Product Description
This is a AIR FORCE INST OF TECH WRIGHT-PATTERSON AFB OH report procured by the Pentagon and made available for public release. It has been reproduced in the best form available to the Pentagon. It is not spiral-bound, but rather assembled with Velobinding in a soft, white linen cover. The Storming Media report number is A960923. The abstract provided by the Pentagon follows: The on-orbit control of future communications satellite constellations poses a challenge greater than the sum of the challenges of controlling each component satellite. New approaches are required which result in viable control systems that are flexible, reliable, and efficient. These approaches must also have the capability to derive control commands targeted at maintaining constellation-level metrics, and not just individual satellite positions and velocities. In addition, a certain level of autonomy is desired in order to minimize ground station communication and activity, and to allow for quick, responsive solutions to on-orbit failures. This work develops and tests a new methodology for the automated station-keeping of satellite constellations. Three conventional station-keeping strategies are proposed and studied, with the use of a constellation station-keeping simulation, for their ability to address the requirements of satellite constellations. In addition, three Lyapunov non- linear control strategies are developed mathematically. Finally, three sets of simulations are conducted to analyze the control and coverage characteristics of the Ellipso constellation. The Automated Station- Keeping Simulator (ASKS), created for this project, combines an optimal n-impulse rendezvous element to provide automated station-keeping for a constellation of satellites using realistic satellite dynamics calculations on a distributed network of workstations.
