Product Description
The Stonex SR02 is a high-power 2W radio modem designed to transmit RTK corrections from a GNSS base station to rovers with reliable performance over long distances. Its user-selectable transmission power ranges from 0.5 W to 2 W, providing coverage of up to 10 km. Fully compatible with external and integrated GNSS radios, it supports multiple protocols (Trimtalk, Trimmark3, Satel), modulation types, and channel widths for flexible operation.
The SR02 can be used as a transmitter, receiver, or repeater, extending RTK coverage in demanding environments. It includes a built-in Bluetooth module that transforms GNSS receivers into base/rover configurations without cables. A rechargeable 6,800 mAh Li-ion battery provides up to 8 hours of operation, and the integrated LCD display makes setup quick and straightforward. With IP67 protection, SR02 weighs just 0.79 lbs.
