The New Horizons
SPICE Data Archive
========================================================================
Introduction
============
This document provides an overview of this
volume of the New Horizons
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 New Horizons spacecraft. See the file
"mission.cat" in the "/catalog"
directory for a description of the New
Horizons mission and the file
"insthost.cat" same directory for
a description of the two 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. 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". In
addition, the SPICE Toolkit contains a
command line program that will convert
binary files.
