Submarine Pool of Errors

Submarines operate in three dimensions across operationally diverse environments. A significant mission enabler is how much faith the Submarine crew has in their ability to maintain the safety of the platform and crew.

In its primary mode of operation, a Submarine typically functions without access to Global Positioning System data. From the moment masts and antennas are lowered below the waterline, the crew must maintain navigational safety through a variety of intensive navigation techniques, one of which is known as the Pool of Errors. The Pool of Errors is an expanding ellipse that quantifies a collection of errors for a specific moment in time. From the moment the Submarine loses access to GPS positional data, Submarine operators manually compute the axes and magnitude of four cumulative error sources: Fix, Log, Gyro and Set. These errors are used to provide a visual representation of the delta between estimated position and the truest calculation of the Submarine’s actual position. OSI Maritime Systems Ltd has designed a bespoke Submarine Electronic Chart Display and Information System that digitizes the algorithm used to generate a live representation of the Pool of Errors in real-time; removing the laborious computation process and significantly reducing operator workload.
