The GLRM Expert RTK receiver from General Laser combines pocket-sized hardware with professional-grade GNSS accuracy. The GLRM device works seamlessly with Geolantis, giving field teams everything they need to start mapping assets immediately with powerful, integrated software.

A partnership for precisions

Accurate field data depends on two things: reliable hardware and intuitive software.
The collaboration between General Laser and Geolantis brings both together in a single, streamlined workflow.

General Laser delivers one of the most compact and capable RTK receivers on the market. Geolantis provides the mapping platform that turns precise measurements into usable, structured asset data. Together, they remove complexity from field operations and allow teams to move faster with confidence.

With the GLRM Expert, you get centimeter-level accuracy. When paired with Geolantis, you can immediately capture, visualize and export your data right out of the box.
