I upgraded my Solo to the mRo GPS last night and flew it this morning. It took about 2 minutes to register any satellites, which seems ok for a first boot of a GPS receiver in a new part of the world. Then it started acquiring them rapidly. Before I knew it, 17 satellites. BUT... the solo controller still was reporting "searching for GPS." At one point I had 22 satellites locked in during a flight, which is so awesome. But then, I descended behind some tall trees and it dropped down to 17 satellites and the value turned red and started reporting "searching for GPS." What gives? That's better than any GPS satellite lock I've ever had on this thing, but with the rev B GPS, it would call it good at 8 satellites and not complain. Is there a quality to the satellites? As I understand, this thing now receive Glonass too. Is that a factor? Does the software somehow evaluate usability of the satellites to arrive at the red or white sat count?
