RockFLEET Marine-Grade Tracking and Messaging Device


The RockFLEET Tracker is a waterproof and ruggedized global tracking device designed for permanent installation aboard marine vessels and land vehicles. It has an optional LTE Narrowband unit, which allows it to use terrestrial networks when possible, automatically switching to the global Iridium satellite network when cellular is not available.

For permanent installation on ships, yachts, and vehicles

The tracker will wake up on a regular basis, obtain a position using the GPS satellite network, and then transmit that position back to Ground Control HQ using either LTE Narrowband/GPRS or the Iridium satellite network. We visualize the positions on an easy-to-use web-based viewer.

With Bluetooth and additional API / communications ability, it offers easy integration with modern cell / tablet applications for catch reporting etc. A paired Bluetooth device can send and receives short messages (like SMS, social media updates, and short emails); this allows for full two-way communication.

The combination of LTE Narrowband and Iridium provides a cost-effective and truly global method of tracking and communicating with your assets, wherever they are.
