Description
Summary:The paper considers several scenarios of parametric uncertainty influence on accuracy of system state vector components optimal estimation. The main attention in the simulation is paid to the analysis of the influence of this factor on estimation accuracy and convergence time. A large amount of simulation results on a complex object trajectory is presented.
