VEX-E-V-SPICE-6

1. SPICE System Overview SPICE data contain geometric and other ancillary information needed to recover the full value of science instrument data. In particular, SPICE kernels provide spacecraft and planetary ephemerides, instrument mounting alignments and spacecraft orientation. Data needed for r^ant time conversions is also included. SPICE was designed by the Navigation and Ancillary Information Facility (NAIF) to aid scientists and engineers with ancillary and engineering data. This data comes from a wide range of sources such as the spacecraft, the mission control center and the designers of the spacecraft and its instruments. The ancillary data comprises information on data acquisition; position and orientation of the spacecraft at the time of acquisition; information on the target, such as location, shape and orientation; reference frame specifications and time conversion data. The primary SPICE data sets are often called kernels or kernel files. These kernels are composed of ancillary information, which has been created in such a way as to allow easy access and correct usage by the space science and engineering communities. In addition to the kernels, there is software provided, known as the SPICE Toolkit, along with standards, documentation and software support. The SPICE Toolkit and documentation can be found at: http://naif.jpl.nasa.gov/naif/ The SPICE Toolkit was freely offered to the worldwide space science and space mission engineering communities at the time this data set was released. The few rules governing its use are posted on the Rules page of the NAIF website: http://naif.jpl.nasa.gov/naif/rules.html SPICE is used on a number of space missions, such as ESAs Mars Express, SMART1, Venus Express, ExoMars2016, BepiColombo, Solar Orbiter and Rosetta missions, and all of NASAs solar system exploration missions. The SPICE system has been produced and is maintained by Caltechs Jet P truncated!, Please se [truncated!, Please see actual data for full text]
