How to get a job offer from Foref1ight:

Develop an ads-b receiver with stuff available at amazon that costs $113.90. I think I'll build one.

Edited: Company name.

[peevee]

wonder if it'll work with wingxpro... I'd build one, why not.

[Yetti]

I have been saying this is possible for about a year.   Just did not have the time to do it.    Wonder if you can write up a spec sheet and then consider it owner supplied parts?

Dude is a badass but needs less reddit altruism and more business plan and capital to build and sell a $200 competitor product.

I have a RasPi card that I bought for a project that never materialized... tempted to make a set however being in Canada, there is no ADS-B in my area so cannot really test this.

This thread (on the link you provided) has lots of posters and a lot of interest. This shows that there are more desperate CBs (like me) than we think.

I have played around and recorded some of the 978mhz out transmissions from my transmitter with a software defined radio. The modulation scheme is Frequency shift keying and was fairly easy to write code to demodulate the IQ recorded data files and produce the stream of 1's and 0's. After finding a draft copy of the protocol I was able to parse out all the data about my flight. I'll post some pictures tomorrow when I get to work.

How soon before there are nefarious applications for doing stuff like this?  Once the protocols are decoded couldn't some dipshit spoof the system and create a bunch of false traffic?

I'm thinking that the portable ADSB in units people are buying like hotcakes will be more or less worthless soon after 2020, so I don't want to buy one.  I also think prices for ADS-B out equipment will continue to drop in the next 4 years.  

 

This Raspberry Pi device will give me the weather I want until a certified in/out device is installed a few years down the road.

ill kick in $200

.maybe more.

[Will W]

Wow, I'm shocked there is another reddit user here. I saw that yesterday though and sent that to my buddy at foreflight. No reply. I'm bored enough at work to build one.

ISIS will probably take advantage of this to cause mass destruction.

This could be one of the reasons we must retain our Mode C transponders. I believe the FAA is retaining all the approach radar infrastructure and will be able to "see" any false signals.

Creating a $200 competitor product might be the more selfless act.

Competition is good...

I'm not designing or selling anything. I'm not that talented or knowledgeable. A reddit user u/strangerwithadvice posted a step by step guide of how to build a ads-b receiver with off the shelf parts for a little more than $100. someone purported to be with fore flight invited him to take a look at their job vacancies. I linked the thread in the first post.

I did order the parts off amazon and I'll report back how it works out. I'm hoping the guy that put this together will make it easier to install and set up the software.

It uses a cheap tiny computer called a raspberry pi. I currently have one that controls my smoker and sends me a text when the ribs are done.

This won't supplant certified solutions. It might give some of us cb's some free weather on our iPads though.

Infrastructure....Something was sure messing with SoCal today. Multiple Aircraft were getting TCAS alerts and SoCal didn't see the targets on there screens. They gave me 3 transponder codes between VNY and MHV. Each time they asked me to ident. Luckily it was unrestricted visibility! I checked in and they were strangly pissed off sounding on the radio. The controller later apologized and mentioned something about a new system.

Are they using any encryption? If not it means two things:

1. It will be easy to clone (any Joe with computer / electronics background, like myself could get something up and running)

2. This opens potential for all kinds of bad things to happen if any Joe can mimic real aircraft data (use your imagination)

A while back I was curious about the data being transmitted from my ADSB out box and recorded RF output as IQ data.  After writing some software to demodulate the FM transmission I was able to parse the data that was being sent.  The top graph is the Theta component of the IQ data, the second is the demodulated waveform showing the individual bits of data and the data below that is my aircraft info.  It was only a couple of nights work.

There is no encryption, using the draft copy of DO 282B which can be found online it was very easy to parse the recoded rf once the demod part of the code was done.

It wont be long now until the Black SUV's show up. You may have already been approached by bearded men carrying briefcases full of cash for your program....

I'm using Jim as a character reference if the guys in black SUV's show up.

Why beards? I get the SUVs, but I thought distopian evil government guys in black suits had dark sunglasses and were clean shaven.

those guys would never be carrying bags of cash, the other guys would, however.

Add an IMU to the project and you could be a Stratus killer.   https://www.pololu.com/product/2468

Ah what the heck.  Add the GPS module.  Use one of the PICO Projector onto the windscreen and then you have a HUD
