Interpretation of Force Vector Recorder Data Describing Buoy System Dynamics.

Abstract

The Force Vector Recorder is a self-contained recording instrument which measures three components of specific force (force-balance accelerometer sensors), two components of earth's magnetic field (flux gate magnetometer sensors) and water pressure (strain gage diaphram sensor). This instrument was mounted above the drogue in an ocean test of a drogued drifting buoy system. This thesis describes the theoretical background and procedures for determining drogue dynamics and Euler attitude angles from the sea test data tape. The resulting data are shown and discussed.
