Project

Analysis of Earth orientation parameters measured by astrometric and modern space techniques (IAA3003205)

The Earth orientation parameters that we recently derived from optical astrometric measurements in the interval 1899.7 - 1992.0 in the Hipparcos reference system will be further improved, especially by using more accurate proper motions<...
