New Cubic Spline Interpolation Methods for More Accurate Inertial Navigation
Professor Peter Z. Revesz
Department of Computer Science and Engineering
University of Nebraska-Lincoln
Abstract: Inertial navigation is the problem of estimating the flight path of a moving object based solely on acceleration or velocity measurements. Inertial navigation is especially important when GPS sensors are not feasible, for example, when the moving object is a submarine deep in the ocean. Inertial navigation may also be used by different animal species that can sense acceleration or velocity to find they way. In this presentation, we consider several algorithms for the processing of accelerometer measurement data in order to estimate the flight path of a moving object, including its future locations. We present a novel algorithm that is an improvement of other cubic spline interpolation methods and is more accurate than the older methods in estimating flight paths.

Linear Robust Iterative Unbiased FIR Filtering

Abstract: Robustness is required from an estimator when a system operates under the uncertainties in not well specified noise environments. In this regard, the Kalman filter, which requires all information about noise and initial values, is not robust. Better robustness demonstrates the unbiased finite impulse response (UFIR) filter, which completely ignores the noise statistics, the initial error statistics, and the initial state. Instead, the UFIR filter requires the optimal horizon of Nopt points to minimize the mean square error (MSE). Note that Nopt can be defined in a way much easier than that used to define the noise statistics. In this lecture, we consider the most advances iterative UFIR filtering algorithms and compare them to the Kalman filter (KF). Better robustness of the UFIR filter is shown against errors in the noise statistics, temporary model uncertainties, and measurement errors. We show that errors in the noise statistics can dramatically worsen the KF performance under the uncertainties. Applications are given for diverse kinds of linear and nonlinear problems. An overall conclusion that has been made is that the UFIR filter is more accurate in real-world applications implying model errors, while the KF is best under the ideal conditions.
