SafePilot CAT ROT - Trelleborg Marine and Infrastructure

SafePilot CAT ROT - Trelleborg Marine and Infrastructure


The CAT ROT is a small and compact pilot unit primarily designed to connect to a ship's AIS pilot plug and transmit data via Wi-Fi to the Pilot’s tablet/notebook. 

AIS is primarily intended for information, but not navigation. The AIS data format available from the pilot plug does not provide sufficient resolution in heading, nor in a rate of turn. These parameters are, however, vital from a navigational perspective. In particular, if quality predictions are of the essence. 

The CAT ROT is designed to overcome the shortcomings of the AIS pilot plug data format by generating an accurate real-time rate of turn and providing the missing decimal readings to the heading data via an integrated rate sensor, intelligent processing and advanced Kalman filter integrated into the unit.
