I have been playing around with microcontrollers and have noticed there are some GPS receiver boards that can be used with them. I've considered buying one for experimentation but have not done so yet. Maybe a Winter Project.
I don't know if these use any form of correction such as WAAS. Without some form of correction I wouldn't think they would be very useful for farm applications. Probably good enough if you are in a car accident and need to report your location but likely not good enough for finding rocks or planting.
Some of those microcontrollers like the Ublox F9P and Unicorecomm UM980/981/982 are very accurate. The F9P especially is used in many commercial applications. Agra-GPS puts an F9P inside the CRG Deere globe replacements.
The models above support RTK and can connect to GPS (USA), GLONASS (Russia), GALILEO (EU), QZSS (Japan), and BEIDOU (China) satellites on L1, L2, and L5 bands. The F9P also supports WAAS, EGNOS (Euro version of WAAS) and QZSS (Asia version of WAAS).
A fully featured sub 1 inch RTK receiver and antenna combo is less than $400 these days and you can purchase them freely and connect them to your arduino projects.
Most GPS phone apps have options for external receiver and for passing NTRIP. I map my field boundaries with a Ublox F9P and phone app connected to my NTRIP base station.
AgOpenGPS uses those models for DIY tractor autosteer also. |
