Build your own base station

RTK GPS/GNSS technology needs a base station that generates correction data, for the rovers to achieve centimeter lever accuracy. If you don’t have access to an online RTK correction service (NTRIP), you can build you own base station with one of our boards, as all our boards can be configured as rover or as a base. But how will you connect the base and the rovers? Choose one of our radio links to make your life easier.
