Methodology for Determining Deviations of Pilotless Aircraft from a Given Trajectory by Parallaxes of Underlying Surface Images

Purpose of research. Development a methodology for determining deviations pilotless aircrafts from given trajectory in conditions signals loss navigation satellites. Methods. The technique is based on functional relationship between deviation parameters and changes longitudinal transverse parallaxes overlapping images the underlying surface due to these deviations. Mathematical description computational procedures determination used methods functions approximation mathematical processing measurement results with accuracy estimation obtained results. Results. A that includes monitoring, assessing level magnitude direction was developed. system nonlinear equations describing parallax obtained. Linearization, normalization solutions this by least squares method were performed. Analytical relations posterior assessment Conclusion. provides detection uncoordinated an commensurate satellite methods. proposed approach makes it possible reduce number processed corresponding points dimension problem being solved comparison known This significantly reduces resource costs, which great importance use developed board miniature aircrafts.
