The RockBLOCK+ 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. Maybe you want to transmit weather information from mid-ocean? Or use it to control your robot in the middle of the desert? Perhaps you need to communicate in an emergency, when other networks might not be available? RockBLOCK+ can help you.
RockBLOCK+ has a built-in power regulator and can accept between 9-30v DC. At the heart of RockBLOCK is an Iridium 9602 modem. The RockBLOCK hosts the 9602 and provides it with an antenna, and its power supply requirements. It exposes the modem’s serial interface via RS-232.
|Powered By||3m 9-30v DC input|
|Built in Antenna||Yes|
|Size||4cm high, 13cm diameter (+cable)|
|Waterproofing||IP68 certified (submersible up to 1m indefinitely)|
|Ideal For||External use|
Line rental is paid in blocks of 1 month, and allows the RockBLOCK+ to exchange information with the Iridium satellite network. You only pay for months in which you wish to use the RockBLOCK+. No annual contract is required. Line rental costs £12.00 per month and includes access to The CORE management system for managing your devices.
Credits are used each time you transmit. 1 credit is used per 50 bytes (or part thereof) 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, even if you are paying no line rental. Credits are shared/pooled between all of the devices on your account
Please note, whilst our pay-as-you-go tariffs offer great flexibility for development purposes, we know they are not suitable for everyone. If you are planning a large deployment of devices (100+) and are willing to commit to airtime contracts of 12 months or more, please get in touch. We have access to various tariffs which may suit you better.

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.
The sleep signal is internally pulled high on the RockBLOCK and RocKBLOCK+ products, so you can leave it disconnected if you want to leave the modem 'awake' all of the time.
To turn 'off' the modem, pull the line to ground.
If you are using the SBDRT command, and the modem appears to 'hang' when you issue the command, it is probably due to flow control configuration. The default state for the RockBLOCK and RockBLOCK+ units has flow control turned ON in the modem. When running in 3-wire serial mode, flow control should be turned OFF, which will ensure you get responses to your requests.
Use the command AT&K0 at the start of your command sequence. This turns flow control off, and should solve the problem.
RockBlock was used as a command and control module, to enable the ground team to send commands to the high altitude rocket when out of GSM coverage
The pupils at Sutton Grammar School made an ocean drifter to to measure wave parameters and currents. RockBLOCK sends the data back from the middle of the ocean.
Andrew Ashe together with Mikal Hart (author of the fantastic IridiumSBD library for Arduino) has successfully tracked a balloon, and been able to recover its payload thanks to RockBLOCK.
