Hey guys!

So I was picking up readings in Static of GCPs for Drone Survey (about 30 of them, spread over 3 days) using my Sokkia GRX2. On Day 2, the base was accidentally moved by another person while it was still taking the reading. Because of this, the readings are obviously flawed, but the base was moved after about 3 or 4 hours (I have a 10-hour static reading of the point the base was on).

I tried to manually trim the duration of the base up until the time the base was fixed by breaking up the static to kinematic and eliminating all the readings after the time at which it was moved. I then manually fed the X, Y and Z of the point to the trimmed base that I know and processed it. Even after this, the error I'm getting on the Drone RMSE Report is over 50 cm. I need to get it under 5 cm.

I was wondering if there's something I'm missing? Because it seems as if even after trimming the base duration, the base is still taking in account the entire duration it was placed, instead of just the trimmed duration.

I'm using Magnet Tools V3. Any help is appreciated!
