APPLICATION OF STATISTICAL ESTIMATION TO THE DETERMINATION OF OCEAN CURRENT-METER DYNAMICS.
Abstract
The possibility of storing inertial measurement signals from an instrumented current-meter in ocean environment on analog tape and then subsequently process the recorded data in laboratory using a general purpose digital computer, enables the design of a fairly elaborate optimum estimator for deriving position and Euler attitude angles so that precise current-meter dynamics can be obtained. The theoretical analysis presented in this work is directly applied to a real case problem for which simulation results are discussed. A first part of the thesis presents the particular oceanographic problem of concern and the method of data collection using a strapdown inertial system consisting of three rate gyros and three accelerometers. It also introduces the concept of statistical estimation techniques applied to the processing of instrument data. (Author)
