Description Iridium Communication System

The Iridum Satellite Transmission System consists of currently 66 active communication satellites which enable a worldwide data transmission coverage by a Low Earth Orbit (LEO) Satellite Network. The data transmission rate of 2400 baud is accelerated through the implementation of the compression-code AMBE (Advanced Multi Band Excitation).
SEBA IRIDIUM-Trans makes use of this technology - which makes it a modern, reliable and economic data transmission system.

The main component is an optimized transceiver which operates like a standard modem. Almost every data logger and sensor is suitable for the connection via the RS232 port and therefore integrable with all SEBA measuring systems.
The transceiver with the intelligent technique of is specially produced for the requirements of hydro-meteorological stations which makes it a unique solution for the transmission of monitoring data from (remote) field stations.
