Determination of Positional Accuracy and Error Modeling for moving Objects Tracking

Position refers to the spatial location of an entity. That is the determination of the site or place of any process localization. A positioning system is a mechanism for determining the location of an object in space. Technologies for this task exist ranging from worldwide coverage with meter accuracy to workspace coverage with sub-millimeter accuracy. The statistical positional accuracy of a moving object being tracked any2D positioning system. This paper describes the measurement technique based on determining 1D cross-track errors from a nominal path, and then using this data set to determine the overall 2D positional error statistics. This method evaluates vehicle tracking in a city and people tracking in a city using Radio triangulation principle. Rayleigh-Gamma model is proposed to describe the radial positional errors used to perform error modeling. It is shown that this model has a good match with outdoor field measurements.
