[QUOTE="Pheasant Surprise, post: 6495054, member: 1103"] There’s two main distance related functions you need to consider with RTK... [B]Radio Range.[/B] If using (UHF etc) radio to send out your RTK corrections, the radio range will be the first thing to disappear. That’s why folks build masts or stick a pole on the tallest shed in the yard with an antenna, to blast out their corrections. Blast is probably a bit of strong description, but you can get high power radios that will do 15 miles no probs in good terrain. [B]RTK Baseline[/B]. This is effective “GNSS operating range” - the practical limit beyond which its hard to get a “ fix” and also the precision error degrades too much. With agri using dual frequency receivers, you’re looking about 50 to 60 km from the base as the “practical” max workable distance, beyond which your position errors just get too high on RTK. (Note also that NTRIP - corrections delivered over the internet, usually last leg to the tractor is by cellular/mobile connection - has no radio distance limit - just the RTK baseline you need to consider) I’ll cover the business case angle in another post.
