ADS-B In can decode TIS-B traffic. My understanding is that nothing special was included in the PowerFLARM design to accommodate TIS-B, but I am unsure whether TIS-B traffic resembles ADS-B direct transmissions closely enough to be decoded by PowerFLARM anyway. Either way there ought to be a glider-relevant solution available this year.

Additionally, it seems that the FAA will now rebroadcast ALL traffic regardless of ADS-B Out performance and configuration. Previously, some aircraft would not be rebroadcast if their ADS-B Out did not meet certain performance criteria and, as a result, would effectively be invisible so far as TIS-B services were concerned.

Things are moving pretty quickly. Surprising.

I want to ask Flarm Inc. for clarification on this point, but I'm not sure of how to ask the right question.

I believe that you are totally misinterpreting the information in the AOPA link you provided. While AOPA has been lobbying for years for the FAA to transmit all TIS-B data so that aircraft without ADS-B OUT will have access to this data, this is NOT what the FAA is doing. Instead, the FAA is actually clamping down and will no longer transmit TIS-B data to aircraft that are equipped with ADS-B OUT equipment that use GPS position sources that do not meet minimal performance standards.

If you want to reliably receive TIS-B data from an ADS-B ground station, your aircraft MUST be ADS-B OUT equipped.

Note: PowerFLARM does not support TIS-B and there has been no information provided by anyone that they are even thinking about adding this functionality to their product. That's a huge shortcoming in the product that is certainly not helping their sales efforts.

I read the AOPA article the same way Andy does.
The ghosting thing is a problem, alarms that "you're near yourself" are useless.
But that's always been a problem with non-FLARM proximity warnings, the algorithms are not set for simple things like sharing a thermal.
