So, a few days ago I was at sea when a thought hit me:
The reason why we keep the GPS antenna low on a boat is because signal reflection on the water causes errors in reading, the GPS signal bounces off the sea and hits an antenna placed high (on a mast for example), thus creating shadow signal and inaccuracy in positioning.
Could it be that similar phenomenon could happen when flying at certain altitudes over a flat sea?
I have flown a few times over water at different altitudes and always in moderate winds (rippled water so I would assume a scattered bounced signal) and never had a positioning issue, but I would love your thoughts on this.
On another note, I think it would be extremely useful to have some debug overlay with sensors/gps related values displayed on the screen.
