I would,like to have "Gps System" user's opinons/advices/comments (I dont need to know which system you use, the goal is not to denigrate/advertise a model/brand!!! ):
  • which functionnality is missing on your system.
  • which functionnality is badly working.
  • what would you enhance.
  • new idea, functionnality
  • ... others

this would may be give me some new ideas/concepts to develop... :)

thx

I've an ez guide 500, what id like is a not covered option, as in when i start a field and i press the coverage button it counts the total area covered but counts the overlaps twice, id like it if it told me the area that hasn't been covered as well. for those without a switch on a spreader etc. also on my gps the next swarth only come on when you leave the headland swarth for the first time. so it takes a bit of guess work going for the first a b line. i hope this makes sence.

hello marco.

thx for your feedback.
I understand well point 1; in my sustem, if headland contour is made, total field area, total area covered , totat area covered twice are displayed: so i will add the remaining area to cover (easy task);
if no sprayer controller attached (or if sprayer is commanded manually), there is a Virtual controller which shows/notifies the user when to open/close and shows the same area informations.

Regarding point 2, my english is not good enought to understand what you mean; what is "swarth"?;

regards

In ireland and some parts of the english speaking world a "swarth" is used to describe a pass of the machine. for example if i spray the headland of a field, i would say ive done the headland swarth. lets say i sprayed up the a b line, my next swarth would be either 1L or 1R. does this make sense? your doing a great job by the way, do you intend on selling units?

thanks for the English course :)
so i see what you mean. in my system ab lines and headland are independents. you can define several ab lines whenever you want and recall/use one of them whenever you want. headland contour is not mandatory. if headland contour is made, the system can additionaly:
  • calculate total area and so on,
  • avoid to spray outside the field, so while turning in headland, if boom flies over the neighbour field, sections remain closed.
  • can calculate and optimal path (based on ab lines) in order to avoid maneuvers (backward/forward) when using narrow implements (drill 3 meters in my case) and take in charge the full headland turn in automatic steering mode
  • draw an inner virtual headland at whatever distance you want in order to know when to start/stop seeding (this the most useful functionality in my case)

when an ab line is built/recalled, a predefined (by user, by default 10) amount of parallels are shown , so you can have a visual situation. I use it when praying at night in order to known when the next swarth is coming, because sometime it is really difficult to see it.

I had a version running with an imu, but results are not yet sufficient, too much emu drift over time; I think I should invest on a high grade emu instead of the one I use. however I already noticed that tilt/roll has a large impact on position accuracy (antenna is on the cab roof)

For RTK I'm looking at using https://emlid.com/reach/
they also have imu built-in but not yet implemented in software.

Was looking at using a Canadian version very similar to the software you have built.
If you needing some testing done my hand is up (me please)
If open source can you please send me a version.

Stef has just ordered one, and I have too :) I reckon with a few software tweaks this could be an rtk base station for 1/10th of what the commercial ones cost.

If I got it right, this receiver only makes use of GPS on a single frequency. For agriculture applications the receiver really should support more than one constellation on two frequencies.

Quite some time ago I read about the correction signal latency requirements but now I did not find any specs. Previously the requirement was something that could only be achieved with WIFI or similar. Perhaps this has changed?
 
If I understand you talking of using RTCM from just one reach.... not as I first thought, the 1 as base and the other as rover injecting into something like Trimble using serial.
If using a Trimble rover, it would need to be able to accept RTCM 3.x corrections (as well as CMR/CMR+/CMRx) for it to work with a Reach base.

To set expectations, this isn't a commercial/industrial quality receiver. The development team are totally open about this, see:

https://docs.emlid.com/reach/faq/

The receiver is based on a 72-channnel U-blox NEO-M8T chipset. As Northern farmer alluded to although this receiver supports up to 4 constellations (a max of 3 constellations at any one time) it crucially only supports a single L1 frequency on GPS, GLONASS. So it's ultimate accuracy will not be as good as an L1/L2 multi-constellation receiver, because it can't compensate for atmospheric/ionospheric effects as well as a dual frequency receiver can. The trade-off of course is cost. Dual frequency, multi-constellation receivers cost a whole lot more.

But for the price, it *could* be good enough.
