System Analysis and Design of the Geostationary Earth Orbit All-Electric Communication Satellites
https://doi.org/10.1590/jatm.v13.1205 REVIEW ARTICLE System Analysis and Design of the Geostationary Earth Orbit All-Electric Communication Satellites Parsa Abbasrezaee1,* , Ali Saraaeb2 1.Sapienza University of Rome – Aerospace Engineering School – Rome – Italy. 2.Khaje Nasir Toosi University of Technology – Aerospace department – Tehran – Iran. *Corresponding author: [email protected] ABSTRACT With the help of gathered data and formulas extracted from a previous conference paper, the all-electric geostationary Earth orbit (GEO) communication satellite statistical design was conducted and further studied with analytic hierarchy process (AHP) and technique for order of preference by similarity to ideal solution (TOPSIS) methods. Moreover, with the help of previously determined system parameters, the orbital ascension, orbital maintenance and deorbiting specifications, calculations and simulations were persuaded. Furthermore, a parametric subsystem design was conducted to test the methods reliability and prove the feasibility of such approach. The parametric subsystem design was used for electrical power subsystem (EPS), attitude determination and control system (ADCS), electric propulsion, telemetry, tracking and control (TT&C) in conceptual subsystem design level, which highly relies on the satellite type and other specifications, were concluded in this paper; other subsystem designs were not of a significant difference to hybrid and chemical satellites. Eventually, the verification of the mentioned subsystems has been evaluated by contrasting the results with the Space mission engineering: the new SMAD, and subsystem design book reference. Keywords: All-electric; GEO; AHP and TOPSIS Method; Maintenance; Deorbiting; Parametric. INTRODUCTION From the previous conference paper, the contrast between all-electric geostationary Earth orbit (GEO) communication and other hybrid and chemical satellite design has shown that using all-electric satellite design has many advantages. -

Classification of Geosynchronous Objects
esoc European Space Operations Centre Robert-Bosch-Strasse 5 D-64293 Darmstadt Germany T +49 (0)6151 900 www.esa.int CLASSIFICATION OF GEOSYNCHRONOUS OBJECTS Produced with the DISCOS Database Prepared by T. Flohrer & S. Frey Reference GEN-DB-LOG-00195-OPS-GR Issue 18 Revision 0 Date of Issue 3 June 2016 Status ISSUED Document Type TN European Space Agency Agence spatiale europeenne´ Abstract This is a status report on geosynchronous objects as of 1 January 2016. Based on orbital data in ESA’s DISCOS database and on orbital data provided by KIAM the situation near the geostationary ring is analysed. From 1434 objects for which orbital data are available (of which 2 are outdated, i.e. the last available state dates back to 180 or more days before the reference date), 471 are actively controlled, 747 are drifting above, below or through GEO, 190 are in a libration orbit and 15 are in a highly inclined orbit. For 11 objects the status could not be determined. Furthermore, there are 50 uncontrolled objects without orbital data (of which 44 have not been cata- logued). Thus the total number of known objects in the geostationary region is 1484. In issue 18 the previously used definition of ”near the geostationary ring” has been slightly adapted.

Suborbital Reusable Launch Vehicles and Applicable Markets
SUBORBITAL REUSABLE LAUNCH VEHICLES AND APPLICABLE MARKETS Prepared by J. C. MARTIN and G. W. LAW Space Launch Support Division Space Launch Operations October 2002 Space Systems Group THE AEROSPACE CORPORATION El Segundo, CA 90245-4691 Prepared for U. S. DEPARTMENT OF COMMERCE OFFICE OF SPACE COMMERCIALIZATION Herbert C. Hoover Building 14th and Constitution Ave., NW Washington, DC 20230 (202) 482-6125, 482-5913 Contract No. SB1359-01-Z-0020 PUBLIC RELEASE IS AUTHORIZED Preface This report has been prepared by The Aerospace Corporation for the Department of Commerce, Office of Space Commercialization, under contract #SB1359-01-Z-0020. The objective of this report is to characterize suborbital reusable launch vehicle (RLV) concepts currently in development, and define the military, civil, and commercial missions and markets that could capitalize on their capabilities. The structure of the report includes a brief background on orbital vs. suborbital trajectories, as well as an overview of expendable and reusable launch vehicles. Current and emerging market opportunities for suborbital RLVs are identified and discussed. Finally, the report presents the technical aspects and program characteristics of selected U.S. and international suborbital RLVs in development. The appendix at the end of this report provides further detail on each of the suborbital vehicles, as well as the management biographies for each of the companies. The integration of suborbital RLVs with existing airports and/or spaceports, though an important factor that needs to be evaluated, was not the focus of this effort. However, it should be noted that the RLV concepts discussed in this report are being designed to minimize unique facility requirements. -

Tel: +61 7 389 63754 Email: [email protected] 1 GNSS Satellite-Based Augmentation Systems for Australia ABSTRACT This paper provides an overview of various Satellite-Based Augmentation Systems (SBAS) options for augmented GNSS services in Australia, and potentially New Zealand, with the aim to tease out key similarities and differences in their augmentation capabilities. SBAS systems can technically be classified into two user categories, namely SBAS for aviation and “non-aviation” SBAS. Aviation SBAS is an International Civil Aviation Organisation (ICAO) certified civil aviation safety critical system providing wide-area GNSS augmentation by broadcasting augmentation information using geostationary satellites. The primary aim is to improve integrity, availability and accuracy of basic GNSS signals for aircraft navigation. -

EVA Physiology & Medical Considerations Working in the Suit
JSC/EC5 U.S. Spacesuit Knowledge Capture (KC) Series Synopsis Topic: EVA Physiology & Medical Considerations Working in the Suit Date: January 24, 2012 Location: Johnson Space Center (JSC), Houston, TX Presenter: Scott Parazynski, M.D. Synopsis: This “EVA Physiology & Medical Considerations Working in the Suit” presentation covers several topics related to the medical implications and physiological effects of suited operations in space from the perspective of a physician with considerable first-hand Extravehicular Activity (EVA) experience. Key themes include EVA physiology – working in a pressure suit in the vacuum of space, basic EVA life support and work support, Thermal Protection System (TPS) inspections and repairs, and discussions of the physical challenges of an EVA. Parazynski covers the common injuries and significant risks during EVAs, as well as physical training required to prepare for EVAs. He also shares overall suit physiological and medical knowledge with the next generation of Extravehicular Mobility Unit (EMU) system designers. Biography: Dr. Scott Parazynski is a physician and a physiologist with expertise in human adaptation to stressful environments, having been graduated from Stanford University and Stanford Medical School. He went on to train at Harvard University and in Denver in preparation for a career in emergency medicine and trauma. In 1992 he was selected to join NASA’s Astronaut Corps and eventually flew five Space Shuttle missions and conducted seven spacewalks (EVAs). In October 2007, Parazynski led the EVA team on STS-120, a highly complex space station assembly flight, during which he performed four EVAs. The fourth and final EVA is regarded by many as one of the most challenging and dangerous ever performed. -
