Iridium Short Burst Data
The SBD is a new data service that is designed for applications that wish to send data messages of a smaller size or with greater frequency than is economically possible with circuit switched data services, or where there is no terrestrial communication infrastructure available for applications requiring data telemetry.
SBD is intended for integration into vertical market applications, in industries such as Oil & Gas, Utilities, Transport, Agriculture, Environmental monitoring and Maritime. Remote applications send Mobile Originated SBD(MO-SBD) messages by using an Iridium 9522 L-Band Transceiver(LBT). The application microcontroller or microprocessor communicates with the LBT via AT commands over an RS232 connection. Once the application loads the message into the LBT and instructs it to send the message, the message traverses the Iridium satellite network to reach the Iridium Gateway. From there the message is transferred to the Internet and onto a host computer system. Here the message is stored in a database for further data processing. The maximum length of a MO-SBD message is 1960 bytes.The service is designed to provide a low cost 2-way packet data communication between remote assets, sensors or equipment and monitoring/control processes.
The service can incorporate a GPS signal, making it ideal for tracking and fleet management applications.
