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.

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.
* Full GNSS Control: Select satellite constellations (GPS, GLONASS, Galileo, BeiDou, etc.), configure signal bands, and apply elevation and SNR masks to optimize your fix.
* Real-Time Status Monitoring:
* GNSS fix type, number of satellites, and position accuracy
* RTK status indicators with LED sync
* Battery level and temperature readouts
* Device firmware and hardware info
* Tilt Compensation (FW 1.7+): Accurately capture GNSS points with up to 60° of pole tilt using real-time IMU calibration. View compensated coordinates and heading directly in-app.
* Custom Configuration Options:
* Set antenna type, offset, and height
* Adjust position/satellite info streaming rates (1 Hz / 2 Hz)
* Personalize your device name for easier tracking
* Firmware Updates: Manual firmware update flow to keep your GLRM receiver running the latest features and fixes.
* 2D Mapping Interface: Visualize antenna and tilt-compensated positions on an OpenStreetMap-based view.
