Greenvalley LiBASE - Advance RTK GNSS Receiver

Key Features of LiBase RTK GNSS Receiver

INTELLIGENT INERTIAL NAVIGATION READY TO USE

No leveling is needed at less than 60° inclination, points can be measured immediately, and the centimeter-level accuracy is maintained, and the measurement eﬃciency increases drastically.

LIGHTWEIGHT AND COMPACT FULL MOBILITY

At only 0.83kg with two batteries; it can be easily held with one hand and can be put into a pocket.

EXTREMELY FAST RTK INITIALIZATION AND GNSS CONNECTION SPEEDS

Built-in K8 series modules, based on a 5-satellite 16-band service, full GNSS global support, achieving ultra-fast ﬁxation; 40+ satellites are available at any location, greatly improving the ﬁxation rate in blocked environments.

INTEGRATED TRANSCEIVER POWERFUL FUNCTIONING

Full-feature RTK application, supporting radio, network transmission, and reception. Frequencies can be adjusted according to user’s needs, achieving compatibility with various mainstream protocols/RTKs in the industry.

Designed for Rough Site Conditions and Last for Life

IP67 Design;
Withstands topple from a 2 m survey pole onto hard surfaces.
