Abstract:
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.
Keywords:spacecraft, line of sight, absolute and relative movements, angular velocities and accelerations, kinematic characteristics, information reception point.
