For IoT / M2M Applications
The RockBLOCK Plus is effectively the same device as the 9602 encased in a fully waterproof, ruggedized enclosure. It's being used in hostile environments all over the world, from areas at risk of wildfires to remote farms, rainforests to oil rigs.
For Tracking and Messaging Applications
RockSTAR, our first product, has undergone dozens of upgrades over the years and remains a completely dependable handheld tracking device. RockSTAR has saved lives and provides a lifeline of support for those in operating in inhospitable environments.

Iridium SBD Coverage Map
The Iridium satellite constellation is in Low Earth Orbit (LEO) which presents several benefits for IoT applications. The main benefit is latency; as these satellites are much closer to Earth than satellites in geostationary orbit, the ping time is typically less than one second.
The Iridium satellite network is also ideal for mobile applications, as antennas are omni-directional, and do not need to be pointed; their data will be accepted by the passing satellite and then ‘handed off’ to the next satellite, delivering 100% seamless coverage.

Short Burst Data Service Plans and Pricing
For more information about our SBD Service Plans, please visit our dedicated Iridium SBD Pricing page.
Satellite airtime isn’t cheap, and we pride ourselves on delivering great value for our customers. So, rather than having a small number of plans that will either see you rack up expensive overage fees, or pay for data you don’t use, we tailor our plans to every customer. These are example plans only; let us know what your data requirements are and we’ll make a plan that suits you.
Also, please note that our annual plans are available for any SBD device; our Pay-As-You-Go plans are exclusive to Ground Control manufactured devices.
Our pay-as-you-go plans offer great flexibility for development purposes, and are available for the RockBLOCK 9602 and RockBLOCK 9603 plug-and-play satellite transceivers, the RockSTAR personal tracking device, RockFLEET vehicle tracking device, and the RockAIR aircraft tracking device.
Pay-as-you-go plans are made up of line rental and credits (see next tab – Running Costs). Line rental allows the SBD device to exchange information with the Iridium satellite network. Credits are used each time you transmit.
Line rental allows the SBD device to exchange information with the Iridium satellite network. Credits are used each time you transmit. One credit is used per 50 bytes (or part thereof) of message sent or received. One credit is also used if you check your mailbox and there are no messages waiting (a mailbox check).
Be sure to check out our SBD Pricing page for full details of our Pay-As-You-Go service plans.
Comparing Satellite IoT Connectivity
It’s tricky to compare airtime services because so much depends on how much data you need to send, but as a rough guide, we’ve put together the following comparison points. Get in touch if you’d like any help deciding what will work best for you.
