See the page IDS data structure and formats for information about file naming conventions and data centers structure.

Data and products are mainly stored at IDS Data Centers, CDDIS (HTTPS authenticated access) and IGN FTP site (ftp://doris.ign.fr/pub/doris/), and at IDS Central Bureau (FTP ftp://ftp.ids-doris.org/pub/ids/ and HTTPS https://ids-doris.org/documents/BC/).

(*) NB: the precision of the position/velocity delivered in the sp3 format is extended with one digit (e.g., moving to f14.7 in ‘P’ and ‘V’ blocks) in ssa orbit files from serie VV=30 (eg. ssaja330....; see Data-Structure-Formats.pdf). This change is not documented in the sp3c description.
