[QUOTE="Nuda, post: 7709480, member: 161743"] The f9p is the module I'm looking at but using it without rtk as a standalone receiver is <1.5metres accuracy which is useless, that's worse than guessing with the lime spreader. RTK does double the equipment but sub centimeter accuracy is much more preferable and if you get something like the one from gnss.store is offering with a integrated antenna and a magnetometer you now have a compact accurate GPS reading with another option for determining heading direction. 2x of those + 2x radio communication or cellular with some cheap boards (Arduino , pi etc) connect it to a android device and that's everything you need (bar auto steer) AgOpenGPS is very interesting with auto steer but using windows as the host platform is very questionable and there's almost nonexistent documentation. For me though auto steer isn't part of the scope for this nor do I think it is economically viable without a lot of development. All he wants is basic heading guidance, which frankly software wise should be extremely easy, draw a straight line, say how much you are left or right of that line. Plotting rows is more time consuming than actually difficult to implement. Once the data is there on a android (or windows ffs) device that's all the awkward stuff done. There are modules where sub meter accuracy is easily available at a very very low cost but I feel any sort of system that is 50+cm accuracy is a gimmick. It would only be useful on very large equipment where they are probably more than willing to spend good money on auto steer systems. I dunno how much of a market there is without auto steer and I've never actually seen it in use, trying to see if I can get one of the neighbors to let me see for myself. [/QUOTE]
