Yes he is !
The problem is that the GPS signal is only 5 hz rate and the radar is 50 hz.
Its mean that radar is much more sensitive in speed changes.
We used this year rowflow and I have seen that many times the system getting the speed information from the radar.
In headland turns during slow down and rump up the system can get more accurate information from the radar than the GPS .
Just remember how much different can make 1/10 second in delays.
Can your GPS rate be increased? Receivers with 10Hz update rate have been pretty common for a good while now.
At 5mph, in 1/10 of a second, you travel 0.73 feet. If you came to an instantaneous full stop, and have a 10Hz GPS, that 1/10 of a second will cause you to miss the mark by 9 inches.
The fact the issue is presenting only at extreme angles makes me suspect the coverage option is not set to minimize skip (shuts off when row reaches 100% overlap) |
