GV851CEU Queclink Vehicle GPS Tracker

Core Purpose

The GV851 Series is a programmable telematics gateway designed for connected vehicles and industrial systems. It acts as a central unit that collects vehicle data, connects external devices, and sends information to backend platforms. The open Linux environment allows flexible application development.

Connectivity and Communication

The device uses LTE Cat 1 with 2G fallback to support stable communication across different regions. This ensures data can still be transmitted when newer networks are unavailable. It is suitable for long-term vehicle and equipment deployments.

Positioning and Tracking

A multi-constellation GNSS receiver enables accurate vehicle positioning in different environments. Fast position updates support fleet visibility, route tracking, and location-based monitoring. This helps operators understand where assets are and how they are used.

Monitoring and Detection Capabilities

The built-in motion sensor allows detection of movement and vehicle activity. Ignition inputs and digital I/O support event-based monitoring such as start, stop, and operational status changes. These functions support operational awareness without complex setup.

Power and Environmental Suitability

The GV851 Series supports a wide 8–32V DC input range, making it compatible with standard vehicle power systems. A rechargeable backup battery helps maintain operation during power interruptions. The device is designed to operate across a wide temperature range.

Expansion and I/O Support

Multiple interfaces including CAN, RS232, RS485, 1-wire, analog input, and digital I/O allow connection to vehicle systems and external peripherals. BLE 5.2 supports nearby wireless devices such as sensors or accessories. This flexibility supports customised solutions for different industries.
