Abstract
Spatiotemporal datum can provide geometric information and spatiotemporal distribution information of geographic space, and enable satellite users to master detailed spatiotemporal situation of spatial geography. In this paper, from the perspective of ground observation, considering the influence of several spatial factors, the high-precision spatiotemporal reference model including the description of the spatial reference system and its transformation model and the high-precision spatiotemporal reference model including the description of time reference system and time system, the transformation of coordinate system and the method design of astrometry correction are derived. This method can provide geometric information and spatial and temporal distribution information of high-precision geographic space and lay a theoretical foundation for subsequent space applications.
