IERS Central Bureau -

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.
