Did a gps clock jitter test using persistance with corn.
I used google earth to define my location and when i was at 94°, 6', 14" W I put down an ear of corn. Then i went straight west and did the same at 94° 6' 15". I then repeated both locations and found that they vary over time by +/- 22 feet. It was the same for both points.
The midpoints should be the true locations. Next I'll do north and south. I picked up the corn. Deer would eat it overnight otherwise.
