The RockSTAR Two - Way Messenger is a truly global communication device and tracking system.
It is a lightweight, rugged handheld device which uses the Iridium satellite network to transmit your messages, and your location, from anywhere in the World. More details »
The tracker will wake up every so often (e.g. every 15 minutes), obtain a position using the GPS satellite network, and then transmit that position back to Vismo secure servers 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 viewer.
The RockSTAR also allows short messages (like SMS, social media updates and short emails) to be sent using a paired Bluetooth device (such as a smartphone) and the Messenger app. This allows for full two-way communication wherever you are, even when out of mobile network range.
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.
