Yes have the latest version in it now. That pic was from parked in the shed earlier, 12 satellites show out in the open. Config on f9p is done by Andreas setup. The spin I get now is like a really quick kink out to one side, it will move the tractor about 1m or more off the line then jump back on
Your either losing RTK signal, satellites, or comms with the gps unit. If you momentarily lose rtk signal it will jump.
Interesting. I think I’ll have to do a screen recording next time to try catch it happening.
If I move the age alarm down to 2 seconds would that catch it if its rtk dropping out? Theres another option right beside that called minimum frame pause with values between 40 and 90 msecs, would this be any relevance?
Is your antenna an old single band one, which one are you using?
HDOP 1.59 is telling me, antenna issue or no corrections or both.
It’s a new ublox one I forget the model number even though I was looking at it yesterday. I was parked in the shed when I took that pic so I’ll try outside properly today.

I think it is an CMPS14 issue. Some of them work very well, but some does the jumps.
I remember Baraki and others discovered it, while the one Brian have does not.
Found by search: CMPS JUMPS

I was beginning to suspect the cmps but that link more or less confirms it. I’ll get a new one and try it see if it’s any better.
Parked in the shed, yeah that would do it 
Haha yea perfect conditions, I had just moved it from one tractor to the other and was fed up and cold😅
The old systems had a hard time finding 6 satellites in perfect conditions, 5 in a shed still is impressive in a way.
It happens also with disconnected compass?
That sounds just like the problem I was or am having, except I’m using dual and no bno or cmps.
Would you check your acres at the top and clear applied area, and see when it does it if the acres are immediately in the thousands ?
Also take note what direction you are heading when it happens.
Edit:
Also mine runs just fine when no RTK is used.
I didnt run it for too long with compass disconnected, it was wandering a lot without it.
I wont be near it until tomorrow I’ll have a look back at it then, from what I remember the area measure was fairly good. It was happening going roughly NE and SW, all the ab lines were going the same way.
I had a CMPS and got the jumps. Then changed to BNO085 and the problem went away.
I’ve had problems with the area counter as well,running dual antennas. Some times it jumped like crazy and the counter said thousands of hectares. After I changed the esp32 the problem disappeared.
I would still check the gps rate. The last 2 I have up loaded with andreas config had 1hz rate
OK I’ll have a look at that as well, i haven’t had to open ucenter at all yet so i’m sure it’ll be an an adventure 
is there a way in AoG that displays the current hz?
Are you using your own base station ?
