Space Technology Proceedings – serie

This volume of proceedings contains papers presented at an International Workshop entitled Mission Design and Implementation of Satellite Constellations in Toulouse, France, in November 1997. This Workshop represented the first international gathering of specialists in this active field of research. The rise of satellite constellations during the 1990s is one of the most significant developments in the satellite commercial domain since the beginning of GEO (geostationary earth orbit) communication services in the early '60s. This text contains a total of 37 papers are presented on topics covering constellation mission design, mission analysis and simulation, orbit selection, constellation deployment, maintenance, services and operations. The papers should be of interest in view of the rapid evolution of satellite constellation applications in the fields of telecommunications, navigation, and earth observation. Real-world applications that are addressed include voice and data communications, navigation, and data relay services as well as earth observations.Specific studies and experiences are provided on many actual constellation projects for telephone, data messaging, and broad-band data communications services such as Iridium, Orbcomm, Skybridge, Celestri, Teledesic, among others. Constellations for navigation services (for instance the Global Navigation Satellite System or GNSS) and for earth observation applications (for instance SkyMed/Cosmo) are also addressed. Finally, collision and orbital debris risk issues associated with satellite constellations as well as the proposed mitigation measures receive notable attention. The unique and novel characteristics of satellite constellation systems have not only rejuvenated satellite system design but have also brought new life to classical flight dynamics disciplines such as orbital mechanics, station-acquisition and station-keeping concepts: all of these aspects are addressed in detail in this volume of proceedings. The book should be of interest to both engineers and managers who are active in the design and implementation of satellite constellation projects. Even a non-specialist reader with a fascination for technological developments may profit from reading this book.

The proceedings of the 3rd International Space Conference are important since they came in the wake of the official closure of the LDEF program. The main mandate of this publication is to continue the discussions on the effects of the harsh low earth orbit (LEO) environment on materials and structures and on ways to prevent and/or reduce them. In accordance with this mandate, the main objectives and important points in the book are to promote the dissemination among research organizations and scientists of experimental data and experience gained from LDEF samples and other ground and flight experiments. The book also aims to provide a tool for engineers, material scientists, and management in space and aerospace sectors to learn about the latest advances in the protection of materials and structures in LEO environment. It provides a basis for interaction and utilization of each others' capabilities in cross-pollenization of ideas. The text reviews research and development in topics such as: effects of LEO environment on materials and structures; predictive models for interaction of materials with LEO environment; and factors and alternative ways for protection from LEO environment.

Reducing the cost of the space programme interests people more and more, due to the concerns of budget limitation and commercialization of space technology. The Proceedings of the 3rd International Symposium on Reducing the Cost of Spacecraft Ground Systems and Operations bring together papers contributed by authors representing the research organizations, academic institutions and commercial sectors of ten countries around the world. The papers encompass the subject areas within mission planning and operation, TT&C systems, mission control centres, and small satellite support, highlighting the issues concerning researchers and engineers involved in a wide range of space programmes and space industries.

The IMCPSE-4 meeting continued the discussions started in 1992, when this conference series was started. The proceedings of IMCPSE-4 conference contain developments in the area of the effects of the space environment on materials and structures in the low Earth orbit and on ways to prevent and/or reduce them. The main mandate of the meeting, as in the past years was to: promote the dissemination of experimental data and experience among research organizations, and scientists gathered in ground and flight experiments; provide a tool for engineers, material scientists, and management in space and aerospace sectors to learn about advances in the field of material's and structures' protection in LEO environment and to provide a basis for interaction and utilization of each others' capabilities in cross pollenization of ideas; review the latest research and development in topics such as: effects of LEO environment on materials and structures, predictive models for interaction of materials with LEO environment factors, and alternative ways for protection from LEO environment.

This publication presents the proceedings of ICPMSE-6, the sixth international conference on Protection of Materials and Structures from Space Environment, held in Toronto May 1-3, 2002. The ICPMSE series of meetings became an important part of the LEO space community since it was started in 1991. Since then, the meeting has grown steadily, attracting a large number of engineers, researchers, managers, and scientists from industrial companies, scientific institutions and government agencies in Canada, U. S. A. , Asia, and Europe, thus becoming a true international event. This year’s meeting is gaining even stronger importance with the resumption of the ISS and other space projects in LEO, GEO and Deep Space. To reflect on these activities, the topics in the program have been extended to include protection of materials in GEO and Deep Space. The combination of a broad selection of technical and scientific topics addressed by internationally known speakers with the charm of Toronto and the hospitality of the organizers brings participants back year after year. The conference was hosted and organized by Integrity Testing Laboratory Inc. (ITL), and held at the University of Toronto’s Institute for Aerospace Studies (UTIAS). The meeting was sponsored by the Materials and Manufacturing Ontario (MMO) and the CRESTech, two Ontario Centres of Excellence; Air Force Office of Scientific Research (AFOSR/NL); MD Robotics; EMS Technologies; The Integrity Testing Laboratory (ITL); and the UTIAS.
