I’m using Trimble gnss on a 140m. Dual mast cb460 all the normal 2d sensors and a pitch sensor. Machine grades perfect going one direction but when I turn around and go over the previous pass in opposite direction blade is .10sh high consistently. GPS vertical error was .03 and pdop 1.3 the other day when this was going on. What would cause this. Any help is greatly appreciated.
