7.13.2 Radio Modem RTK Corrections

Figure 20: Trimble R4 Base Station
Base station radio modem RTK corrections require both a base station and a radio modem receiver. The base
station is set up at a fixed location and transmits corrections to the radio modem receiver that is connected to
the mobile Certus unit (the "rover"). The radio modem receiver and Certus unit must remain within radio range
of the base station to receive these corrections. The base station should be located no more than 50 km from
the Certus, and ideally closer. Advanced Navigation recommends contacting a local surveying company for
assistance setting up a base station.
