The Magellan Line of Sight Acceleration Profile Data Record
(LOSAPDR) archive (V1.0) contains results from processing of
radio tracking data during Cycles 4, 5, and 6 of the Magellan
spacecraft (superseded by MGN-V-RSS-5-LOSAPDR-L2-V1.13).

| Data Set Abstract |
Line of Sight Acceleration Profile Data Records (LOSAPDR) consist
of data from Doppler tracking of the orbiting spacecraft. The
relative motion of the spacecraft and the earth-based radio
receiver is measured very precisely, and known motions are
removed a priori (i.e. earth rotation, planetary motions,
spacecraft orbital motion, solar pressure, drag), leaving small
velocity changes caused by variations in the mass distribution of
the planet. The residual Doppler frequency shifts are linearly
proportional to the component of velocity in the Earth direction.
Numerical differentiation of these velocity residuals with
respect to time produces line-of-sight (LOS) gravity. These
measures are accelerations at spacecraft altitude which can be
modeled for geophysical interpretation. |
