Mathematical Models and Methods of Observation and High-Precision Assessment of the Trajectories Parameters of Aircraft Movement in the Infocommunication Network of Optoelectronic Stations

Mathematical models of open and covert video surveillance of aircraft located in the area of airspace monitoring of the information communication network of optoelectronic stations are given. The models take into account both systematic errors of horizontalization and alignment of axes to the coordinate system of optoelectronic stations to the local meridian, random errors of estimating the coordinates of the location of optoelectronic stations in WGS-84: latitude, longitude, and altitude, as well as the errors of measurements of azimuth, elevation angle, and slant range from the optoelectronic station to the aircraft. The methods of high-current estimation of the parameters of the trajectories of aircraft motion as a result of the solution of overdetermined systems of linear and nonlinear systems of algebraic equations are considered. It is shown that the use of temporal and spatial redundancy allows to significantly increase the efficiency and reduce the bias of the estimations of the parameters of the flight trajectories.
