Abstract

The task of identifying the parameters of the aircraft’s movement on the active part of the trajectory is characterized by several features associated with the presence of a limited amount of tracking data for individual sections of the flight. For the filtration studying an array of telemetry data containing the discrete values of the apparent velocity, the algorithm of filtering was developed based on discrete wavelet-transform. The technique of identifying the parameters of the aircraft’s movement was put forward on the results of telemetry in the absence of a priori data about the statistical characteristics of measurement errors and estimated parameters.

Keywords:

telemetry; identify the parameters of movement; mathematical model of the motion; the apparatus of the wavelet-transform; the filtering algorithm; methodology; accuracy of filtration measurements.
