RTK Networks: Cellular Modem Communication Technology

With advancements in GPS positioning technology, obtaining RTK quality corrections is becoming easier and more affordable. A personal base station, consisting of an antenna, receiver, radio transmitter, mounting structure, and a power source, used to be the only option for any RTK operations. With a personal base station, radio range is often limited to 1 or 2 miles, however, farmers that manage plots scattered over many miles typically re-locate their base station to accommodate fields spread over several miles. Now, cellular modems are capable of replacing bulky personal base stations by streaming CORS or Real-Time Network (RTKN) correction data via the internet to the rover unit.
