Fermi FT2 Spacecraft Pointing Files

Metadata Updated: December 7, 2023

This utility permits you to download the most current version of the spacecraft (FT2) file predicting the LAT's pointing for a given mission week. The FT2 file is a FITS-formatted file describing Fermi's position and orientation, and thus the LAT's pointing, as a function of time. The FT2 files available here are created in planning Fermi's timeline, and thus provide the observatory's predicted pointing for a given mission week. Files with the string 'PRELIM' in the filename are produced approximately three weeks in advance, while files with 'FINAL' in the filename describe the timeline that will be uploaded to the spacecraft; thus you should use the latter if available. Note that the actual LAT pointing may differ from the predicted as a result of Target-of-Opportunity observations or Autonomous Repoints in response to a bright gamma-ray burst.
