The Aerospace Corporation is a California nonprofit corporation that operates a Federally Funded Research and Development Center (FFRDC) headquartered in El Segundo, California. The corporation provides technical guidance and advice on all aspects of space missions to military, civil, and commercial customers to assure space mission success.〔 〕 As the FFRDC for national-security space, Aerospace works closely with organizations such as the United States Air Force Space and Missile Systems Center (SMC) and the National Reconnaissance Office (NRO) to provide "objective technical analyses and assessments for space programs that serve the national interest". Although SMC and NRO are the primary customers, Aerospace also performs work for civil agencies as well as international organizations and governments in the national interest.〔 〕 ==History== On July 1, 1954, the Western Development Division (WDD) of the United States Air Force was established, under the command of Brig. Gen. Bernard A. Schriever. WDD was responsible for the development of the ICBM. The Ramo-Wooldridge Corporation (RW) was identified as the civilian organization responsible for systems engineering for the ICBM program. Their Space Technology Laboratories (STL) was responsible for all missile tasks. Despite early successes, there was criticism from both government and industry on the role RW played as systems engineer, in particular that RW held a privileged position with the Air Force. In 1958 RW merged with Thompson Products to became TRW and the Space Technology Laboratories became an independent subsidiary of TRW, but concerns regarding conflicts of interest persisted. In September 1959, United States Congress issued ''House Report 1121'' which recommended that STL be converted into a non-profit institution.〔"The Aerospace Corporation, Its Work 1960-1980", pages 12-17. Library of Congress Catalogue Card No. 80-67774〕 Congress wanted the establishment of an organization, free from conflict of interest, to aid the Air Force in "applying the full resources of modern science and technology to the problem of achieving those continuing advances in ballistic missiles and military space systems."〔(【引用サイトリンク】url=http://www.aero.org/corporation/historytimeline.html )〕 On June 4, 1960 Aerospace was established under the laws of the State of California as a nonprofit corporation.〔Davis Dyer, ''TRW: Pioneering Technology and Innovation Since 1900'' (Harvard Business School Press, 1998), p231〕 On June 25, 1960, at a press conference held at the U.S. Air Force Ballistic Missile Division headquarters in El Segundo, California, Lt. Gen. Bernard A. Schriever announced the "formation of a new nonprofit organization, The Aerospace Corporation, to serve the Air Force in the scientific and technical planning and management of missile-space programs."〔(【引用サイトリンク】url=http://www.aero.org/programs/ )〕 Among the earliest projects it supported were the Dyna-Soar orbital spaceplane, Project Mercury, and the man-rating of the Atlas (rocket) intercontinental ballistic missile. The Aerospace Corporation provided general systems engineering and technical direction for the Titan II missile, first tested in 1962, which became the launch vehicle for Project Gemini. Other notable projects of the 1960s include the advanced ballistic re-entry system (ABRES), the Air Force's Manned Orbiting Laboratory (MOL), the Defense Satellite Communications System (DSCS), and the Defense Support Program (DSP). During the 1970s, Aerospace began performing advance space program analysis and program studies for NASA's development of the Space Transportation System (STS), more commonly known as the space shuttle. Aerospace also began tests on airborne UHF terminals for the Air Force Satellite Communications System, AFSATCOM. In the mid-70s Aerospace assumed general systems engineering and integration responsibility for the Defense Meteorological Satellite Program (DMSP). Beginning in 1973, a program office was established to assist the Air Force in the creation of the Global Positioning System (GPS). In recognition of their GPS collaboration, Aerospace shared the 1992 Robert J. Collier Trophy, the nation's highest award for aeronautical achievement, "for the most significant development for safe and efficient navigation and surveillance of air and spacecraft since the introduction of radio navigation 50 years ago." 〔(【引用サイトリンク】url=http://www.nrl.navy.mil/content.php?P=COLLIER )〕 Throughout the 1980s, Aerospace supported the Inertial Upper Stage (IUS), the Strategic Defense Initiative (SDI), the Milstar and DSCS satellite communication systems, and antisatellite (ASAT) programs. They provided planning, design, and evaluation for the Air Force Satellite Control Network (AFSCN) and the Consolidated Space Operations Center at Schriever Air Force Base in Colorado. During this same time period, the company also provided systems engineering and integration for launch vehicles, including the Atlas, Titan II, Titan IV, and Delta II. In the 1990s, Aerospace participated in the planning and development of system requirements for the Evolved Expendable Launch Vehicle (EELV) program, the next generation of launch vehicles. They continued to provide launch vehicle systems engineering for the Atlas II, Delta III, and Titan IVB. Satellite program support included Wideband Gapfiller, Space Based Laser, the Ultrahigh-Frequency Follow-On program, and the Global Broadcast Service. Throughout the second half of the 90s, the corporation conducted independent assessments for the International Space Station, provided technical support for the Cassini spacecraft, and supported the acquisition of the Space-Based Infrared System (SBIRS) satellite constellation. Most recently, The Aerospace Corporation provided further technical assistance to EELV programs including the Atlas V and Delta IV, and supported planning for Space Radar to provide global persistent intelligence, surveillance, and reconnaissance to the Department of Defense. Aerospace has been involved in the analysis of concept designs for the Space Tracking and Surveillance System (SSTS). Aerospace plays an integral role in the development of the Advanced Extremely High Frequency (AEHF) program that will replace the Milstar system. Another system that Aerospace was supporting is the Transformational Satellite Communications System MILSATCOM architecture to link military and reconnaissance communication networks. However, it was cancelled per the recommendations of Defense Secretary Robert M. Gates due to DoD budgetary constraints.〔http://www.defense.gov/speeches/speech.aspx?speechid=1341〕 Aerospace remains a significant partner in the continuing evolution of the GPS system. Aerospace has been playing a leading role in the planning and acquisition of Geostationary Operational Environmental Satellite for the National Oceanic and Atmospheric Administration. In 2005, Aerospace supported the Air Force Affordable Responsive Spacelift (ARES) launch system demonstration program.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「The Aerospace Corporation」の詳細全文を読む スポンサード リンク
