Motylov K. Information technologies for rise of accuracy of aircrafts’ location and motion parameters definition

Research object - postflight redundant trajectory data processing processes which are brought to a common timing system. Research objective - enhancement of the aircraft's trajectory information processing accuracy. Research methods - redundant trajectory information processing with use of numerical methods of equations solution, apparatus of mathematical statistics and probability theory, and also a theory of matrices according to a specific of trajectory measurements. Result of the research is a mathematical apparatus which allows to enhance the accuracy of secondary aircrafts' location and motion parameters definition in 1,4-12 times depending on the redundancy degree and geometrical factor. Research newness consists in sequential realization of two methods of trajectory information processing: generalized method for spatial redundancy realization and adaptive linear smoothing algorithm for temporal redundancy realization. Technical characteristics. Algorithm doesn't limit the processing data flow. It depends on characteristics of measuring stations. The number of measuring stations has no limit. Research results implemented in National center of youth aerospace education in frames of scientific-educational project "Ukrainian youth satellite" (2007) and in educational process of Donetsk National technical university for students of the Radio-engineering faculty during teaching some special disciplines.
