The Deep Space 1 SPICE Data Archive
========================================================================
Introduction
============
This document provides an overview of this volume of the Deep Space 1
SPICE Data Archive, including a description of the volume structure.
Additional documents included on this volume provide more details,
especially the "spiceds.cat" dataset description and the various
kernel-specific "/data/*/*info.txt" files.
This volume contains navigation and related observation geometry and
other ancillary data in the form of SPICE System kernel files for
the Deep Space 1 spacecraft. See the file "mission.cat" in the
"/catalog" directory for a description of the Deep Space 1 mission
and the file "insthost.cat" in the same directory for a
description of the spacecraft.
The SPICE kernel files contain geometric and other ancillary
information needed to recover the full value of science instrument
data. Data in the SPICE kernel files must be accessed using the NAIF
(Navigation and Ancillary Information Facility) software called the
SPICE Toolkit. See the file "softinfo.txt" in the "/software"
directory for instructions on how to obtain this software.
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 MacOS 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 the IEEE standard. While some of the data files on
this volume can be used 'as is', converting the files to binary or
text format native to the user's computer may be required. Refer to
the documentation provided with the SPICE Toolkit to find out
whether conversion is needed in each specific case.
NAIF provides a tool that can convert either binary or text kernels
from one format to another. This means that text files can have
their line terminator changed and binary files can be converted to
the native format of the platform of interest. For access to this
tool, see the reference to the NAIF utilities website in the file
"/software/softinfo.txt".
