Today a perfectly clear day and I went to my usual spot. This place is a wide open park with no buildings or other obstacles in my way. I fire up the controller and drone (P3S) along with Litchi app and wait. Best I could get was 8 satellites. Over the past 2 weeks in the same area the norm is 12 with a high of 13 and a (very seldom) low of 10.
I decided to try an other usual spot and see if there was any improvement. Here I got 9 satellites where the norm over the past few weeks was as above.
I decided to try my mobile app "GPS Test" to see what numbers I was getting at these location. In both case I would get readings of "16 in view, 14 in use" or "17 in view, 15 in use"
I cannot understand why today these numbers are so low. No way that previous days had better/clearer skies. Similar, maybe, but not better. So my questions are:
Does this drop in numbers suggest I need to recalibrate imu/compass/etc?
What happens if I am flying a Litchi mission and the satellite number drops below 8??? Does the mission stop and my drone drift away with the wind??
