Opis:: Tree-dimensional sea space visualization become increasingly form of ship's environment presentation in maritime navigation systems. Sonograms and echograms for instance, should create underwater space in 3D because the object (or submerge unit) accurate localization in 2D is impossible between sea bottom and surface. For surface navigation 3D vector charts can be observed mostly in combat systems or ship's bridge simulators for some years. This article presents 3D radar screen visualization possibilities for navigation radar.

Opis:: The article presents formulas describing the values of average circular error, the average coordinate values and their covariance in the function of gradient matrix elements of hyperbolic position lines. The classical formulas do not take into account the correlation existing between the measurements of navigational parameters, and therefore also the correlation existing between position coordinates. This is also why they do not fully describe the accuracy of determined position coordinates. This is particularly significant in the case of strong correlation between coordinates and in cases when we are interested in directional error.

Opis:: Position estimation in integrated navigation systems often calls for operations on nonlinear system models. Dynamics nonlinearity of an object, which position we want to estimate requires using special filters. The Extended Kalman Filter based on linearization of nonlinear functions is generally accepted solution. The paper presents the Unscented Kalman Filter based on Unscented Transform. Filter performance with comparison to extended Kalman filter is discussed on the theoretical base and simulation results showing accuracy increase are presented.
