CONSTRUCTION OF ACCESSIBILITY DOMAIN OF KINEMATICS PARAMETERS FOR ANGULAR MOTION OF A SATELLITE IN THE EARTH SCANNING PROBLEMS

In the paper the program trajectories of a satellite angular motion while scanning the on-ground objects and performing reorientation on some interval T are obtained. The algorithms for computing the program trajectories parameters in a class of quadratic spline functions are presented. They are proposed for a satellite reorientation from a given initial angular position to a fixed position for the prescribed period of time T under limitation of parameter values of program trajectories, restricted by capabilities of their technical realization. The construction algorithms for problem of accessibility upon angles (or angular velocities) at the end of time interval T are proposed.
