On the Accuracy of a Method of Moments Approach for Displacement Decomposition into Elementary Movements

Abstract

In a previous work, we proposed a Method of Moments (MoM) approach for decomposition of a complex displacement into elementary movements. We found a good agreement between our results, based on application of the proposed approach on data from an inertial navigation system, and the results obtained by simply integrating the instantaneous acceleration. In this paper, we assess the accuracy of our method, in order to evaluate the impact of the number of the basis functions.
