Description
- Multi-band RTK receiver with tilt compensation & pole mount adaptor
- Made in Austria
- Ultra compact and lightweight
- Tilt compensation
- Precise and fast, centimeter accuracy, fix in 2 sec
The "Pro" version has everything what the "Expert" has, plus additional pole mount, which gives the possibility for a classical use of the GLRM 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.

Return Conditions
To qualify for a refund under the 30-day return policy, all of the following conditions must be met:
- A valid Return Authorization (RA) number must be obtained prior to returning the product. Returns without an RA number will be refused.
- The RA number is valid for 30 days. The returned item must be received within that period.
- The RA number must be included with the return.
- Products must be returned in unused, unmodified condition (e.g., no scratches, alterations, missing parts, or signs of installation/use) and in their original packaging, suitable for resale.
- Shipping fees are non-refundable. Return shipping costs are the responsibility of the customer, except in cases of a product confirmed defective through RobotShop's troubleshooting process or of a verified shipping error by RobotShop.
- Refunds are processed within 7 days after receipt and inspection of the returned item.
- A €100 cleaning fee may apply to domestic robots returned in used or unclean condition.
- A 20% restocking fee may apply to large-quantity returns of items ordered specifically for the customer from the manufacturer or not part of RobotShop's standard inventory.
Return Exceptions
The following products are not eligible for return or refund under this policy:
- Used, damaged, or modified products — Items that show signs of use, wear, or alteration, making them unsuitable for resale.
- Consumables * — Use and wear-and-tear components, altered or depleted through use (e.g., batteries, belts, brushes, gears, filament, tires, disposable bags, lubricants, greases, waxes, etc.). Not eligible for return once opened or used.
- Perishables — Goods liable to deteriorate or expire rapidly. Not eligible for return.
- Sealed goods (health or hygiene) — Items sealed for health-protection or hygiene reasons (e.g., masks, gloves, odor-absorbing products). Not eligible for return once unsealed.
- Build-it-yourself products and items requiring customer assembly * — Including robots & kits, robot parts, and other products requiring assembly or soldering. Not eligible for return once assembled, soldered, or installed.

How to Request a Return Authorization (RA)
While the same return policy applies, these orders require a separate contact process for returns.
- RobotShop Fulfilled Orders → submit a support ticket from your account under My Support Tickets, or contact us through our Support Center.
- Marketplace Vendor Orders → submit a ticket from your account under My Marketplace Tickets to contact the vendor directly.
Note: Marketplace vendor products are normally labelled with SKUs starting with RM, and identified on the product page with the mention "Sold and fulfilled by [Vendor Name]".
