GPS fix required when calibrating airspeed?

I looked up every topic airspeed sensor , also I mentioned my problem here.
But I couldn’t solve it. And tricky question came to my mind:Does GPS fix condition is must when airspeed sensor calibration is making?

No, it is not required. Also, calibration is not required to see some values on airspeed readings. You need to see some values even from an uncalibrated airspeed.
