Hi all,
At the moment I'm still struggling to get a good quality altitude hold. It's driving me crazy.
How easy it was to setup my DJI Naza!. Maybe my expectations are to high?
After establishing there's nothing wrong with my pressure sensor the hunt for good alt/pos hold continues.
Now my focus is on the quality of the GPS lock.
Can someone explain the relation between the quality of the GPS lock and the quality of the altitude hold?
My findings are:
My AQ controller gives a 3D GPS fix within a minute.
The first few minutes alt/pos hold sucks. Now and then the blue light blinks.
After about 5-8 minutes the Hacc and Vacc values drop down to about 0.5 m. The blue led stays solid.
Only then my quadcopter seems to hold altitude. I assume this means SBAS fix.
Is it necessary for altitude hold to have SBAS fix?
What kind of accuracy in alt/pos hold can you expect with and without SBAS fix?
Best regards,
Jan Willem
