The Seatronics SeaFOG is an Inertial Reference System (IRS) based on latest generation fibre optic gyrocompasses (FOGs) and micro-mechanical (MEMS) accelerometers in a single, compact package. The SeaFOG provides highly accurate Heading, Pitch, Roll, Heave, Rate, Acceleration and Geographical Position.
SeaFOG may be used in a wide variety of subsea and surface applications including Survey, ROV navigation, AUV navigation and for Metrology applications. When used in static survey operations SeaFOG does not require any external latitude inputs. If used on a moving vessel then a GPS derived external latitude will be required. SeaFOG features a rapid realignment mode. If the unit has not been moved significantly from it’s last location then re-alignment will be completed within 90 seconds.
SeaFOG has two output datastreams: one is a “Simple” RS232 output that is non-adjustable and which can be used to configure the “Flexible” output. The “Flexible” output is user-selectable between RS232 and RS485.
