About RockSTAR

The RockSTAR Two-Way Messenger is a truly global communication device and tracking system. It allows you to send and receive short messages from anywhere on Earth with a clear view of the sky. It works far beyond the reach of WiFi and GSM networks.

The tracker will wake up on a regular basis, obtain a position using the GPS satellite network, and then transmit that position back to Rock Seven HQ using the Iridium satellite network in seconds. The message is relayed to us from Iridium, and then we visualize 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.

Running Costs

Line rental is paid in blocks of 1 month, and allows the RockSTAR to exchange information with the Iridium satellite network. You only pay for months in which you wish to use the RockSTAR. No annual contract is required. Line rental costs £15.00 per month and includes access to The CORE management system for monitoring your devices.

Credits are used each time you transmit. 1 credit is used per tracking position or per 50 characters of message sent or received. 1 credit is also used if you check your mailbox and there are no messages waiting (A mailbox check). Credits do not expire unless you do not use your account at all for 12 months. Credits are shared/pooled between all of the devices on your account

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 you, via e-mail or directly to your web-service.

What's in the box?

With each RockSTAR unit you will receive

  • The RockSTAR unit
  • A multi-country USB charger
  • 0.3m USB cable
  • Quick Start Card

How does it work?

RockSTAR uses the Iridium Satellite network. Specifically, it uses an Iridium service called ‘Short Burst Data’ (SBD). There’s some official info here. At the heart of RockSTAR is an Iridium 9602 modem.

Can the RockSTAR send e-mail or SMS messages?

Yes, you can use the device to send/receive short messages - either using the device itself, with preset messages, or by linking with an iPhone/iPad/Android device to send custom messages

Messages sent from the device itself are always sent to the group of people you nominate in the management system - i.e. any message will be sent to all configured responders, you can't choose a specific person

Messages sent via the Bluetooth link (using the Messenger app) can be sent to any destination, either e-mail address or cell/mobile phone number

In all cases, people can reply to those messages, via e-mail or SMS, and the messages will come back to either the device or the Messenger app respectively

Does the unit work indoors?

As with all satellite-based devices, the better view of the sky the unit has, the better it will perform.

RockSTAR units use two sets of satellites - GPS satellites in order to get a position fix, and Iridium satellites to transmit that position back to base. The GPS signal is weaker than the Iridium signal

Typically, if the RockSTAR is near to a window inside then it may be able to obtain a GPS fix and transmit, although it will take longer than normal, and will therefore use more battery power.

If the unit is deep inside a building then it is unlikely to be able to get a fix or transmit very well, and will therefore use up a lot of battery quite quickly. However, we have had devices transmit successfully from inside caves, fridges, under the seats of cars etc... it is possible, just not guaranteed, and not as reliable as usual.

As a rule, the better view of the sky you can provide for the RockSTAR, the better it will perform, and the longer the battery will last.

What's the difference between a RockSTAR and a Yellowbrick/YB

RockSTAR units and YB units are both manufactured by Rock Seven, and they are identical in terms of hardware.

The difference is in the management system access, 'The Core', which you get as part of the RockSTAR package.

RockSTAR, and the accompanying management system, are designed for corporate, government and fleet use - i.e. you have multiple units, and want to manage them all from the same screen, behind a secure login.

YBs come with a cut-down 'blog' which can display one tracker at a time and is ideal for individual adventurers or expeditions, but not for fleets of units.

In short, if you are looking for a fleet of devices then the RockSTAR is the correct choice. If you are looking for a single tracker for personal use, or you are looking to rent units for a short period of time, YB would be the correct choice.
