In this paper possible contributions of classical instrument of time and latitude determinations in the study of geoscience is discussed. Some research results indicate that the observations of the classical instruments contain rich information on geoscience study. They can play a certain role in research of crust structure, plate motion, vertical variation, topography of core-mantle boundary, and in study of seismicity and major earthquake forecasting. It is important that a stable reference system is established and maintained and a relevant observed programme is formulated upon a star catalogue with good quality for geoscience and astro-geodynamics. Some instruments with high precision, especially located in seismic regions, would be continuously operated after the end of their task in ERP determination.
