29、AP prediction error in days . 72 ANSI/AIAA S-131-2010 vii Foreword One of the most significant scientific and technological accomplishments since the beginning of the space era is the successful deployment of space systems and the necessarily ingenious application of astrodynamics to support these s

30、ystems. Astrodynamics has been developed by extending the knowledge accumulated since the first recorded investigations into the motions of heavenly bodies. The outgrowth of civilian and military rocket system developments has led to the establishment and implementation of numerous space systems, re

31、lated physical models, and astrodynamics theories, algorithms, and procedures. With the proliferation of different and independent space systems and advancements in technology and astrodynamic sciences, the interfacing needed to ensure interoperability within space operations has become more complex

32、. The ASD/CoS charter is to “Identify, establish, and publish astrodynamics standards, guides, and recommended practices to ensure the continued enhancement of aerospace-wide efficiency and productivity to meet the scientific, technological and operational demands.” To accomplish the chartered goals

33、, the strategy is to: Research and establish the up-to-date status of the astrodynamics standards and practices currently available. Identify scientific, technological, and operational programs and system elements that have a need for astrodynamics standards and consensus practices. Perform in-depth

34、 analyses of the existing standards and practices and develop recommendations for possible adoption and/or modifications as AIAA standards or practices. Develop definition of standards and adopt formal guidelines and requirements of standardization. Recommend and propose the areas where new standard

35、s, guides, and recommended practices are required. Additionally, identify areas where standards are currently not appropriate. Identify, develop, and document candidate new astrodynamics standards, guides, and recommended practices for consideration. Perform independent verification and validation,

36、including solicitation of in-depth reviews within industry, academia, and government laboratories for all proposed and documented standards, guides, and recommended practices. Submit proposed standards, guides, and recommended practices to the Standards Executive Council for approval and publication

37、. Maintain all relevant technical materials and standards. Maintain technical coordination with scientific and astrodynamics communities nationally and internationally. To help provide coherent direction for its activities in identifying and selecting topics, the committee approved a set of criteria

38、. Fundamentally, the committee has taken the view that the objective of an astrodynamic standard is to provide guidance on practices that will ensure and enhance interoperability between organizations. Following are the criteria that have been useful in selecting topics that achieve this objective:

39、Scope: Does the topic relate to processes associated with describing the motion of orbiting bodies? Although rather evident, the committee has occasionally found itself considering topics that really fall within the purview of a different area or responsibility. ANSI/AIAA S-131-2010 viii Utility: Is

40、 the topic of wide concern to the majority of the astrodynamics community, and does it deal with the process of information exchange among members of that community? If a topic is of only minor relevance to the community, developing standards may not be particularly useful. Thus, such standards shou

41、ld aim at facilitating the broadest information exchange across the community. Alternatives (Ambiguity): Does the topic involve alternative ways of performing a process or accomplishing an objective? In cases where multiple alternatives exist, we tried to give guidance on the variability of applicat

42、ions, indicating what the community consensus is. Where only one commonly accepted alternative existed, we determined if there was any potential confusion in its application. Practicality: Can agreement be achieved on standardization? Despite meeting all the above criteria, insufficient consensus ma

43、y demand not treating the topic. The ASD/CoS initial effort, Recommended Practice, AstrodynamicsPart I, was chaired by Dr. Joseph J. F. Liu. A Part II document was initiated by Dr. Hamilton Hagar, but was never officially finished in its original form. The current document supersedes the Part I and

44、Part II and forms a unified document, including specific treatment of standards and recommended practices. The current version focuses on propagation for Earth orbiting satellites. At the time of approval, the members of the AIAA Astrodynamics Committee on Standards were: David A. Vallado, Chair Cen
