FOREWORD This proceedings volume, which consists of one hard cover bound volume and a CD ROM supplement (also available in digital format), includes the available papers presented at the Fifteenth International Space Conference of Pacific-basin Societies (ISCOPS), July 10-13, 2018, Montréal, Québec, Canada. This sequence of ISCOPS volumes is usually pub- lished as a part of the AAS Advances in the Astronautical Sciences series. Earlier ISCOPS proceedings volumes are available through the American Astronautical Society as follows: (1) The first symposium was held December 15-19, 1985 in Honolulu, Hawaii and was published as Volume 60, Advances in the Astronautical Sciences titled Space Exploitation and Utilization. (2) The second symposium was held June 7-10, 1987 in Beijing, China. This publication was published in China and titled Proceedings of the Pacific Basin International Symposium of Advances in Space Science Technology and its Applications (PISSTA). (3) The third symposium was held November 6-8, 1989 in Los Angeles, California and was published as Volume 73, Advances in the Astronautical Sciences titled Space Utilization and Applications in the Pacific. (4) The fourth symposium was held November 17-20, 1991, Kyoto, Japan and was published as Volume 77, Advances in the Astronautical Sciences titled International Space Year (ISY) in the Pacific Basin. (5) The fifth symposium was held June 6-9, 1993, Shanghai, China. This volume was published in China (not available through the AAS). (6) The sixth symposium was held December 6-8, 1995, Marina Del Rey, California, U.S.A. and was published as Volume 91, Advances in the Astronautical Sciences titled Strengthening Cooperation in the 21st Century. (7) The Seventh symposium was held July 15-18, 1997, Nagasaki, Japan, and was published as Volume 96, Advances in the Astronautical Sciences titled Space Cooperation into the 21st Century. (8) The eighth symposium was held June 23-26, 1999, Xian, China. This volume was published in China (not available through AAS). (9) The ninth symposium was held November 14-16, 2001, Pasadena, California, U.S.A. and was published as Volume 110, Advances in the Astronautical Sciences titled Space Development and Cooperation Among All Pacific Basin Countries. (10) The tenth symposium was held December 10-12, 2003, Tokyo, Japan, and was published as Volume 117, Advances in the Astronautical Sciences titled Space Activities and Cooperation Contributing to All Pacific Basin Countries. (11) The eleventh symposium was held May 16-18, 2007, Beijing, China (not available through AAS). (12) The twelfth symposium was held July 27-30, 2010, Montréal, Québec, Canada, and was published as Volume 138, Advances in the Astronautical Sciences titled Applications of Space Technology for Humanity. (13) The thirteenth symposium was held May 15-18, 2012, Kyoto, Japan, and was published as Volume 146, Advances in the Astronautical Sciences titled Space for Our Future. (14) The fourteenth symposium was held May 28-30, 2014, Xi’an, China (not available through AAS). Several other sequences or subseries have been established in the Advances in the Astronautical Sciences series. Among them are: Astrodynamics, Spaceflight Mechanics, Guidance, Navigation and Control, and various other AAS-sponsored or co-sponsored con- ferences. Proceedings volumes for earlier conferences are still available either in hard copy or in microfiche form, and more recent volumes are available in digital format. The appen- dix at the end of this volume lists proceedings available through the American Astronautical Society. In proceedings volumes of the American Astronautical Society the technical accuracy and editorial quality are essentially the responsibility of the authors because the papers are essentially composed of camera-ready copy provided by the authors. The reader should bear in mind that for an international conference, such as the Fifteenth ISCOPS, many papers were prepared by authors whose native language is not English. The session chairs and our editors do not review all papers in detail; however, format and layout are improved when necessary by our editors. In some cases the English is improved so it reads better. For this conference, the many authors whose native language is not English are to be congratulated on the quality of material submitted and are to be thanked for their significant contributions to this English-language volume. The editors wish to express their thanks to all those who have contributed to the success of this conference and to authors for their efforts in finaliz- ing material for publication. Robert H. Jacobs Series Editor Advances in the Astronautical Sciences PREFACE The Fifteenth International Space Conference of Pacific-basin Societies (15th ISCOPS), under the theme “Promote the Progress of the Pacific-basin Region through Space Innovation” was held at McGill University, Montreal, Canada from July 10 to July 13, 2018. This conference was the fifteenth in a continuing series of biennial conferences co-sponsored by the American Astronautical Society (AAS), the Chinese Society of Astro- nautics (CSA), and the Japanese Rocket Society (JRS). The final program of the conference consisted of 62 presentations in total, including the Plenary Lectures as well as papers presented in nine Technical Sessions and in two In- ternational Student Competition Sessions. This volume of Proceedings includes most of the papers presented in the technical and student competition sessions. The topics covered in the nine technical sessions were Astrodynamics, Guidance and Control (2 sessions), Launch Ve- hicles, Space Exploration and Space Robotics, Space Power and Propulsion, Small Satel- lites, Formation Flying and Constellations, Space Materials and Structures, Space Systems and Infrastructure, as well as Space Debris. The organizing committee of the 15th ISCOPS gratefully acknowledges the financial and logistical support provided by the McGill Institute for Aerospace Engineering (MIAE). The organizers are also grateful to the Canadian Space Agency and Dr. Alfred Ng for ar- ranging an excellent technical tour. We greatly appreciate the patience and painstaking effort of Mr. Robert H. Jacobs, the AAS Series Editor, in producing these Proceedings. We would also like to thank all the au- thors, session chairs and conference attendees who made the 15th ISCOPS a success. The 16th ISCOPS will be hosted by the Japanese Rocket Society (JRS) in Japan and is planned for 2020. We look forward to working together again to ensure the continued suc- cess of the ISCOPS series.
