    AgOpenGPS info

    We were wondering if anyone is using the agOpenGPS technology. It has been mentioned a few times and is it working for people?

    Thanks

    Most farmers are way too rich in North America to bother with open source and DIY. While in other countries, especially Europe, Africa, Asia, Russia etc it is used a lot. They have much smaller and less costly equipment, so it makes more sense.

    It now has NTRIP client into it as well. But there again, farmers here have to pay $20,000 for an unlocked RTK system and subscriptions of another couple thousand $, Mostly because they have to as the metering etc is all built into the GPS and console.

    Europe has the distinct advantage of tons of towers for correction basically free or next to it, an infrastructure severely lacking in Canada especially. Or they just chose to use a 200$ F9P ublox as base RTK, a free snip caster, and then free AgOpenGPS pulling GPS from another 200$ ublox and basically free autosteer at cm level precision.

    But AgOpenGPS, what people all over the world use, is merely a by product of its original goal which is to run a self driving tractor. There is no commercially available software for that.

      WD9, how does the ublox base communicate with the rover? Does it need to be over IP or do they offer some kind of LoRa radio communication between them? Thanks again for all your hard work on this!

        ArduSimple has a kit, 2 of the new dual frequency ublox GPS receivers, Xbee transmitters for 10 km claimed (probably a couple km in reality) antennas for 1000$. So that would use just radio connection from the base to the rover.

        The other way is as you say, having the base spit out its RTCM correction to a server and on to the internet, and a cell modem receiver in tractor/rover. The NTRIP client in AgOpenGPS takes the corrections from the internet and sends them via the serial line connected to the gps rover.

        So its, ublox F9P as a base to a "Snip Caster" connected to the internet. The NTRIP client in AgOpenGPS takes the correction from the internet and sends to the ublox F9P as the rover and corrects its position to within a cm and voila, you have RTK. (Like towards the end of the video where I use my home network instead of using the internet/cellular network - but its just a network)

        Hope this helps!

          Absolutely! thank you, seems very affordable.

            One thing farmers could do in communities is build their own correction bases - either just one or a bunch at other farms together. Its actually quite simple, and very inexpensive.
