sorry if this is a thread drift....but.
do you guys realise that there are more people outside of aviation playing with ADSB than there ever will be inside of aviation.
my boy has hacked his way through most of his experiments, but hasn't quite got the final thing working. there are evidently thousands of people playing with this.
using an american data mobile phone connected to a raspberry pi and a bunch of code in the raspberry pi to decode the adsb signals he has full output of everything the adsb system is transmitting line of sight.
he is working to input the information to his oz runways display on his iPad.
very interesting.
once the prototyping is sorted the chipsets get made into a reliable board and become a commercial product is my guess. maybe not by him but by lots of others.
