Components

There are two independent systems installed, called TRIMBLE 1 and TRIMBLE 2. Both consist of an antenna Zephyr Model 2 Rugged. The receivers are of type SPS855. Antennas are installed on antenna deck above bridge. The two receivers are installed in scientific panel on bridge. TRIMBLE 1 is sending NMEA0183 telegrams to motion sensor HYDRINS 1 and DShip. TRIMBLE 2 is sending telegrams to motion sensor HYDRINS 2 and DShip.
