dc.description.abstract© 2019, Allerton Press, Inc.Abstract: Results are presented from an analysis of the temporal behavior of the background count rate in an energy band of up to several MeV for the γ-ray detectors onboard low-altitude satellites, using data of the AVS-F instrument as an example. The instrument was installed onboard the CORONAS-F satellite with orbital parameters of an altitude of ~500 km and an inclination of 82.5°. The temporal profiles of the background count rate in the equatorial orbit regions are approximated by fourth- or fifth-degree polynomials. The applicability of the approximating polynomials is shown for the instruments installed onboard satellites with orbital inclinations of up to 38°, allowing for the evolution of the Kp index in the preceding time interval of 12–24 h before passing the geomagnetic equator. In modeling the RHESSI data of October 27, 2003, at an initial orbital altitude of ~600 km and an inclination of 38°, a mean count rate value of 1017 ± 8 s−1 is obtained in the geomagnetic latitude interval ±5° in the energy range Е > 0.1 MeV (analysis of the data yields a value of 1094 ± 153 s−1).
