Base station/Rover with future use as autosteer

Background information: We’re new to agriculture and we’re also probably a little different than the norm here as we’re planting a pecan orchard which is a fixed crop as opposed to row crops, seasonal crops, etc… We planted 500 pecan trees last year or about 14 acres. The orchard will eventually be ~35 acres or ~1200 trees. No where near a large commercial setup, but a decent sized medium scale orchard in our area. As in everything, we try to minimize inputs whether it be time or money. I try and do everything myself, not only for the satisfaction of doing it, but also so I know how to fix it when it breaks.

So last winter I’m laying out the rows for the trees/irrigation using a combination of large 3,4,5 triangles, lasers, laser tape measures, regular long tape measures, optical transits, etc… I start trying to figure out how to do this faster. I figure larger pecan growers hire a survey crew to mark rows or trees. I ask an acquaintance who is large grower how they layout their orchards. He tells me autosteer tractors with a single shank plow on the rear. I’m jealous, but don’t have the resources to buy an autosteer tractor, but it sparks off the interest in me.

To lay everything out initially, I had briefly looked at Qgis, but it would have been too time consuming to learn for the benefits especially since I had trees coming shortly. After planting, I start trying to figure out how to do this faster. Well my googling triggered a facebook ad that guided steering with a lightbar on the front of the tractor hood. Shortly after I found AgOpen and fell in love with the concept.

I love the opensource concept and have experience with it in the machining world using LinuxCNC on a mill I bought. However, like all things new, this is like drinking from a waterfall. I’m hoping I can get advice on an intial setup I can use and learn from that will be useful for full autosteer later.

For my needs right now, a base station, as the closest base station in Texas is 150 miles away, and a mobile rover would what I’m looking for. I’d be inputting current locations of irrigation/tree rows, perimeters, etc. and make a layout. After learning with this setup, start on an autosteer system for the tractor for future planting/orchard operations.

Any suggestions for a base station and rover setup would be appreciated.

I’m defintely not a programmer by any means, but with instructions/youtube I can generally get by.

Thanks in advance for your time.

Welcome!

Good way is to start with wiki page, here: AgOpenGPS Documentation

It will lead you to whatever your needs are. For autosteer you will probably end up with AIO Board and RTKBase software with raspberry PI. Assembling is DIY, but you have to buy components online.

Here are some videos and official AgOpen youtube channel:

Thanks for the reply. I read the wiki and did many hours of research about 6 months ago, but have already forgotten much information. I had gone as far as building the AIO board on the JLCPCB website, but decided to wait until I had more time to dive into this. For the moment, I was looking for something easy to mess around with to start learning mapping/Qgis, but be able to use later on for the Autosteer system. I know I need base station, which looks to be the same no matter using the rover or the autosteer system.

I’ll probably end up answering my own questions the more I read, 1st the base station.

Base Station correction: over internet or through RF? I can get the antenna up fairly high, like 30’ pretty easily, but I’m not sure how well the RF signal will penetrate the trees later on. For the next 3-4 years line of sight should be easy enough, but eventually these will be big trees with fairly dense canopies. Maybe RF for early years just to make it easy and not have to deal with internet out in the field?

Looks like the easiest way to go about this is either ardusimple or sparkfun. Any advice on which direction?

For the base I would pick NTRIP if you have decent cellular coverage, otherwise radio (since it works for you at least initially).

Considering the base hardware, I’d choose the best documented and supported option:

You might save a bit choosing differently but I think that is a patch only for those who do not hesitate with all the details and who do not need to ask for advice here (assistance will be available though if you choose differently).

You can search for “tree planter” on the forum.
@KentStuff made a mod some time ago especially for trees.

Just placed an order with ArduSimple for receivers and antennas. Will get the rest of the components on Amazon or similar.
