If I’d have been using PAW, I could have avoided him by a bigger margin. (If there was a ground station nearby).
I think the real difference is that one is free and one you pay for the license.
(Though there is a PAW license to pay remember, so you just pay money to different people really)
Flarm haven’t changed their encryption key lately, though I understand it was broken quite quickly last time.
I’ve not been involved for a while, but have flarm effectively said they’re not fussed now? Have they written that anywhere?
I’m wondering if they do change the key whether they’ve undertaken to give it to the ground stations next time rather than it have to be broken. After all, there’s more than 1 set of ground stations using it.
FR24, Radar360,Atom, does ADSB exchange use it?
Btw, it’s quite easy to build your own flarm box, but I think flarm would come after you.
I’m surprised they’re not making it more awkward now the SD/SE2/Flarm solution is in place.
Does it suit them to have it rebroadcast now?
I detect a little bit of mischief making
. In fairness to PAW, they like everyone else decoding FLARM data will be paying a subscription to FLARM for that facility via some process. SkyDemon and others simply pass on that charge from FLARM and make no profit on the transaction. I have just been talking to Airbox, this morning, about their integration with FLARM and SkyEcho with RunwayHD which is about to go live using a similar licence arrangement.
We have also licensed the reception, decoding and rebroadcast of FLARM data for incorporation into the trial TIS-B transmissions in support of the Goodwood trial. Confirming that this is in place and therefore you can offer continuity of service is exactly the sort of regulatory hurdle that the Regulator will examine in allowing the incorporation of FLARM into a TIS-B broadcast.
I am resisting temptation to embark on the rebroadcast v direct reception debate but I would urge people to go and read all the caveats placed by the FAA on the TIS-B concept and why rebroadcast of ADS-B targets are not included in the ADS-B TIS-B broadcast.
In summary, direct reception of a conflicting target, that is close enough to pose a threat, will almost always offer an increased safety mitigation in comparison with any ground based reception and rebroadcast, for a variety of fairly obvious reasons.
