In regard to GPS signal, I think
@AnafiPilot1 got it right !
A few months ago I was testing my Android phone for GPS signal with an app made with the help of the European Community to check for Galileo satellite signals.
This app is called ‘GPS Test’. It gives you a vision of the sky above with all satellites and if your phone is able to use them or not, the signal quality...
I remarked my phone did catch much more satellite signals than the Anafi did.
On the specifications given by Parrot, the Anafi was able to catch 2 constellations : the American GPS and the Russian Glonass system.
Looking at the specs of the UBLOX M8 Gps chip that is onboard the Anafi, they say it’s compatible with the Galileo signal.
At the time Parrot launched the Anafi in July 2018, the Galileo constellation of satellites was not fully operational and for political reasons, the Galileo signal was not allowed to be used in some regions (the USA for example).
Now Galileo is more and more operational and precise, the laws have changed in the USA allowing Galileo early 2019... and there is an ANAFI USA on the shelves...to be used by first responders that are not really concerned by political debates.
They probably integrated the Galileo European Satellites constellation in the signal caught by the Anafi with this update. Some mention they have GPS problems with the new update. I’d be curious to see if they are located in the same regions.
Parrot did not communicate on the subject... but if the GPS algorithm is region related (Like the WiFi frequency)... there should soon be a new FF6 update ;o)

There is an excellent article that summarizes political and commercial use of the Galileo system in the US here :
