HAYSTACK POINTING SYSTEM: MATHEMATICAL DEVELOPMENT FOR SATELLITES AND BELTS

Abstract

Satellites are implicitly completely described by their orbital elements. The conditions for going from the mean orbital elements of a satellite to osculating elements considering perturbations caused by the ellipsoidal earth, and then to celestial coordinates and their rates of change are derived. For belts, it is necessary to fix a point at which it is desired to direct an antenna. This is done by taking the intersection of a right- ascension half-plane, a geodetic longitude half-plane, a declination cone, or a time varying central angle vector with the belt. The equations for determining this point from the mean orbital elements and the intersecting surface or ray are derived.
