Chinese satellite's first in line for GPS lock?

Methinks Chinese satellite's are first in line for GPS lock now. Perhaps this is why it is taking so long for a lock? (I am a Mavic 3 owner in Ireland)

That's not how it works ... the GPS receiver communicate with all the satellites that's visible above it in no particular order.

A recent swop from GLONASS to BEIDOU might be why it takes longer than usual to obtain a decent amount of satellite lock.....??

But apparently this issue didn’t exist until the December FW update. So I’m not sure how much water this theory holds.

I doubt that's the reason ...

Both GPS, GLONASS, GALILEO & BEIDOU have global coverage nowadays ... here below how they are placed & spread right now ... check it here --> Live World Map of Satellite Positions

Instead of GPS + Glonass + Galileo like the AIr 2S has, the M3 has GPS + Gallileo + Beidou.
Even if you received zero Beidou satellites, you'd still have plenty of the others.

I’ve noticed the issue on the M3 since release date, when I updated the firmware I noticed no improvement.

Gotcha. I’ve never experienced the issue on my M3 (knock on wood), but I know a lot of others here have indicated that they didn’t have problems until after the December update. Definitely a strange issue.
