Earth coordinate 3-D currents from a modular acoustic velocity sensor
IEEE Oceanic Engineering Society. OCEANS'98. Conference Proceedings (Cat. No.98CH36259)
MAVS, modular acoustic velocity sensor, measures 3-D flow components along four acoustic paths using differential travel-time techniques, removes the offset from each acoustic axis due to individual characteristics of the cabling and any electronic offsets, and rotates the corrected components into earth coordinates with a gimbaled two-axis magnetometer. In the present version of MAVS, the sensor is assumed to be aligned vertically to within 15. Three requirements had to be met to allow the
