Why does the DJI Naza M v2 quad take a long time to warm up?

Question

Quadcopter

Anyone who has come across knows that the Naza M Lite does not have a long warm-up, but the M V2 does. This means that when you turn on the copter, it stands for a very long time (5-10 minutes) and the light indicates that it is "warming up". At this moment, you can not touch it, you can not move the sticks of the remote control. At the same time, there is nothing to do with the search for GPS satellites. When the warm-up ends, the search for satellites begins.
I wonder what exactly is going on there. DJI support writes replies. Why is this warming up the longer, the lower the ambient temperature? Why is it almost instantaneous when changing batteries?

Answer 1

The inertial navigation system is warming up. In Phantoms, this is treated by cold calibration - take the copter outside when it's cold, or put it in the refrigerator, and when it cools down, turn it on and immediately start the IMU calibration (place it on a horizontal surface and do not touch it).
