The GEOMETRY directory contains ephemerides and files describing
the pointing of the Voyager 1 High-Gain Antenna (HGA) during the radio
occultations at Titan.
Each file is accompanied by a detached PDS label. Each label is an
ASCII file with 80 character records. Records are delimited by the ASCII
carriage-return (ASCII 13) line-feed (ASCII 10) pair at the end of each
line (positions 79 and 80).
The files are:
GEOMINFO.TXT
This file, which gives a brief summary of the directory contents.
CRS009AA.CRS
An ASCII file containing four PDS TABLE objects. Three tables contain
header information; the fourth is a set of state vectors for Voyager 1 and
relevant solar system bodies (Sun, Earth, Saturn, Titan) during the
Voyager 1 encounter with Titan. This file has been converted from the
Univac binary original, distributed on tape by the Voyager Project under the
name CRS009. The accompanying PDS label (file CRS009AA.LBL) describes the
detailed format and contents of the file.
VG1_SAT.SPK
An ASCII file containing the current SPK file (ephemerides) in NAIF
transfer format for the Voyager 1 encounter with Saturn. Individual lines
in the file are delimited by ASCII carriage-return line feed pairs, which
may need to be converted to the local default line delimiter before the
file can be used. The file is accompanied by a PDS minimal label; the
label points to TK_FTP.TXT in the DOCUMENT directory for more information
on format, content, and reader software.
VH009.DAT
A binary file describing pointing of the Voyager 1 High-Gain Antenna
(HGA) during the Titan encounter. The file is accompanied by a minimal
PDS label (filename VH009.LBL) which briefly describes its contents. See
VH009T.TAB for an ASCII version of the same file.
VH009T.TAB
An ASCII file containing HGA pointing information for the Voyager 1
spacecraft during the Titan encounter. The file is a conversion of the
binary data contained in VH009.DAT. PDS label VH009T.LBL describes both
the format and content of the ASCII file.
