The PR-9000 model is the latest autopilot system from TOKYO KEIKI. The PR-9000 is designed using the latest technology from a wealth of engineering and manufacturing experience of navigational instruments.
It's series utilizes color LCD displays which greatly enhance the viewability of all navigational data, and system monitoring information is provided to assist the operator with selection of a back up system of operation when an abnormality occurs.
Track Control System(TCS)
TCS function is available as an optional operation mode of Autopilot with ECDIS. Once the operator creates a planned route on ECDIS, the vessel can follow the route automatically by selecting TCS mode on Autopilot. Autopilot PR-9000 calculates and corrects the ship's drift during TCS mode so that the vessel can maintain the most optimum route. TCS supports the highest level of navigation and safety by following the pre-planned/pre-checked route automatically and precisely.
Adaptive Control(NCT : Notable Control Technology)
PR-9000 can adopt TOKYO KEIKI's special control method NCT as an optional heading control method. PID (Proportional-Integral Derivative), well known as conventional heading control method on Autopilot, requires operators to manually adjust the environmental setting to accommodate the vessel's characteristic maneuvering motions and its external influences. NCT has been developed to make the vessel "adaptive" by automatically calculating the appropriate settings of those motions/influences by PR-9000's original algorithm.
(NOTE) The conventional 「Autopilot」 is now called 「HCS(Heading Control System)」in the SOLAS.
Route Control function(ACE : Advanced Control for Ecology)
ACE makes it possible to control a straight route with the PR-9000 without having to connect it to the ECDIS.
With Autopilot(HCS)
*4, the ship follows the direction of the set course and influence form tides or heavy seas can move the ship off course prior to arrival at the destination which in turn increases the navigation distance.
Due to this external influence, small steering changes must be performed in order for the ship to return to the original planned destination.
With the new Route Control(ACE), a route is automatically created on the heading between the current position and the destination, outside disturbances(tides) etc., are calculated, and the best rudder control is implemented making it possible for the vessel to sail on the newly designated route more efficiently..
When compared to Autopilot, reduced route deviation/ shorter sailing distance/ reduction of wasted rudder ultimately contributes to safe and energy efficient navigation.
*4:Conventional "Autopilot" is now known as "HCS" or Heading Control System in SOLAS.
