SafePilot CAT ROT XT - Trelleborg Marine Systems



The CAT XT combines the ROT of CAT ROT with the dGPS precision of CAT I in one unit. The unit is intended for use in sets of two interchangeable units of which one is connected to the AIS pilot plug and the other is placed on the bridge wing as dGPS receiver. When connected to the AIS pilot plug the unit allows for charging of the internal battery and the dGPS function is disconnected making the unit work purely as an ROT sensor. When the unit on the bridge wing is running low on battery the two units are swapped for charging. This makes the CAT XT ideal for use on long transit pilotage operations.

The CAT XT represents the latest state-of-art that combines the CAT ROT rate sensor and CAT I GNSS receiver into one unit.
