This description was generated automatically using input from the Planetary Data System.
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 relevant 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 ESA's Mars Express, SMART-1, Venus Express and Rosetta missions; NASA's Mars Global Surveyor, Stardust, Cassini, Mars Exploration Rovers, Mars Reconnaissance Orbiter and Deep Impact. The SPICE system has been produced and is maintained by Caltech's Jet Propulsion Laboratory under contract to the U.S. National Aeronautics and Space Administration.

NOTE: This data set incorporates all kernels from and fully supersedes the ROS-E/M/A/C-SPICE-6-V1.0 data set that was originally produced in 2007, released in 2010 and updated in 2011. The Rosetta SPICE data set consists of SPICE kernels of several types, organized as follows: * CK: These kernels contain information about orientation of the spacecraft and its articulating structures as well as orientation of the natural bodies that cannot be represented by standard IAU rotation models (e.g. the comet 67P/C-G). More information on CKs in this data set is provided in CKINFO.TXT. * DSK: These kernels contain information about the shape of the Rosetta mission targets. More information on DSKs in this data set is provided in DSKINFO.TXT. * FK: These kernels contain definitions of and specifications of relationships between reference frames (coordinate systems). Among the frames kernels included, there are kernels that specify reference frames related to the earth, mission targets, and the spacecraft and its instruments. More information on FKs in this data set is provided in FKINFO.TXT. * IK: These kernels contain instrument information, such as field of view or internal timing specifications. There are IKs provided for most of the Rosetta orbiter and lander instruments. More information on IKs in this data set is provided in IKINFO.TXT. * LSK: These kernels contain a table with the leapseconds used to convert between ET and UTC. If there are multiple LSKs in this data set, the latest kernel supersedes the previous ones. More information on LSKs in this data set is provided in LSKINFO.TXT. * PCK: These kernels provide information about the solar system bodies orientation and shape, and possibly parameters for gravitational, atmospheric or rings models. The data set contains PCKs for the planets, their satellites, the asteroids Lutetia and Steins, and the comet 67P/C-G. More information on PCKs in this data set is provided in PCKINFO.TXT. * SCLK: These kernels contain data needed for conversion between ET and spacecraft clock. If there are multiple SCLKs in this data set, the latest kernel supersedes the previous ones. More information on SCLKs in this data set is provided in SCLKINFO.TXT. * SPK: These kernels contain ephemeris data (position and velocity) of the spacecraft and solar system bodies. The data set provides kernels with such information for the planets, the Sun, the Moon, the comet 67P/C-G, the two fly-by asteroids Lutetia and Steins, the fly-by comet (Tempel 1), ground tracking stations, and the Rosetta orbiter and lander spacecraft. More information on SPKs in this data set is provided in SPKINFO.TXT. 3.1 - Origin of the kernels. a) Generic kernels such as PCKs, LSKs and some of the SPKs are provided by NAIF. b) IKs have been developed NAIF in collaboration with the instrument teams and RSSD/ESA. c) The majority of SPKs and CKs containing mission specific data for the spacecraft and for the mission targets as well as SCLKs were generated by RSSD/ESA from ancillary data files produced by ESOC. d) DSKs were generated by NAIF from other format shape model files produced by ESOC and by science instrument teams. 3.2 - Creation of SPK, CK and SCLK kernels from ESOC Ancillary Data. ESOC provided orbit and attitude data in the form of text files. These products were the source of the CK and SPK kernels. ESOC generated time correlation data records and stored them in the telemetry server. These records were the source for the SCLK kernel. An automated system, called ADCS (Automatic Data Conversion System) was responsible for the generation of CK, SPK and SCLK kernels from the ESOC flight dynamics data file products and telemetry server SCLK records. ADCS detected when a new product was generated or a new time correlation packet was available, and ran a series of processes in order to create the proper kernels. ADCS used the SPICE Toolkit in order to fulfill its task. It ran on a server physically located at ESTEC until December 2007; after that date, the server was located at ESAC. 3.3 - Using the SPICE kernels. At least a basic knowledge of the SPICE system is needed in order to use these kernels. The SPICE Toolkit provides versions in Fortran (SPICELIB), C (CSPICE), IDL (icy), Matlab (Mice), and Java (JNISpice) and the user can choose any one that suits him/her. The SPICE routine FURNSH can be used to load a kernel file into a SPICE-based application to make kernel's data usable with SPICE APIs. In the case when two or more kernel files contain data overlapping in time for a given object, for binary kernels, the file loaded last takes precedence. If two (or more) text kernels assign value(s) using the '=' operator to identical keywords, the data value(s) associated with the last loaded occurrence of the keyword are used -all earlier values have been replaced with the last loaded value(s). 3.4 - Meta-kernels The easiest way to make data from a collection of SPICE kernels available to a SPICE-based application is to list these kernels in a meta-kernel and load it into the program using the high level SPICE data loader routine FURNSH. This data set provides such meta-kernel(s) under the EXTRAS/MK directory. For more information about the Rosetta meta-kernels, see the file EXTRAS/MK/MKINFO.TXT.
