Meridian M5Plus

Pocket-Sized IMU-RTK GNSS

M5Plus GNSS receiver is an extremely lightweight, full-featured, intelligent GNSS receiver system equipped with an integrated full-frequency antenna and advanced multi-channel RTK engine, built-in radio, and 8GB internal storage, allowing users to attain accurate, reliable solutions. Its powerful RTK algorithm makes M5Plus easy to get fixed solutions in the most demanding environments, brings you to focus on your surroundings and not the bubble to measure the points that previously could not be measured, making your stake out more efficiently and conveniently than ever before with increased speed, safety and comfort and greatly improving your working efficiency.

Multi Constellation

M5Plus provides an excellent onboard real-time navigation solution with high accuracy. Multi-satellite signals (GPS, GLONASS, BEIDOU, GALILEO, QZSS, IRNSS, L-Band) are included.

Powerful IMU Feature

Equipped with 120° calibration-free IMU technology in a small body, extending the M5Plus’s application range to locations that traditional RTK systems cannot reach, opening up new horizons for product applications.

Palm Size

The palm-sized RTK (Real-Time Kinematic) system combines elegance with precision, offering a compact solution for accurate positioning on the go.

Powerful Battery

With 7.2V 6600mah and quick-charge capability, it supports you in working more than 26 hours and greatly saves your time.

Rugged Housing

IP68 waterproof and dustproof design and magnesium-aluminum alloy housing.
