The top 3 things I learned, are:
Trajectory. Real cool!
2 epochs, with 185 seconds, is close to 99.9% right, with maybe a bit of slop... +- .2'.
Had this very unusual occurrence today. Up until I saw this, I'd never seen a group with over 185 seconds be wrong either, but now this is the most I've ever seen.
The distance to last you see of 0.68' is to the previous RTK shot I'd stored on this point (it was only a group something like 2,14,1 so definitely didn't have a ton of confidence in it). I did store a PPK on that point and after processed it matched this 4,550,3 group.
When the 7,241,6 group was the lead group the distance to last was around 2.3' so it was up to 3' off the final good coordinate.
The spot I was in on this shot was in canopy, but nothing at all extraordinary compared to what we shoot every day. The only condition that was very noticeable, and I've always seemed to have trouble in it, was heavy fog and a very heavy humidity.
Has anyone else ever had noticeable trouble with heavy atmosphere and fog? It would seem to reason that both radio signals as well as the GPS signals themselves could struggle "getting through" this type of atmosphere.
It had to be the cause/reason for this first I certainly believe....
