MESSENGER MAG Time-Averaged Calibrated VSO Coordinates Science Data
Collection
Short Name:
mess_mag_calibra
Date:
25 Apr 2025 02:02:09
Publisher:
Planetary Data System
Description:
Time-averaged spacecraft position and calibrated 3-axis magnetic
field samples in Venus Solar Orbital (VSO) coordinates. The data are
tagged with latency corrected UTC and MET time stamps at the center of
each interval. The VSO RDR is derived from the Science CDR for this
coordinate system with time averages computed within 1, 5, 10, and 60
s intervals.
MESSENGER Radio Science Delta Differential One-way Ranging (DDOR) Data
Products Collection
Short Name:
mess_rs_raw_ddor
Date:
25 Apr 2025 01:58:59
Publisher:
Planetary Data System
Description:
DDOR files were generated in the TNF (TRK-2-34) format and contain
only TNF data type 10 records. The TNF collection in the MESSENGER
archive does not contain data type 10 records.
MESSENGER Radio Science Orbit Data File (ODF) Product Collection
Short Name:
mess_rs_raw_odf.
Date:
25 Apr 2025 02:01:10
Publisher:
Planetary Data System
Description:
This is the collection of Radio Science Orbit Data File (ODF) data
products acquired during the MESSENGER mission. These ODF files were
produced by the NASA/JPL Multi-Mission Navigation Radio Metric Data
Conditioning Team for use in determining spacecraft trajectories,
gravity fields affecting them, and radio propagation conditions.
MESSENGER Radio Science RSR Data Products Collection
Short Name:
mess_rs_raw_rsr.
Date:
25 Apr 2025 02:08:09
Publisher:
Planetary Data System
Description:
This is the collection of Radio Science Receiver (RSR) data products
acquired during the MESSENGER mission. RSR is a computer-controlled
open loop receiver that digitally records a spacecraft signal through
the use of analog to digital converters (ADCs) and up to four digital
filter sub-channels.
MESSENGER Radio Science Tracking and Navigation (TNF) Data Products
Collection
Short Name:
mess_rs_raw_tnf.
Date:
25 Apr 2025 01:58:35
Publisher:
Planetary Data System
Description:
This is the collection of Radio Science Tracking and Navigation (TNF)
data products acquired during the MESSENGER mission. Data were
originally stored as chronological records in DSN format TRK-2-34; but
they have been sorted according to data type (retaining chronological
order within each data type) during migration from PDS3 to PDS4.
PVO Spacecraft VSO Ephemeris and Spacecraft Orientation ASCII Data
Collection
Short Name:
pvo_ephem_vso_as
Date:
25 Apr 2025 02:03:37
Publisher:
Planetary Data System
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.
PVO Spacecraft VSO Ephemeris and Spacecraft Orientation Original
Binary Data Collection
Short Name:
PVO-PHEM-BIN
Date:

Publisher:
Planetary Data System
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).
Quasi Thermal Noise pectroscopy on High Frequency Receiver Data Data
Collection
Short Name:
cassini_rpws_hfr
Date:

Publisher:
Planetary Data System
Description:
This collection contains RPWS-HFR Quasi Thermal Noise (QTN)
spectroscopy supplied CDF files containing a time series of thermal
plasma moments (density and temperature). QTN data products are
generated only when the QTN analysis is applicable.
