Leica GR50 & GR30 GNSS Reference Server

Versatile solutions for today and tomorrow

The Leica GR50 and GR30 reference servers are primed for the constantly changing requirements of GNSS technology. Regardless of the application, rest assured all GNSS permanent and semi-permanent network installations are receiving and delivering highly accurate and reliable data 24/7 for many years to come. The GR50 and GR30 reference servers offer more than just a standard reference station receiver.

GNSS performance for today and tomorrow
For any application, meeting the highest requirements and working in the toughest environment. Designed with performance and the future in mind, the GR50 and GR30 feature the ultimate GNSS engine with 555 channels supporting all global GNSS constellations, such as GPS, GLONASS, Galileo and BeiDou, as well as regional systems, such as QZSS, NavIC and SBAS.

Interference is no longer a threat
Maintain continuous GNSS multi-frequency operation even in challenging radio frequency environments with SmartTrack+. Gain insight about the frequency power spectrum as is seen by the receiver, including all desired as well as undesired signals. Easily identify and mitigate unintentional or intentional interference sources.

Smart and reliable
The GR50 and GR30 support applications like RTK, static networks, single base stations, field campaigns, structural monitoring, atmospheric and seismic studies and offshore positioning. Reference servers are engineered for reliable operation with simultaneous and multiple interfaces for communication, power supply and data logging. The smart design of the on-board software RefWorx featuring optional apps as well as modular hardware offer highest versatility. This allows tailoring of each system per individual customer needs, such as multi-session RINEX data logging and FTP services, multiple RTK client connectivity, or a comprehensive Ntrip (Caster, Server, Client) solution.

Site Monitor and VADASE
Detailed information about movements of man-made and natural structures as well as real-time positioning solutions are provided to scientists, researchers and engineers. Engage three different application specific differential RTK and Network RTK positioning Site Monitor modes for your individual need: 

Reference Station to monitor the stability of a pillar / antenna of a fixed reference station

Monitoring to monitor stability of critical locations of dams, bridges, landslides

Network RTK to compute positions as on a rover, allowing to analyse RTK & Network correction service performance

Leica VADASE autonomously delivers instant information about fast movements as they may occur during natural disasters such as earth quakes. 

Complete, easy control and secure
Thanks to the comprehensive and user-friendly RefWorx web interface, both GNSS network beginners and highly experienced professionals have complete and easy control. Maximum benefit with minimum effort is achieved through wizard-style guidance configuration, automated firmware updates, plug-and-play connectivity, automated email notification or support of Simple Network Messaging Protocol (SNMP). Advanced user access management together with HTTPs and SSL encryption and integrated firewall provide a high level of security.


Leica Spider family solution
Reference servers are an integral part of the Leica Spider family, a suite of software providing RTK services for tailor-made solutions. Together these programs offer users flexible, adaptable and hassle-free operation for Network RTK and monitoring services.
