GLRM Expert

PRE-ORDER NOW!

Multi-band RTK receiver with tilt compensation. Made in Austria

The GLRM Expert edition is without the pole mount for classical use on a standard pole.

Ultra compact and lightweight

The weight of the GLRM is just 115 g, which fits perfectly in the pocket of your jeans!

Just magnetically attach it to the mobile device and turn it into a self-sufficient RTK system, which delivers centimetre accuracy for both static and dynamic applications.

GLRM is ideal for cm-precise georeferenced lidar scanning with a mobile device. Comes with an optimally positioned antenna. Compatible with iOS devices with 3D LiDAR scanning applications, it offers a range of 4-5 meters for detailed surveys.

All frequencies, all constellations

GLRM supports all GNSS constellations and offers triple frequency capabilities from each GNSS system.

With an access to more satellites and faster and easier solution convergence, GLRM is a uniquely reliable tool, especially in urban, forested, and generally challenging environments.

Additionally, in-built powerful IMUs on board guarantee swift tilt compensation.

Comes with a free app

We offer seamless device configuration on the go.

GLRM comes with a free app, which allows you to set up NTRIP and GNSS parameters (satellites system, update rate) to get started with the point collection and stakeout.

API for software integration with the third party fieldwork apps is available.

Tilt compensation

GLRM is ultra-compact but ultra-powerful: it corrects for angles of > 60 degrees, while remaining within 15-20 mm of accuracy.

With advanced tilt compensation algorithms on board, the GLRM ensures cm-precise data collection and real time tilt compensation in challenging positions.

Rugged

IP67 aluminium case

GLRM redefines reliability.

IP67 ingress protection class. 3D CNC milled aluminium case. Plastic parts out of glass fiber, reinforced polycarbonate. It is built to withstand any conditions!

Magnetically attached to the mobile device

Forget the cases, kits, and packages – from now on you only need to take your mobile device, magnetically attach GLRM receiver, and you have a fully featured RTK system for your surveying and georeferenced lidar scanning tasks.

No additional equipment needed!

Precise and fast, centimeter accuracy, fix in 2 sec.

GLRM provides real-time, centimeter-level accuracy, essential for high-precision applications. GLRM ensures sub-centimeter accuracy for static applications and 1.5-centimeter accuracy for dynamic use.

Perfect for both beginners and professionals who require utmost accuracy in their fieldwork, with minimum time and effort investment. Let our receiver do the job!

Wireless charging, long-range BLE

GLRM uses latest tech high end BLE components which enable correction data transfer over long distance between 2 GLRMs (you can use GLRM as both a base and a rover).

The battery life of > 10 hours is ideal for lasting and extensive fieldwork. An innovative design allows a single cable to charge both the device and an iPhone simultaneously, streamlining the user experience.

Best in class triple frequency high-gain antenna

When used for 3D scanning applications with mobile phones, RTK rover attached to a phone gets tilted upwards or downwards to ensure better data capture. This however affects the strength of the received signal. Problem solved.

With GLRM you no longer need to compromise between scan quality and RTK precision. GLRM antennas are initially pre-tilted by 45 degrees, the optimal antenna positioning. This means even if you tilt your device vertically or horizontally, the impact of the angle on the signal quality will be minimal.

Anti-jamming, anti-spoofing

Urban environments are packed with radio connections, WiFi networks, power generating facilities, and many other causes of artificially generated noise, mess up with your signal.

GLRM comes with a powerful technology on board which distinguishes between genuine signals and interferences, maintaining data integrity.

Minipole

GLRM is delivered with a pencil size minipole, enabling you to use it, like in a classical setup with normal pole. For point collection and stake out. When you place your GLRM with mounted minipole on a horizontal surface, the minipole is vertical, allowing you super accurate and long term static measurements.
