The Stonex SR35 external UHF radio modem is used to transmit RTK corrections from a base station, but can also be used as a radio receiver. In addition, the retransmission function can be activated, or the radio placed between a base and a rover increasing the coverage area of the RTK correction. Finally, the Network Repeater functionality allows the SR35 to receive an RTK correction through the integrated GSM modem and retransmit it through the radio modem (Bridge Functionality).
The radio has numerous settings that can define communication protocols, channel width and transmission frequency, thus full compatibility with other external radio modems or integrated in a GNSS receiver. For a simple configuration of the radio it is possible to use the PC software or the APP developed in an Android environment which allows a fast and complete management of the SR35.
