Queclink GV75MG SAT

Queclink GV75MG SAT — LTE Cat M1 and NTN Satellite Waterproof Tracker for Global Asset and Vehicle Tracking

The Queclink GV75MG SAT is a next-generation telematics device that combines LTE Cat M1/NB2 cellular connectivity with NTN-IoT satellite network support — enabling uninterrupted tracking coverage even in the most remote locations where cellular networks are unavailable. It can be deployed across a wide range of transportation scenarios including freight logistics, asset tracking and ocean-going vessel positioning.

The GV75MG SAT features a wide voltage input of 9–90V DC and IP67 waterproof housing, allowing reliable long-term installation in vehicles, trailers and equipment operating in harsh outdoor environments. Its 1,100mAh rechargeable backup battery provides up to 2,630 hours of standby time without external power. BLE 5.2 support enables wireless accessory integration including driver identification key fobs and identification readers.

As an authorised Queclink distributor in the UK, Tracking Hardware UK ships the GV75MG SAT directly from our London warehouse — with trade pricing available for telematics service providers, fleet operators and resellers.

Key Features

• LTE Cat M1/NB2 + NTN satellite — dual-mode connectivity combining cellular IoT networks with NTN-IoT satellite bands (B23/B255/B256) for truly global coverage including at sea and in remote areas

• IP67 waterproof housing — fully sealed against dust and temporary water immersion for reliable outdoor installation on vehicles, trailers and assets

• Wide voltage input (9–90V DC) — compatible with 12V and 24V vehicles, electric vehicles and a wide range of commercial equipment

• All-in-one GNSS — GPS, BeiDou, Galileo and GLONASS receiver with AGPS support and under 2m CEP accuracy for precise global positioning

• 1,100mAh rechargeable backup battery — up to 2,630 hours standby without external power, maintaining tracking continuity during power loss

• BLE 5.2 — wireless connection to driver identification key fobs, temperature sensors and other Queclink BLE accessories

• Configurable digital I/Os — 1 dedicated ignition input plus 2 configurable I/Os for digital input monitoring or relay output control

• RS232 serial port — for accessory integration and device debugging

• Driving behaviour monitoring — accelerometer-based harsh braking, acceleration and crash detection for fleet safety programmes

• Zero power consumption mode — less than 0.4mA at 12V when ignition is off, preventing vehicle battery drain during long parked periods

Typical Use Cases

• Ocean-going vessel and maritime tracking — NTN satellite connectivity enables ship position reporting beyond coastal cellular network coverage, providing global vessel visibility

• Remote freight logistics — combined cellular and satellite ensures uninterrupted tracking through cellular dead zones on long-haul routes across sparsely covered regions

• International asset tracking — global satellite coverage means assets are never lost when crossing borders or transiting countries with limited cellular infrastructure

• Oil, gas and energy sector — tracking of vehicles and equipment on remote oil fields, pipelines and energy infrastructure where cellular networks are absent

• Mining and heavy industry — continuous location reporting for mine site vehicles and equipment operating in remote areas beyond cellular coverage

• Construction fleet management — driving behaviour monitoring, geo-fencing and tow alarms protect high-value plant on remote construction sites

• Agricultural and rural fleet — wide voltage input and IP67 housing suit farm machinery and rural fleet vehicles in locations with poor cellular signal

• Emergency services and government — reliable dual-mode connectivity ensures tracking continuity for emergency response vehicles operating in all environments

• Stolen vehicle recovery — jamming detection, tow alarm and satellite fallback maintain tracking even when a cellular jammer is used during vehicle theft

• Expedition and specialist vehicle tracking — adventure, scientific and military vehicles operating in extreme or remote environments benefit from always-on satellite coverage
