NAME |
PVO Spacecraft VSO Ephemeris and Spacecraft Orientation Original Binary Data Collection
|
TYPE |
Data
|
DESCRIPTION |
This collection includes Pioneer Venus Orbiter (PVO) ephemeris, spacecraft position and
orientation data in Venus Solar Orbital (VSO) coordinates. This collection is
sampled every 12 seconds near periapsis, and at 1 minute or 10 minute rates
in the solar wind, the lowest rates near apoapsis. Planetocentric and
heliocentric position vectors and solar zenith angle (Sun-Venus-PVO) are
also provided. The VSO parameters are derived from the PVO Supplemental
Experimenter Data Records (SEDR), other parameters are taken
directly from the SEDR dataset.
The original data files submitted to the PDS are IGPP flatfiles. An IGPP
flatfile is a collection of 2 files, each of which could be considered
a table. The data file (.FFD) is a binary table of data values. The header
file (.FFH) is an ASCII table which describes the data file (.FFD) and is
used by the UCLA/IGPP Data Flow System (a software package).
