IERS Conventions (2003)

The IERS Conventions (2003) have been finalized in October 2003. The fully printable version is available as IERS Technical Note 32 and it is expected that the paper version will be available soon. The following list provides the link to each of the chapters for the Conventions and the relevant software. The complete set of files and associated software are available on two identical ftp sites at the BIPM and at the USNO.

Comments and proposals for their evolution are invited through a Questionnaire or should be sent to the principal scientists of the IERS Convention Center, contact Gérard Petit and Brian Luzum.
