Iridium Trans (Satellite)

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.

Monitoring stations equipped with an IRIDIUM modem can be retrieved either from a central standard PC with IRIDIUM Modem or with an IRIDIUM satellite mobile phone.

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 SEBA Iridium controller is specially produced for the requirements of hydrometeorological stations which makes it a unique solution for the transmission of monitoring data from (remote) field stations.

  • Worldwide data transmission coverage (incl. polar regions)
  • Robust Iridium modem design enables data transmission under any climatic condition
  • Permanent data transmission possible, no time-slots (-frames)
  • Current data always available
  • Communication with all SEBA data loggers
  • Time- & cost-effective modem and data transmission
  • Low energy consumption
