报告摘要：The current IAU model for the Earth's precession-nutation represents a huge improvement with respect to previous models. It has benefited from the use of Very Long-baseline Interferometry (VLBI) observations of extragalactic radio sources for about 20 years, as well as from refined theories and Earth models, and accurate realizations of reference systems.
This lecture will review the concepts, models, equations, observations and parameters on which the IAU 2006/2000 precession-nutation is based and will present the prospects for future improvements in the models. It will also discuss the potential of other techniques, or different types of data, for future improvements of the model.
