Inquiry Regarding Jason-2 Satellite Attitude

by abd_ruby87 » Sun Jan 21, 2024 10:40 pm America/New_York

Dear NASA Distributed Active Archive Centers,
I wish you all good health. I trust this letter finds you well. I am writing to seek clarification and guidance regarding the use of the attitude of the Jason-2 mission. The quaternion data is available at the following link: https://cddis.nasa.gov/archive/doris/ancillary/quaternions/ja2/.
My inquiry is related to the nature of the Jason-2 attitude represented in quaternions (attachment photo). Specifically, does the quaternion data provided signify the transformation from the Satellite Body Reference System (SBRS) to the Earth-centered inertial (ECI) reference system, or vice versa (transform ECI to SBRS)?
Thank you for your contribution to the scientific community, and I eagerly await your response.
Sincerely,

Abdelrahim Ruby

Dear Abdelrahim,

There is some documentation on the IDS website at https://ids-doris.org/analysis-coordination/documents-related-to-data-analysis.html and at https://ids-doris.org/documents/BC/ancillary/quaternions/jason1_2_3_quaternion_solar_panel.pdf that might help.

If you need more information, please contact the IDS Central Bureau.

Sincerely,

Lori
