Abstract (English):
This paper presents the results of observations of giant pulses from the pulsar B0531+21 (the Crab Nebula pulsar) conducted at the Institute of Applied Astronomy of the Russian Academy of Sciences (RAS). The primary aim of the study was to establish a domestic monitoring service and compute the ephemerides for this pulsar. Observations commenced in mid-2023 using the RT-13 telescopes of the Quasar-KVO network, operating in the S, X, and Ka bands. To achieve the research goals, we utilized the VLBI (Very-Long-Baseline Interferometry) registration system along with specially developed software and algorithms for data processing. A monitoring service for giant pulses was created, providing weekly ephemerides of the pulsar for over one and a half years. The period and its derivative were determined separately by timing the main pulses and interpulses. The obtained results demonstrate a high accuracy of period determination, consistent with the data from the Jodrell Bank Observatory , with a root mean square deviation of 7 picoseconds.
