When Cellular Coverage Is Not Enough for Fleet Tracking
Cellular-based GPS tracking works well in most of the continental United States, but significant coverage gaps exist in areas that trucks frequently travel. Mountain corridors, desert regions, remote rural highways, and northern border areas often have limited or no cellular service. During these coverage gaps, cellular-based trackers cannot report position, driver status, or vehicle health data, creating blind spots in fleet visibility.
For operations in Alaska, northern Canada, remote western states, and other areas with sparse cellular infrastructure, these coverage gaps can last for hours. A truck driving Alaska's Dalton Highway has no cellular coverage for over 300 miles. Mountain passes in Montana, Wyoming, and Colorado regularly lose cellular service. Even Interstate 80 through Nevada has significant coverage gaps between towns.
The business impact of tracking gaps includes: inability to provide customers with accurate ETAs, inability to verify driver compliance during off-grid periods, delayed notification of breakdowns or accidents in remote areas, and incomplete data for route analysis and performance metrics. Satellite tracking eliminates these gaps by providing continuous visibility regardless of terrestrial infrastructure.
Satellite Tracking Technologies Available for Trucking
Iridium satellite network provides truly global coverage through 66 low-earth-orbit satellites. Iridium-based tracking devices report position, speed, and basic telemetry data from anywhere on Earth, including oceans, polar regions, and the most remote land areas. Orbcomm and Skybitz are leading providers of Iridium-based fleet tracking for the trucking industry, with devices costing $200 to $500 and monthly service at $15 to $40 per truck.
Globalstar satellite network provides coverage across most of North America and populated regions worldwide, though with some coverage limitations near the poles and in certain geographic areas. Globalstar-based tracking offers lower data costs than Iridium for operations that stay within its coverage footprint. The SPOT Trace and similar devices provide basic position reporting at $100 to $200 for hardware and $10 to $15 per month for service.
Starlink, SpaceX's low-earth-orbit broadband satellite constellation, is emerging as a game-changing option for trucking. Unlike traditional satellite tracking that provides only basic position and text data, Starlink provides broadband internet connectivity (100 to 200 Mbps) from mobile antennas. This enables full fleet management platform access, video streaming, and real-time communication from anywhere. Starlink for business costs $250 per month with a $2,500 antenna, but the connectivity it provides in remote areas far exceeds any cellular or traditional satellite option.
Hybrid Cellular-Satellite Tracking Systems
The most cost-effective approach for most fleets combines cellular tracking (which is cheaper and faster) with satellite backup (which provides coverage everywhere). Hybrid tracking devices use cellular connectivity as the primary communication method and automatically switch to satellite when cellular is unavailable. This approach provides continuous tracking at a lower cost than satellite-only systems because the majority of data transfers occur over the cheaper cellular network.
Orbcomm, CalAmp, and Queclink offer hybrid cellular-satellite tracking devices designed for commercial fleet use. These devices seamlessly switch between networks based on availability, with the transition being invisible to the fleet management platform. Position reports continue at the configured interval regardless of which network is being used.
The cost of hybrid tracking is typically $5 to $15 per month more than cellular-only tracking, depending on the amount of satellite data transmitted. For fleets that regularly operate in low-coverage areas, this modest premium eliminates tracking gaps that could otherwise last for hours. For fleets that rarely leave cellular coverage areas, the additional cost may not be justified.
Two-Way Satellite Communication for Drivers
Beyond tracking, satellite-based communication systems allow drivers and dispatchers to exchange messages when cellular service is unavailable. Garmin inReach and ZOLEO satellite communicators provide two-way text messaging through satellite networks. A driver stuck in a remote area without cell service can send and receive messages to dispatch, report emergencies, and receive updated instructions.
SOS emergency capability through satellite communicators can save lives in remote breakdowns, accidents, or medical emergencies. When a driver activates the SOS feature, the device transmits their GPS coordinates to a 24/7 emergency monitoring center that coordinates rescue services. This capability is invaluable on remote highways where a breakdown without communication could leave a driver stranded for hours or days.
Satellite-based communication for dispatch operations in remote areas ensures that load assignments, schedule changes, and customer updates can reach drivers regardless of cellular coverage. A dispatcher can send a route change or delivery update to a driver traveling through a cellular dead zone, and the message arrives through the satellite network within minutes.
Implementing Satellite Tracking for Your Operation
Evaluate your routes to determine the extent of cellular coverage gaps. Use carrier coverage maps (Verizon, AT&T, T-Mobile) to identify specific segments of your regular routes where coverage is limited or unavailable. If your trucks regularly travel through areas with multi-hour coverage gaps, satellite tracking provides measurable value. If coverage gaps are brief (under 30 minutes) and infrequent, the additional cost may not be justified.
For operations primarily within the continental US with occasional remote travel, a hybrid cellular-satellite tracking device provides the best value. The device uses cellular 95 percent of the time and satellite for the remaining 5 percent, keeping costs manageable while eliminating blind spots. Orbcomm and CalAmp offer hybrid devices that integrate with most fleet management platforms.
For operations in Alaska, northern Canada, or other consistently remote areas, Starlink or dedicated satellite tracking should be considered as primary connectivity rather than backup. The investment is higher but the continuous high-bandwidth connectivity enables full fleet management platform access, video communication, and real-time data that cellular-only systems cannot provide in these regions.
