PVO Spacecraft VSO Ephemeris and Spacecraft Orientation Original Binary Data Collection
Listed in IVOA Registry (Virtual Observatory)
This collection includes Pioneer Venus Orbiter (PVO) ephemeris, spacecraft position and orientation data in Venus Solar Orbital (VSO) coordinates.
Description
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).
