Our two very precise linear acceleration/deceleration sensors (one along X axis and the other along Y axis) as well as one rotational sensor around “Z” axis can be used on ships as an autonomous navigation system as a back up for GPS for the following reasons:
GPS signal may not detect imperceptible changes in the movement
Both above mentioned reasons lead to a need for a very precise and sensitive autonomous navigation system for a ship. Our sensors can be customized to any required degree of sensitivity for detection of immediate change in linear or rotational movement of a ship. Signals from sensors are collected and mutually processed in order to calculate moving trajectory of a ship. This trajectory is then compared with the GPS trajectory in order to find out how far off the autonomous trajectory is from GPS trajectory after certain ever increasing time intervals. Autonomous navigation system then recalculates its trajectories at these intervals with reset sensors’ constants so, that the autonomous trajectory matches as much as possible GPS trajectory.
This iteration process then gives an estimate as to the positioning difference of autonomously steered ship from its GPS coordinates. For example, after one hour of autonomous navigation of a ship, a ship’s coordinates may be at maximum 10m off from those given by GPS system.
While this autonomous navigation system is being developed, we are looking for a potential partner which would enable testing of this autonomous system and thus its speedier introduction to the market.
