The RockSTAR Two-Way Messenger is a truly global communication device and tracking system that works far beyond the reach of GSM and WiFi networks.

The lightweight, rugged handheld device uses the Iridium satellite network to transmit messages (like SMS, social media updates and short emails) as well as your location, from anywhere on earth.


The RockSTAR System

Using the RockCONNECT app, you can turn your Bluetooth enabled smartphone or tablet into an extension of the RockSTAR, sending messages and making configuration changes.

Your RockSTARs positions are visualised on our easy-to-use web-based management system, called the Core.

  • Long battery life (over 2500 transmissions on a single charge)

How does the RockSTAR work?


RockSTAR and Iridium

The RockSTAR 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 the Iridium satellite network in seconds. The message is relayed to us from Iridium, and then we visualise the positions on an easy-to-use web-based system called the Core.

Depending how often the RockSTAR is set to transmit, the device can last for up to a year on its internal battery

About Iridium

Iridium is the only satellite network that allows transmission of information from any point on Earth – other networks have no coverage in the polar regions, and have intermittent or no coverage in other marine and land areas.

Iridium has 66 satellites in orbit around the Earth, allowing coverage anywhere on Earth 24 hours a day, 7 days a week. No other satellite network has truly global coverage. Messages sent via Iridium take just seconds to reach Ground Control HQ.
