Hi have a few questions.
But first I wish to say this is not about how to calibrate (that is covered well in wiki and GCS) but about values and sequence.
I also wish to say I have a 280mm quad with DJI gps and Revo that is very well behaved in gps modes ,PH, VR (although need to play around with tuning) and auto land.
First mag_transform values, I read elsewhere (can't recall where and can't find it again) that values should be between 0.85 - 1.05.
Mine are 1.17889........1.16664........1.24831 and have been 1.16113365,0,0,0,1.14655042,0,0,0,1.22270429
Both worked fine.
1. I understand that these values can give an indication of accuracy of mag calibration.
My question is what range of values should I be aiming at and why?
I always calibrate out in the open over oplink.
2. Calibration sequence,this is what I do.
thermal followed by board level then gyro, next
set home location then accelerometer then mag. calibrations.
Question is, does anybody have thoughts on order and why?
3. Every now and then board seems to lose mag calibration after sitting for a couple of weeks and need to
re- calibrate. Has happened at least 6 times in the last year.
Any idea why?
Finally had a quick look at Next (Next Downloads) before I dive in does anyone know if mag calibration or gps algorithms have changed ? Maybe this is not the right place to ask this question.
Thank you.
