geo-Fennel Total Station FGS 1

Posted by Stephen Ferguson at

Unique GPS Set for multipurpose applications.

The geo-FENNEL FGS 1 is a robust receiver designed for challenging environments integrated into a compact device that is lightweight and highly portable.

The FGS 1 can track all current working GNSS constellations. By using a unique algorithm it can operate in RTK mode combining all GNSS constellation signals or by using a single GNSS constellation signal such as GLONASS or BeiDou. The strong anti-interference ability of the receiver makes it possible to work in any environment. The FGS 1 integrates a cutting edge GNSS board, Bluetooth®, optional UHF (Rx & Tx) into a compact system. The smart design positions the FGS 1 among the lightest and most compact receivers currently available. The system is open to third party applications and supported by MicroSurvey FieldGenius and Carlson Surv-CE field applications.
