Note
titleAttention:

Trimble 1 and Trimble 2 GPS Receivers are operated by ship's command only.

The sensor is essential device providing position data for a large number of scientific devices. Most sensors do not directly receive positions from GPS sensor but from motion sensor Hydrins.

The system TRIMBLE 1 / HYDRINS 1 and TRIMBLE 2 / HYDRINS 2 are alternatively sending positions to the customers. DShip is logging positions from both GPS receivers in parallel.

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.
