Mobile Position Tracking in Three Dimensions using Kalman andLainiotis Filters

摘要

In this paper we present two time invariant models mobile position tracking in three dimensions, whichdescribe the movement in x-axis, y-axis and z-axis simultaneously or separately, provided that there exist measurementsfor the three axes. We present the time invariant filters as well as the steady state filters: the classical Kalman Filter andLainiotis Filter and the Join Kalman Lainiotis Filter, which consists of the parallel usage of the two classical filters.Various implementations are proposed and compared with respect to their behavior and to their computational burden: alltime invariant and steady state filters have the same behavior using both the proposed models but have differentcomputational burden.
