In-flight GPS fix acquisition

Is this sentence true:

In-Flight Fix Acquisition:

  • ArduPilot continuously monitors GPS data during flight.
  • If a GPS signal is lost or if the initial fix was poor, ArduPilot will attempt to re-establish a fix.
  • This means that if a drone takes off and, for instance, flies into an area with better satellite reception, it can gain a GPS fix mid-flight.

I took off without GPS fix. Landed twice. Disarmed and armed but got no fix.
I got a fix in few seconds just after reconnecting battery.

It’s Copter 4.6, 1st GPS is uBlox set for GPS and Galileo, second (disconnected on that flight) is EMEA GPS
