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

Frequently Asked Questions

What satellite network does the GV75MG SAT use?

The GV75MG SAT uses NTN-IoT (Non-Terrestrial Network IoT) satellite connectivity on bands B23, B255 and B256. This is a standards-based Low Earth Orbit satellite system that provides global coverage including at sea and in remote areas where terrestrial cellular networks are unavailable.

Does the GV75MG SAT use cellular or satellite by default?

The GV75MG SAT primarily uses LTE Cat M1/NB2 cellular when available, automatically switching to NTN satellite when cellular coverage is lost. This approach keeps data costs low in coverage areas while ensuring continuity in remote locations — combining the best of both network types.

How long does the backup battery last on the GV75MG SAT?

The 1,100mAh rechargeable Li-Polymer backup battery provides up to 2,630 hours (approximately 109 days) of standby time without external power. At a 5-minute reporting interval this reduces to around 39 hours, and at 10-minute intervals approximately 126 hours. The device also features a zero power consumption mode drawing less than 0.4mA at 12V when the ignition is off.

Can the GV75MG SAT be used to track ships?

Yes, the GV75MG SAT is specifically designed for scenarios including ocean-going vessel positioning. Once a ship moves beyond coastal cellular coverage, the device automatically switches to NTN satellite connectivity to maintain continuous position reporting. It is suitable for commercial shipping, fishing vessels and other maritime applications.

Is the GV75MG SAT waterproof?

Yes, the GV75MG SAT has an IP67 waterproof rating — fully protected against dust and temporary immersion in up to 1 metre of water for 30 minutes. The 9–90V wide voltage input and rugged housing also make it suitable for outdoor installation on vehicles and equipment in harsh environments.

Is the GV75MG SAT locked to a specific platform or SIM card?

Confirm that your platform supports this exact model and its required protocol and features. Where a cellular SIM is used, the SIM plan, supported bands, operator coverage and device configuration must match the deployment.
