The Iridium9522B contains the equipment needed for on-demand, two-way communications using the Iridium satellite network. This network provides global data coverage that supports communication with Campbell-based stations located anywhere on earth, as long as they have clear view of the sky. The Iridium satellite network is particularly ideal for stations at very high-angle latitudes (greater than 70° North or South), high-altitude applications, and mobile applications, such as buoys or ships.

The Iridium9522B includes the 9522B modem with mounting hardware, a COM9522B modem interface, the cabling needed for configuration and connection to a datalogger, and an antenna with a mount. The 18017-L coaxial antenna cable is purchased separately to allow users to order the appropriate cable length for their application.
