*based on 2-minute satellite tracking and 15-second cellular tracking
Most TracPlus devices support both satellite and cellular networks and automatically switch between these networks as appropriate to achieve the most accurate and cost-effective tracking possible while ensuring global coverage via the Iridium satellite network.
When a tracked aircraft or vehicle is inside cellular coverage, the device will transmit position reports at 15-second intervals over GSM (Global System for Mobile communications). As it moves outside cellular coverage, the device will automatically change to transmit position reports either at a slower reporting rate (usually two minutes), or FastTrac if selected.
Any messages transmitted inside cellular coverage are included in all of our plans, with no per-message or overage charges.
