Claim Text:
1. A maritime autonomous station keeping (MASK) interactive device, comprising: a communication module to receive a following ship reference point (SRP) generated by at least one differential global positioning system (DGPS) receiver on a following ship relative to a guide SRP generated by at least one DGPS receiver on a guide ship; a processor to: generate a plurality of fixed following reference edge points (REPs) relative to the following SRP representing a following ship hull, generate a plurality of fixed guide REPs relative to the guide SRP representing a guide ship null, and monitor a plurality of distances between the plurality of fixed following REPs and the plurality of fixed guide REPs, recommend a change in at least one of a following ship course and a following ship speed based on an error value between a measured variable and a desired setpoint as to the plurality of fixed following REPs and the plurality of fixed guide REPs, to perform at least one of an overtake maneuver and a station keep on an intended station; and a controller operable to automatically modify at least one of the following ship course and the following ship speed for correction of the error value, based on at least one of a recommended course and a recommended speed, wherein the controller optionally modifies at least one of the following ship course and the following ship speed based on a user input.
