Overview

About the eRTK30 GNSS Receiver.

The eSurvey eRTK30 is a visual GNSS RTK receiver built around dual-camera technology, so surveyors can measure a point without physically standing on it. Its visual survey mode extracts accurate coordinates from images and video captured in seconds, ideal for points that are unsafe, obstructed or signal-blocked. CAD AR stakeout projects CAD drawings straight onto the live camera view, so a whole design can be set out without picking points one at a time.

With 1,408 GNSS channels, a 60 degree IMU, worldwide 4G and a built-in transmit-and-receive radio, the eRTK30 is a high-end rover or base for demanding construction and survey projects.

Why It Works

Built to make the job faster.

Visual survey

Dual-camera technology computes coordinates from captured images and video in seconds, so you can position unreachable or signal-blocked points without physical access.

CAD AR stakeout

CAD drawings are marked directly on the live camera view, so there is no need to select each point individually. A fast way to set out complex layouts.

Calibration-free 60 degree tilt

A MEMS tilt sensor measures accurate points while standing or walking, with no pole levelling, up to 60 degrees.

Full multi-constellation GNSS

1,408 channels track GPS, BeiDou, GLONASS, Galileo, QZSS, NavIC, SBAS and L-Band for reliable fixes everywhere.

Global 4G and TX/RX radio

A built-in 1 W transmit-and-receive UHF radio handles base or rover roles, while a worldwide 4G modem covers network-RTK corrections anywhere.

13-hour battery, rugged build

A 13,400 mAh battery gives up to 13 hours of visual work, in an IP67 body with a 1.1 inch colour screen and full web UI control.
