The Mars Odyssey SPICE Data Archive
========================================================================
Introduction
============
This document provides an overview of this volume of the Mars
Odyssey SPICE Data Archive, including a complete listing
of the volume contents.
This volume contains navigation and ancillary data in the form of
SPICE System kernel files for the Mars Odyssey (ODY)
spacecraft. See the file mission.cat in the catalog
directory for a description of the various phases of the mission.
The SPICE kernel files contain geometric and much 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, spacecraft orientation,
spacecraft sequences of events, data needed for certain time
conversions, etc. Data in the SPICE kernel files can be accessed
using the NAIF (Navigation and Ancillary Information Facility)
software necessary to read these files.
File Formats
============
All text documents and other meta information files such as
descriptions, PDS object definitions and detached PDS labels are
stream format files, with a carriage return (ASCII 13) and a line
feed character (ASCII 10) at the end of the record. This allows
the files to be read by MS-DOS/Windows, Unix, and VMS operating
systems.
The data files on this version of the disk were prepared to be used
under a UNIX environment. Therefore all SPICE text kernel files are
UNIX text files, with a line feed character (ASCII 10) at the end
of the line, and all SPICE binary kernels files are UNIX binary
files in which bit pattern structures for double precision and
integer numbers follow IEEE standard.
Volume Contents
