Modeling of kinematic characteristics of the line of sight of a mobile antenna of a spacecraft when it is pointed at an information reception point

Within the framework of the general problem of calculating the kinematic characteristics of the mobile antenna of the spacecraft, the problem of the kinematics of the complex movement of the line of sight "Sc — IRP" ("spacecraft — information reception point") is considered. The solution of this problem is given, with the help of which the relationship of kinematic characteristics in the absolute and relative movements of the line of sight " Sc — IRP" is established in the form of theorems on the addition of its angular velocities and accelerations.
