Hi BenCham,
Thanks. I have been following this with interest, how do you retro fit a transponder to a drone already on the market? Is it purely done via software and the existing data link or does it require an installation of a chipset or something else? drones above 900 grams need to have one but regulations are not detailed at all on how to achieve this for drones already in the market.
Switzerland has not even started to adjust to the new European regulation, let alone the most complicated bit about the transponders. Switzerland will surely adopt the EU regulations, probably using the best of the 2 years allowed by the regulators for phase in...
Hi Simon
Since November 01 in France we must have a transponder, external or internal.
"DJI" has already integrated this function with a firmware update for some models (Mavic 2Pro, Phantom 4 PRO V2 ...).
I'm currently discussing with the developers of AUTEL, I said that now it's urgent for European users. I got the answer last night from AUTEL, they are preparing an update with the transponder function, but I don't know when it will arrive ....
Today, we can use external transponder to fly: "
Beacon Standard - Dronavia", but it costs 199 € !!!,
So, I prefer to wait because it's very expensive

Quite simply, if your drone weighs more than 800g, you must have internal or external beacon since November 01, 2020. The invoice is 135 € if the police catch you without a beacon !!
For the transition period, nothing is certain, maybe 2023, not sure...
If you want to read and translate the interesting page: "
Signalement électronique à distance : l’état des lieux, DJI, les balises externes".
Finally, it is possible that each country adopts its own law. So possible a European law and a law by country ... !!!
To start, you have to do a training, answer questions and then register your drone, I did it! "
After that ... good flight
