    Introduction
    ============

       This document describes the ExoMarsRSP SPICE kernel dataset (SKD)
       containing observation geometry and other ancillary data in the form of
       SPICE System kernel files for the TGO spacecraft, the EDM lander and its
       instruments and targets. It describes the dataset directory structure,
       kernels included in the dataset, their naming conventions, and provides
       pointers to the SPICE software and documentation.

    Overview
    ========

       This archive includes the complete set of ExoMarsRSP SPICE data files
       (kernel files), which can be accessed using SPICE software. The
       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,
       spacecraft and instrument orientation, instrument mounting
       alignments, and data needed for relevant time conversions. Data in
       the SPICE kernel files must be accessed using the software called
       the SPICE Toolkit produced and distributed by the Navigation and
       Ancillary Information Facility (NAIF) Node of the Planetary Data
       System.

       This archive includes data covering from ExoMarsRSP launch, 2016-03-14,
       through the end time of the latest spacecraft orientation file
       supplied in the archive. Until the end of the spacecraft lifespan
       this archive will be accumulating with new data added according to
       the project archiving plan.

    Kernel Types
    ============

       Different SPICE kernel types are used to store different kinds of
       ancillary data.

       SPK (Spacecraft Planet Kernel) files contain ephemerides (position
       and velocity) for spacecraft, planets, satellites, comets and
       asteroids as well as for moving or fixed spacecraft and instrument
       structures. SPK files are located under the kernels/spk
       directory of this archive.

       PCK (Planetary Constants Kernel) files contain certain physical,
       dynamical and cartographic constants for target bodies, such as size
       and shape specifications, and orientation of the spin axis and prime
       meridian. PCK files are located under the kernels/pck
       directory of this archive.

       IK (Instrument Kernel) files contain instrument parameters relevant
       for computing an instrument's geometry such as field-of-view
       definitions, CCD and optical distortion characteristics, and internal
       timing parameters. IK files are located under the kernels/ik
       directory of this archive.

       CK (C-matrix Kernel) files contain time varying orientations for
       spacecraft, spacecraft structures, and articulating science
       instruments. CK files are located under the kernels/ck
       directory of this archive.

       LSK (Leapseconds Kernel) files contain the leapseconds and the
       values of other constants required to perform a transformation
       between Universal Time Coordinated (UTC) and Ephemeris time (ET),
       which is also known as Barycentric Dynamical Time (TDB). LSK
       files are located under the kernels/lsk directory of
       this archive.

       SCLK (Spacecraft Clock Kernel) files contain on-board clock
       calibration data required to perform a transformation between
       Ephemeris time (ET) and spacecraft on-board time (SCLK). SCLK files
       are located under the kernels/sclk directory of this
       archive.

       FK (Frame definitions Kernel) files contain information required to
       define reference frames, sources of frame orientation data and
       connections between these frames and other frames supported within
       the SPICE system. The science instrument frame definitions provided
       in the FK files include mounting alignment information for the
       instruments. FK files are located under the kernels/fk
       directory of this archive.

       MK (Meta-Kernel) files list sets of related SPICE kernels that
       should be used together, providing an easy way to make data from
       these kernel sets available to a SPICE-based application by loading
       meta-kernels into the program using the high level SPICE data loader
       routine FURNSH. MK files are located the kernels/mk
       directory of this archive.
