This system is designed and priced for use by people who need to know generally where their ROV is located or want to hold a position in the face of currents or tether pull.<\/p>\n

A baseline system consists of an electronics stack and a sensor head containing piezoelectric elements and an inertial measurement unit (IMU). An upgraded IMU version of the head is also available, which has similar positioning performance but reduced calibration requirements.<\/p>\n

\n
\n
\n

The electronics can be packaged in the user\u2019s existing or new enclosure, or an optional Cerulean DVL enclosure can be used.<\/p>\n

\n
\n
\n

An optional GPS sensor is available, which can be used to easily initialize an ROV\u2019s position with respect to the standard latitude-longitude world coordinate system. If the optional GPS is not used, the user can provide initialization coordinates from their own GPS or other reference, or simply use the DVL\u2019s dead reckoning outputs relative to an arbitrary coordinate system.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n
