GL Connect

GL Connect is the official companion app for full featured control and setup of RTK GNSS receivers GLRM and GLR from General Laser.

It provides a powerful and intuitive interface to configure, monitor, and operate your GLRM and GLR receiver across a range of professional applications including surveying, mapping, and construction.

NTRIP client included, right from your phone or tablet. Real-time accuracy for surveying, mapping, and geolocation on the go.

Configure your GNSS receiver, manage NTRIP connections, monitor RTK status, and capture accurate positions—all in one app. Location mocking feature in the Android app available.

Key Features:

* Instant Bluetooth Pairing: Connect quickly and securely to your GLRM device using Bluetooth Low Energy (BLE).
* NTRIP RTK Support: Configure and manage your NTRIP client to receive real-time correction data and achieve centimeter-level accuracy.
