Observations of giant pulses from B0531+21 at the Institute of Applied Astronomy

A high-precision monitoring service for giant pulses from the Crab Nebula pulsar (B0531+21) has been established, achieving period determination accuracy comparable to global standards. Over 1.5 years of observations using RT-13 telescopes in Russia's Quasar-KVO network revealed that timing main pulses and interpulses separately yields a root mean square deviation of just 7 picoseconds—on par with Jodrell Bank Observatory's data. The study demonstrates the feasibility of domestic VLBI-based pulsar monitoring, leveraging specialized software for real-time ephemeris computation in S, X, and Ka bands.
