*************************************************************************** IERS Message No. 17 December 6, 2001 *************************************************************************** FIRST ANNOUNCEMENT IERS WORKSHOP on the IMPLEMENTATION of the NEW IAU RESOLUTIONS The International Earth Rotation Service (IERS) will organize a workshop devoted to the implementation of the IAU XXIV General Assembly recommendations on reference systems. The workshop will be held at the Paris Observatory, April 18 - 20, 2002. Background During its XXIV General Assembly in August 2000 the IAU agreed to new resolutions. Namely, the new precession-nutation model was adopted, and the new Celestial Intermediate Pole, Celestial and Terrestrial Ephemeris Origins were defined. As a result the whole spectrum of products within the IERS will be affected. The new resolutions should become effective on January 1, 2003. This workshop is organized to establish the changes in IERS products and analyses that will be required in order to comply with the IAU recommendations. It is anticipated that the structure will be in the nature of a workshop with only a few traditional style presentations. For practical implementations and almanac work it is necessary to - develop a clear explanation of the concepts of the new celestial transformation and the relation to the conventional transformation, - explain the use of the precession-nutation model IAU 2000 A / B, - plan the necessary changes in the data services that will be required, - demonstrate software for the actual implementation of the new systems by users. All researchers and specialists working in field of interest are kindly invited to participate actively in the workshop. A follow-up second announcement with a detailed program will be released in the first half of January 2002 to those who return, not later than December 31, 2001, the attached pre-registration form by mail, fax or e-mail to IERS Central Bureau Subject: Workshop 2002 Bundesamt fuer Kartographie und Geodaesie Richard Strauss Allee 11 D-60598 Frankfurt / Main Germany Fax: #49-69-6333-425 e-mail: central_bureau@iers.org --------------------------------------------------------------------------- IERS WORKSHOP on the IMPLEMENTATION of the NEW IAU RESOLUTIONS Pre-registration form Name: Address: Phone: Fax: E-mail: [ ] I intend to participate in the workshop.
