The W820 is a satellite communication terminal, specially developed for the control of W810 radio buoys.
The W820 uses Iridium* LEO satellities network (Low Earth Orbit satellities) , formed by 66 satellites orbiting the Earth. This satellite network provides continuous coverage of the globe (including terrestrial poles) providing a latency of messages less than a minute.
RS442 link interface allows to realize connections – between the apparatus and computer – also of considerable length (over 500 meters) and also in conditions of strong electromagnetic interference.
The W820 can be controlled through software dedicated to W810 radio buoy, operates independently and is recognized as a network interface device.
