Thanks!Fair play!
However you aren't an " average farmer"
That is some seriou skill! You seem a new member, what's your background? Want a job
You would need either:Can somebody tell me if I would need two of these devices (one as base station, one as roving receiver) along with an iPad and an app to provide centimetre position information accuracy over an area of about a square mile?
Sorry if I'm being a bit thick but not really up to date with the technology but would like to be.
We have a vast underdrain network that needs maintenance from time to time. It would be nice to be able to record locations of drains and junctions accurately. It would also be nice to get rid of all of my drill bout markers using same kit. Is this kit a viable solution?
I guess the actual real world accuracy is the 64 million dollar question. The claim is cm class accuracy, but I haven't got any Emlid receivers so I can't tell you honestly!Thank you.
Any ideas of expected accuracy? I know a lot depends on many factors.
I am presuming that if I have one module as the RTK base then it needs more or less a line of sight to the roving module to avoid interference of the correction signal transmitted as a radio signal.
I presume you need to know the exact grid reference of the base and programme it in somewhere, so that it knows how to calculate the correction factor.
L2, which this system doesn't have, is what?
I need about 2cm accuracy, not the 20 to 30 cm accuracy I presently have with my basic system. I don't want to be paying big subscriptions either.
I am working my through the literature in the emlid website but am grateful for any simple explanation of the above questions.
TIA.
Very impressive!Following on from @Briantee 's work, I've been out drilling today with AgOpenGPS, modified to work with a hydraulic valve. Still a prototype so please don't judge! I do plan to condense everything into a nice box over winter... UBlox M8P L1 receiver and NSDOG2 IMU, corrections received over 4G through my NTRIP caster. Steering angle sensor is a potentiometer I nicked off the combine. Currently running the valve off a spool, but I plan to buy another valve with a compensating port so I can plumb it directly in to the load-sensing hydraulics.
It works impeccably! Especially since it cost me less than £2000 all-in.

Nice work! When you’ve figured out how to hack/code PVED-CL you’ll be ready to conquer the world.Well the AgOpenGPS project got a lot more exciting. Driving by wire is freaky but pretty fun, can steer the tractor with my smartphone over bluetooth! Next steps are to focus more on autonomous operation.
Contour is certainly the most challenging, but works pretty good. Overlap set to 10 cm. Going at 8 to 15 kmh. No crazy wheel whipping back and forth like most systems - more like hands free in a Benz. Milwaukee 18 V drill as steer motor. About 150$ total for auto steer hardware excluding gps.
I’m just playing catch-up. Up to 2014 nowPved-cl is so last year..........
Off topic, but I think the implications of the automation (r)evolution are pretty staggering...lots of occupations are in the cross hairs. What are we going to do with ourselvesI'm voting Briantee to stop here. It is OK to build applications that make farmers' life easier but now he is going to make farmers redundant.
Looking really good Brian!Another video on progress. Have headland sequencing of events, auto headland turning, headland generation based on boundary and touch, and much more. Project is getting really fun now!
