description: This work is devoted to the study of the influence of the orientation frequency shift on the positioning accuracy of the GLONASS navigation system. For this, a model experiment was carried out aimed at studying the effect of a magnetic field on a laboratory rubidium frequency standard, which made it possible to calculate the necessary parameters of an atomic clock. Also, a universal algorithm was written in Python, which simulates the orbit of a communication satellite and calculates the errors of the satellite ephemeris. Calculations were carried out using the British Geological Survey (BGS) API, which is based on the World Magnetic Model (WMM). The results of the algorithm execution are presented in the form of the dependence of the satellite position error on time. The obtained dependence is also compared with real data on errors of the GLONASS system. The comparison is presented in the form of correlation coefficients. The influence of the orientational frequency shift of an optically pumped quantum standard on the positioning accuracy of the GLONASS navigation system is estimated. The subject of research in this work is the orientation shift of the frequency of the onboard atomic clock; the research method is the calculation of variations of the magnetic field in the satellite orbit with the subsequent determination of the orientational frequency shift.
