SPICE is a NASA ancillary information system used to compute geometric information used in planning and analyzing science observations obtained from robotic spacecraft. It is also used in planning missions and conducting numerous engineering functions needed to carry out those missions.〔(【引用サイトリンク】 The SPICE Concept )〕 SPICE was developed at NASA's Navigation and Ancillary Information Facility (NAIF), located at the Jet Propulsion Laboratory.〔(【引用サイトリンク】 About NAIF )〕 It has become the de facto standard for handling much of the so-called observation geometry information on NASA's planetary missions, and it is now widely used in support of science data analysis on planetary missions of other space agencies as well. Some SPICE capabilities are used on a variety of astrophysics and solar physics missions. SPICE consists of both data and software. == Data == SPICE data files are usually referred to as "kernels." These files provide information such as spacecraft trajectory and orientation; target body ephemeris, size and shape; instrument field-of-view size, shape and orientation; specifications for reference frames; and tabulations of time system conversion coefficients.〔(【引用サイトリンク】 Components )〕 SPICE data are archived in a national archive center such as the NASA Planetary Data System archives.〔(【引用サイトリンク】 Archived Data )〕 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「Spacecraft Planet Instrument C-matrix Events」の詳細全文を読む スポンサード リンク
