PDS Asteroid/Dust Archive
Dawn Gravity Science
Ceres L-0 (raw)
This data set contains archival raw, partially processed, and
ancillary/supporting gravity science data acquired during the Dawn
mission while the spacecraft was in orbit around the asteroid Ceres.
The radio observations were carried out using the Dawn spacecraft and
Earth-based receiving stations of the NASA Deep Space Network (DSN).
The data set was designed primarily to support generation of
high-resolution gravity field models for Ceres.
Ceres L-2 (reduced)
This data set contains archival results from gravity investigations
conducted during the Dawn mission while the spacecraft was in orbit
around the asteroid Ceres. Radio measurements were made using the
Dawn spacecraft and Earth-based stations of the NASA Deep Space
Network (DSN). The data set includes a spherical harmonic model
of Ceres's gravity field generated by the Jet Propulsion Laboratory,
radial gravity acceleration map, and Bouguet map; these results were
derived from raw radio tracking data.
Superseded versions of this data set:
The superseded version 1 of the data set differed slightly from the coordinate system
used in other Dawn Ceres map products delivered to PDS.
A version 2 of the Ceres L-2 gravity data products
was produced to align the coordinate system with the one utilized
by other Dawn Ceres map products. See the volume aareadme for details
of the coordinate system.
