Iridium Interface
This section provides information on the Iridium satellite transmitter
communications option, how to interface the Iridium satellite
transmitter to the QML logger, and more specifically, how to use the
Short Burst Mode in binary transmission. Iridium transmission using
data calls can be used like any other modem.
Iridium is the only data solution with a complete coverage of the Earth
including oceans, airways, and Polar Regions. Iridium delivers the
essential communications services to and from remote areas where no
other form of communication is available. The Iridium constellation of
66 low-earth orbiting (LEO), cross-linked satellites operates as a fully
meshed network and is the largest commercial satellite constellation in
the world.
Short Burst mode (SBD) is a mechanism to deliver short data messages
over the Iridium satellite network to the Internet. Each SBD message
can be up to 1960 bytes in length.
