Description

Satellite quaternion files used to represent the satellite's attitude are available for selected satellites equipped with DORIS receivers:

• Jason-1
• Jason-2
• Jason-3
• Saral

Two files are provided on a daily basis, one for the satellite bus and one for the solar panels.

The starting directory for these files is:

https://cddis.nasa.gov/archive/doris/ancillary/quaternions/

Append the following directory and file names to the starting directory:

sssqbodyYYYYMMDDHHMMSS_yyyymmddhhmnss.LLL

sssqsolpYYYYMMDDHHMMSS_yyyymmddhhmnss.LLL

as described in the table below.

Code	Meaning
sss	3-character satellite code
qbody or qsolp	fixed part (qbody for body quaternions, qsolp (if any) for solar panel quaternions)
