The GCX3 is a part of the Sokkia GCX line of GNSS integrated receivers. It features advanced constellation tracking, open format software compatibility and longer range base to rover communication.

“The GCX3 features the new second-generation POST2 (Precision Orbital Satellite Technology) integrated antenna, adding BeiDou, Galileo, SBAS, QZSS and GAGAN satellite tracking, in addition to GPS and GLONASS to ensure the best positioning availability,” says Charles Rihner, vice president of the Topcon GeoPositioning Solutions Group. “Building on the success of its predecessor, the GCX2, the GCX3 offers all of the lightweight, compact and ergonomic benefits — along with centimeter-accurate positioning — now with expanded satellite tracking capabilities.”

The Sokkia GCX3 is designed as an open source technology receiver. It features radio-free RTK operation via multi-channel, long-range Bluetooth technology. When used as a base station, one GCX3 may support up to three concurrent rovers at a range of more than 300 meters. Each receiver may be used as a base or as a rover.
