GL51B: Ultra-Compact BLE-Enabled GNSS Tracker for Covert Asset Monitoring
Micro GNSS Tracker for Assets, Tools, Equipment, and More
EasyNet Technologies proudly presents the GL51B from Queclink — a micro-size asset tracker built for discreet deployment, ultra-low power consumption, and reliable positioning in a wide range of asset tracking scenarios. Combining GNSS, BLE, and advanced power management in a device smaller than a matchbox, the GL51B is the perfect solution for tracking valuable non-powered assets, tools, and high-value goods in motion or storage.
Built for Smart, Silent Tracking
Despite its ultra-compact size, the GL51B is powered by an intelligent core designed for high precision, efficiency, and responsiveness. Whether you’re tracking mobile equipment, cargo containers, or warehouse tools, this device ensures pinpoint positioning without drawing attention.
Key Benefits
Micro Size with Covert Deployment
One of the smallest trackers in its class, the GL51B is easy to conceal in packages, equipment, or vehicle compartments — ideal for theft prevention, hidden tracking, or high-value asset monitoring.
GNSS + Base Station Positioning
Offers dual-mode location tracking:
- High-accuracy GNSS (GPS, Galileo, etc.) when available
- Cell-ID positioning fallback using cellular base stations in GPS-denied environments (e.g., indoors, underground)
Built-in BLE 4.2 for Smart Connectivity
Integrated Bluetooth Low Energy (BLE 4.2) enables:
- Peripheral connectivity (e.g., sensors, tags, readers)
- Proximity detection
- Wireless configuration or scanning
Perfect for IoT ecosystems and smart logistics.
Advanced Power Saving Modes
Designed for long-term battery-powered deployments with intelligent power management:
- Standby mode for minimal energy usage
- Scheduled Timing Reports to send location data at set intervals
- Power Saving Mode with wake-on-motion or scheduled wake-up
Enables up to several months of operation on a single battery.
Smart Event-Based Reporting
- Wakeup Report on movement or activity
- Low Power Alarm alerts when battery drops below threshold
- Dual-Mode Anti-Theft Alarm using both movement and BLE-based triggers
Ideal for anti-tampering applications and responsive security.
OTA Control and Configuration
Supports full over-the-air (OTA) configuration and firmware updates for remote fleet management. Save time and reduce the need for on-site service.
Internal Engine: Built for Intelligent Tracking
At the heart of the GL51B is a power-efficient MCU and GNSS chipset combo, purpose-built for asset tracking:
- High-sensitivity GNSS receiver for rapid time-to-fix and minimal power drain
- Low-power microcontroller with embedded logic for configurable behavior
- Secure firmware with encrypted communication support
- Integrated motion sensor for smart triggering and status reporting
This “micro brain” enables the GL51B to act autonomously, respond to movement, and communicate efficiently — without constant backend interaction.
Top Use Cases for the GL51B
Tool & Equipment Tracking
Attach to valuable tools or portable machines to monitor usage, movement, or theft.
Non-powered Asset Logistics
Ideal for containers, trailers, pallets, and cargo that need periodic location reporting.
Anti-theft Applications
Thanks to its small size and covert placement, the GL51B offers discreet monitoring of high-value assets — alerting on movement or BLE tag separation.
Industrial & Warehouse Environments
Track internal asset flow using BLE + Cell-ID location without relying on GPS signal availability.
