Ships traveling from point A to point B generally want to take the shortest route without running aground. Setting aside such things as currents, weather, political conflicts, and other variables, this is not a difficult calculation when going from port-to-port, and plenty of preferred routes exist.
However, when the destination or origin is arbitrary – such as a refueling ship at sea trying to intercept another ship – this can become a complex problem. In those scenarios, thousands of shortest-route calculations must be done in a time frame insensible to a human, so speed in finding the shortest route is of the essence.
With this invention, Naval scientists have provided a method and system that quickly determines the shortest oceanic route between dynamic points A and B, using an oceanic routing system in which a computer implements spherical mathematics to calculate the shortest route. If B is not visible from A, the system uses an overlay of vertexes on the globe and navigates from vertex to vertex.
- Optimal routing saves fuel and time
- Other approaches such as a mesh overlay are computationally intensive and only approximate locations
