SOME METHODS FOR QUICKLY ESTABLISHING ORBITAL SYSTEMS,
Abstract
Presented is a review of the orbital transfer characteristics of four techniques for establishing orbital satellite systems and the comparison of these techniques on the bases of time to establish the system and propulsion requirements. The satellite systems which are to be established are restricted, in this study, to systems in which all the satellites are in one circular orbit and are equally spaced in central angle. It is assumed that all the satellites, as a group, have been placed into a low altitude circular parking orbit which is coplanar with the target orbit. Thus, the problem consists of transferring a group of n satellites from a low altitude circular orbit to a coplanar higher altituce circular orbit and ''spreading out'' the n satellites into an equally spaced (360 degrees/n) relative orientation. The four techniques for establishing the systems may be referred to as (a) the Phased Ellipse Method (Target Apogee), (b) the Phased Ellipse Method (Parking Perigee), (c) Hohmann Pinwheel Method, and (d) the Fast Pinwheel Method.
