SHIP CONTROL SYSTEM Russian patent published in 2011 - IPC B63H25/04 

FIELD: transport.

SUBSTANCE: invention relates to automatic control of whatever ships. Proposed system comprises angular speed, wind and disturbance transducers, echo-sounder, magnetic and gyro compasses and satellite navigation device. There is also data acquisition device, computer and steering gear actuators. Additionally, system comprises storage device with authorised access to results of every control computation cycle. Data accessed, computer starts data processing to set control algorithm. Computation results are transmitted into ship actuators controls and memorised in storage device. Note here that records in odd cycle are made in one storage and, in even cycle, they are made in another storage. In every launch of program (switching on power supply, recovery after failure), computer analyses data in memory. With emergent completion attributes, further computation is performed starting from latest correctly memorised results. Correctness of results retention is ensured by authorised access to storage units and their alternation.

EFFECT: higher fail safety and ship control efficiency.
