Probably not FAA certified for transmitting ADSB info... just a guess there.

not FCC certified to transmit ANYTHING on ANY FREQUENCY, not FCC certified for not causing interference with other equipment, use at your own risk, etc. if you order one of these from a foreign website, don't be surprised if it gets confiscated by customs.

Good luck.

While I think this is a design for a transceiver, building ADS-B receivers has become popular lately because of Flightaware.com's crowdsourcing of ADS-B reception. The more homebrew people out there that are feeding their network and data, the better.

Instructions for building one from a Raspberry Pi.



Also, "you're" is a contraction of "you are." Thread title makes no sense. /punctuation_special_forces

An SDR setup that actually works is not that hard to build for about a third of the price. This may make a nice dev kit to develop a UAT or 1090ES unit.

I just ordered this. Thanks.

For those with concerns about the legality of the device, consider the regs (http://transition.fcc.gov/Bureaus/Engineering_Technology/Documents/bulletins/oet63/oet63rev.pdf), review the spec sheet, and know that it should be trivially easy to stay legal with this device.

Cool idea. I have a beaglebone black that might make a good project for this.

I wish foreflight had a more open integration model with hardware other than appareo. Then again I wish Apple did too.

Yes, I know. Typed that while on a conference call...

HA! Fixed it.

So, what are you guys using these things for? I'm very interested in find out more about them. I've seen the Flighaware project before, and should read the regs on their uses. What are you using them for?

The BB is nice, but the 1080p HDMI or even just s-video on the rPi would allow direct video to a number of 50-60 dollar, 500-800 NIT displays (daylight readable). Add silicon for BLE and tether off your cell phone, and you have a total EFB solution. Going even further with some adc channels, and a complete flight and engine monitor could be added (thermocouple inputs, tachs for engine and fuel flow, etc). And AP outputs, if desired. Touch screen. Add planning software, and why would a guy need a $5000 portable any longer?

This thread is jibberish and jargon for geeks. [emoji6] (I wish I understood)

I guess I'll have to buy my ADSB receiver.

x2. Except I don't really wish I understood.
ADS-B in -- who cares? Isn't ADS-B out what is being mandated for 2020?
Sorry about my negativity, but I'm not looking forward to ADS-B and will have to be dragged kicking & screaming into it.

From reading through the ReadMe file in one of the links, it looks like one of the primary uses other than Flightaware is for flight simmers to be able to generate real-time traffic while they are flying in their game. Interesting stuff.

With the transmitting ability of the HackRF, the thing I would worry about is the ability to do the reverse - some pimply-faced 13 year old kid that figures out how to generate ghost ADS-B traffic that disrupts the system in already critically saturated airspace. Again, interesting stuff...that keeps me up at night!

Their, they're, there, Zane. It'll be all right...

"They" already have. It has been demonstrated publicly several times, and privately who knows. The FAA stays up nights trying to solve the problem by measuring time of flight and getting rid of spoof and artifact signals. Allegedly, this cleans up the ground based system that is broadcast. The air to air component has no such filtering, and can be spoofed. I imagine this is part of the reason the FAA decided it cannot get rid of primary radar after all, making most of the NextGen system upgrade motivation superfluous.

It is superfluous anyway...no way the FAA is going to drop primary radar for a system that will not allow them to see an unequipped target in class B or C airspace.

Back in the dark ages I used to assemble Heathkit ham radio equipment, as well as stuff made by a company called EICO.

Anyway, maybe this is an opportunity for some clever business man ( I can't figure out how to spell entrepreneur ) to come up with a cheap effective home brew ADSB kit. The Dual 150A can now be had for $89 dollars on line, so a kit would really have to offer some super features and/or great value. Good deals on ADSB......them's thayr sumwhayr....
