NAME |
PVO Spacecraft VSO Ephemeris and Spacecraft Orientation ASCII 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 were all binary and contained a non-standard time
representation. No software was provided to convert these data to ASCII.
PDS created ASCII versions of these files in response to user concerns
regarding the ease of use of these data.
