PDS Information
Find a Node - Use these links to navigate to any of the 8 publicly accessible PDS Nodes.

This bar indicates that you are within the PDS enterprise which includes 6 science discipline nodes and 2 support nodes which are overseen by the Project Management Office at NASA's Goddard Space Flight Center (GSFC). Each node is led by an expert in the subject discipline, supported by an advisory group of other practitioners of that discipline, and subject to selection and approval under a regular NASA Research Announcement.

MGS Accelerometer Archives

About Accelerometer Data Products

Accelerometer data have been released to the Planetary Data System in two phases - a raw data delivery and a reduced data delivery. The volumes are distributed on CD-WO and online at this web site. If you would like a CD, contact Lyle Huber.

The raw data products are found on volume mgsa_0001. The data on this volume are organized according to orbit number. Each orbit provides four files of interest: 1) raw accelerometer counts, 2) orbital elements at periapsis, 3) angular rates and quaternions, and 4) thruster on times.

The reduced data products are found on volume mgsa_0002. The reduced data consist of two different products: 1) a NASA Level 2 data set consisting of the density profile for each orbital pass, and 2) a NASA Level 3 data set consisting of atmospheric properties at constant altitude levels for each orbital pass.

These volumes can also be downloaded via the anonymous FTP server atmos.nmsu.edu, directory PDS/data or /PDS/review.
