Our three very precise linear acceleration/deceleration sensors (along X, Y and Z axes) as well as three rotational sensors (around X, Y and Z axes) can be used on submarines as a complete autonomous navigation system as a back up for GPS for the following reasons:
Both above mentioned reasons lead to a need of a very precise and sensitive autonomous navigation system for submarines. Our sensors can be customized to any required degree of sensitivity for detection of immediate change in linear or rotational movement of a submarine.
Signals from sensors are collected and mutually processed in order to calculate moving trajectory of a submarine. This trajectory is then compared with GPS trajectory in order to find out how far off the autonomous trajectory is from GPS trajectory after certain increasing time intervals.
Autonomous navigation system then recalculates its trajectory and readjusts 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 submarine from its GPS coordinates. For example, after one hour of autonomous navigation of the submarine, the submarine’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 potential partner which would enable testing of this autonomous system and its speedier introduction to this very interesting market.
