Satellite quaternion files (doi:10.5067/DORIS/DORIS_IDSQUAT_001) used to represent the satellite's attitude are available for selected satellites equipped with Doppler Orbitography by Radiopositioning Integrated on Satellite (DORIS) receivers:
- Jason-1
- Jason-2
- Jason-3
- Satellite with ARgos and ALtiKa (SARAL)
Two files are provided on a daily basis, one for the satellite bus and one for the solar panels.
The starting directory and file naming convention for these files can be found below.
