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 £17.00 per month (note that this can only be billed in GBP) 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.
With each RockSTAR unit you will receive:
- The RockSTAR unit
- A USB charger
- 0.3m USB cable
- Quick Start Card

Frequently Asked Questions
RockSTAR uses the Iridium satellite network. Specifically, it uses an Iridium service called ‘short burst data’ (SBD). You can learn more about SBD here. At the heart of RockSTAR is an Iridium 9602 modem.
Yes, you can use the device to send/receive short messages – either using the device itself, with pre-sent 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, via either email 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.
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’s unlikely 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, and so on – so 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.
RockSTAR units and YB units are both manufactured by Ground Control, 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.
