The video above has made the rounds months ago and is a little 'loose with the facts'.
No such thing a commercial GPS satellites. They're all government owned. We have the same accuracy but the Gov't has additional safeguards against jamming.
Makes a lot of assumtions about when the ublox GPS engine has set a 'fix' point.
Just beacuse a cell phone jumps does not mean it has made an incorrect fix and is now correcting it. On your phone you're seeing real-time positionong as it acquires the 4 or more sats required for a valid fix.
This is probably why DJI wants to see 6 or more before establishing GPS/Atti. ready-to-fly.
