Aerospace Instrument-Making Annotation << Back INVESTIGATION OF ALGORITHMS FOR A SPACECRAFT SURFACE CONTROL SYSTEM BASED ON PIEZOELECTRIC SENSORS K.E. Voronov, D.P. Grigor’ev, A.M. Telegin A brief overview of algorithms for determining the location of the impact of cosmic particles on the body of a spacecraft is given. A functional diagram of a device that records the moment of impact of particles on four sensors has been developed. The description of the experimental model for conducting research on measuring the coordinates of the impact site is given. An algorithm is proposed for measuring the time of appearance of signals from each sensor, using the Hilbert transform and correlation analysis. The errors of the experimentally measured coordinates are given according to the correlation analysis data and the threshold measurement of the signal appearance time. The results of the work done are summed up, the advantages and disadvantages of the applied methods are noted. Keywords: spacecraft, piezodetectors, micrometeoroids, space debris, particle registration, correlation analysis, experiment. DOI: 10.25791/aviakosmos.1.2021.1200 Pp. 40-50.
