Mars Pro Laser RTK
GNSS Receivers
Overview
The Mars Pro is an ultra-reliable GNSS receiver with a millimeter-level laser, enabling it to handle complex surveying tasks with unmatched precision — for example, in hard-to-reach, signal-obstructed, and dangerous fields. The device features a sunlight-readable OLED display and tracks 1668 channels across 60+ satellites. Key capabilities include up to 120° tilt with 2.5cm accuracy, IP67 waterproofing, and up to 20 hours of battery life.
