It's not a system for a farmer who has the local precision specialist on speed dial but if you're familiar with the tech it's the cheapest and most reliable method of sub inch accuracy. I'm feeding NMEA data to Agleader displays running Ontrac 2+ for steering. Two boards with antennas were less than $1000 and use any of the GPS constellations on L1 and L2. Lefebure NTRIP client can be used on your phone to connect to whatever you have in the cab. The SNIP software they recommend is free to use for a single caster. Obtain a highly accurate position of the antenna we use to set a ‘Fixed Mode’ on a receiver. Pass the raw data to a processing center for PPP. Gather 24 hours worth of raw GNSS data from that antenna. They will host your Ntrip caster for free as long as you allow it to be open for anyone to use. The PPP process works like this: Install an antenna in a fixed location. I use an Emlid Reach RS 2 placed on a known point and then use Emlid's free Caster software to send out corrections over NTRIP. Some NTRIP and VRS service providers can give you a Simcard that pretty much auto connects to the service.
