Satellite lock has nothing to do with compass calibration.
Compass calibration needs earth's magnetic field, that is, magnetic north, to complete successfully. Has nothing to do with satellites.
S switch function varies for the different phantoms which is just one reason why it's important to describe your aircraft fully before posting a question or problem.
But yes, on the P2 series Phantoms, the S2 switch can reset the home point by toggling it up and down 5x or more. The word is reset, because it will set automatically the first time you have GPS which will be moments after having acquired your sixth satellite.
So before flight, you should watch the AC or your app and wait for the home point to set. Flicking the S2 switch won't help. When it gets the 6th satellite, home point will set. You'll see an H on your screen or you'll see the AC flash green rapidly 20x AFTER the 6th satellite. If for some reason you cannot get the 6th satellite, you might consider launching (you'll be in ATTI) and carefully gaining altitude going straight up so to minimize the GPS Elevation Mask so that you get your 6th satellite and then your home point will set itself. You'll want to be directly over your desired home point when this happens - not over your neighbor's house, not over the ocean, etc. |
