Аннотация: The aim of this article is to analyze the dynamics of the Linus satellite of the asteroid (22)Kalliope. New results have been obtained, and now they are being published. New observations of thesatellite were made at the Caucasian Mountain Observatory of Sternberg Astronomical Institute (SAIMSU) from October 2021 to March 2022. The obtained astrometric results are presented in the article.Based on the updated set of observations, the parameters of the satellite’s orbit were redetermined. With theaddition of new observations an increase in the accuracy of ephemerides is shown. A new attempt was madeto determine the precession of the satellite’s orbit caused by the compression of a rapidly rotating asteroid.The goal was to determine the dynamic compression of the central body. The entire observation intervalis divided into groups. From the observations of each group the position of the axis of the satellite’s orbitwas found. Changing the position of the axis gives the desired precession. Several case studies show thatthe axis position of such observation groups is determined very unreliable. The reason is strong correlationbetween the determinable parameters with limited observation accuracy. Ways of studying precession byjointly defining dynamic parameters based on all available observations have been identified.
