NE South Dakota Clark, SD | I have seen similar situations over the years. Usually it was due to some very bad GPS positioning. On more than one occasion I have seen it were after the plow jumped, it still showed it was 3 feet in the ground. Then the GPS corrected and showed it on the surface. RTK is not perfect. Solar storms can influence activities like this. The best thing you can do is be watching your screen. 99 % of the time everything works, but that 1 % is when you need to see what happened. |
