The BigRedBee SBD allows you to send and receive short messages from anywhere on Earth with a clear view of the sky using the Iridium satellite network.  No cell phone / GSM / APRS or other radio service is required.  The integrated GPS and power management features provide a completely self contained system, no external components required. Extremely low idle power consumption means standby time are measured in months with a battery not much larger than the transmitter itself.

At just 1.5" x 1.5", the BigRedBee SBD is the smallest Iridium SBD system available in the world..
