I imagine a mostly autonomous land vehicle relying on GPS would also require RTK GPS, which does require an external source of the data. Some GPS receivers can receive that from satellites, but the data is encrypted and requires expensive commercial licenses or military grade equipment.
- BenjiWiebe 3y agoYou can generate your own correction data for GPS, using a fixed base station, and relaying the data over a radio link or through the cell network. Look up ArduSimple if interested how. Something like $400 IIRC (for the base station). Source: we are doing it, using AgOpenGPS (OSS autosteer) with RTK
- sgtnoodle 3y agoOh I know. I've plumbed RTCM3 streams over radios and cell networks aplenty as well. There's a real cost to setting up and maintaining a base station properly, though. Subscribing to a service is attractive if you're only operating a small fleet, which is sort of the point?
