Small and Light Design
With only 580g magnesium alloy design, G20M is a powerful productive rover for surveyors in topographic and mapping, infrastructure and construction.
Full Constellation Tracking
G20M can track full constellation GNSS satellites: GPS, Glonass, Galileo and BeiDou. It maximizes the tracking to observe all visible and available GNSS satellite signals. With the aid of UGypsophila RTK processing tech, G20M, uses and locks more satellites, thereby performing better for real-time reliable data accuracy.
Fast-Charge Tech
G20M provides type-C interface and supports multiple fast charging protocols. Surveyors can charge G20M using portable phone battery anytime and anywhere.
Long Life Battery
With a buit-in large capacity lithium battery, G20M can last all day. Smart power button design can indicate battery level even in shutdown status.
Smart WEB UI Control
To provide a friendlier experience for first-timers and experienced users, we provide users with 2 kinds of WEB UI: Smart version and Professional version.
