ABSRACTThe purpose of the report is to present wavelet technology used to improve the performance of trajectory and telemetry data. Modem methods of detection and exclusion of anomaly measurements, main matters of de-noising the measurement and multiresolution analysis of the signals based on wavelet transforms, are considered.Wavelet tools for analysis of measurements results are implemented by SEC SPbSETU in data processing program complexes, developed for the use at Russian trial space-launching sites. Practical capabilities of wavelet technology will be demonstrated by applied program, installed in the note-book PC for processing of GPS/GLONASS raw measurements.

The present paper is concerned with the issues of processing telemetry and trajectory measure ments obtained as a result of complex systems functioning. We illustrate the concept "complex systems" with the help of complex dynamic objects. The methods of processing which are introduced in the following are based on the most advanced and updated techniques in the areas of time frequency analysis, wavelet theory, and other adaptive approaches. Special attention is drawn to the problem of signal preprocessing, which is always crucial in practice.
