Book Description
This Fifth Annual Report summarizes work performed by the Smithsonian Astrophysical Observatory (SAO) for NASA Goddard Space Flight Center (GSFC) under Cooperative Agreement NCC5-368. The Agreement is entitled 'Constellation X-ray Mission Study and Support.' This report covers the period from October 1, 2002 through September 30,2003. The report summarizes the main areas of SAO activity. Most of the work has been done jointly with personnel from GSFC and Marshall Space Flight Center (MSFC). We describe SAO participation in these efforts. In spite of the work being mainly a level of effort, a significant amount of work was accomplished. Under the Agreement, SAO performed work in eight major areas of activity. These areas related to: 1) Constellation X-ray Mission Facility Definition Team and Study Management; 2) Science Support; 3) Spectroscopy X-ray Telescope (SXT); 4) Systems Engineering; 5) Travel in Support of the Work Effort; 6) In-house Management and Coordination; 7) Technical Readiness and Implementation Plan (TRIP) Report and Follow-up; 8) Industry Liaison and Study Preparation.

Mission Design & Implementation of Satellite Constellations
Author: Jozef C. van der Ha
Publisher: Springer Science & Business Media
ISBN: 9401150885
Category : Technology & Engineering
Languages : en
Pages : 435
Book Description
The papers contained in this Volume of Proceedings have been collected from an international Workshop entitled 'Mission Design and Implementation of Satellite Constellations' which was held in Toulouse, France, in November 1997. This Workshop represented the first international gathering of the specialists in this currently very active field of research activity. The initiative to organise a Workshop around this theme was conceived during the Congress of the International Astronautical Federation (IAF) in Beijing, China, in October 1996. On that occasion, the IAF explored concepts and possibilities for the conduct of small specialist Workshops and Symposia of current interest. Topical, interesting, and focused themes in the general field of space technology (both theories and applications) will be selected for these Symposia. They aim at offering a dedicated forum at international level for specialists and experts to exchange their views and experiences on recent and future developments within the selected theme. These specialist Workshops and Symposia supplement the comprehensive annual IAF Congresses which cover all aspects of space technology and draw a correspondingly diverse audience.

Application of Scheduling Theory to Spacecraft Constellations
Author: Christopher John Graham
Publisher: Universal-Publishers
ISBN: 1581120915
Category : Science
Languages : en
Pages : 99
Book Description
In this thesis we advance the state-of the practice in the Space Mission Operations domain by leveraging single spacecraft technologies along with classical scheduling frameworks and notation to create a scheduler for a constellation of spacecraft. We define a scheduling product that is focused on the problem of scheduling networked groups of spacecraft, called constellations. Within this thesis we show that the constellation schedule problem is a very complex problem, and the application of heuristics is one approach that allow us to schedule successfully. Our first objective, comprising chapters 1, 2, and 3, is to describe the spacecraft constellation domain and the objectives of the thesis. This background provides a foundation for understanding the constellation scheduling problem domain. Our second objective, comprising chapters 4, 5 and 6, is to provide a representation and description of the components of a constellation system, and a formal definition of the constellation schedule problem via existing formal scheduling frameworks and notation. Our third objective, comprising chapter 7, is to use these frameworks to allow us to deduce the complexity of the problem. Our fourth objective, comprising chapter 8, is to present techniques that allow us to leverage single spacecraft scheduling techniques to construct a constellation scheduler. Our final objective, comprising chapter 9, is to propose a scheduler architecture that satisfies a typical constellation scheduling problem.
