Both definition and realization of vertical reference systems require gravity. Relation between height changes and gravity changes is well known in geodynamics on local, regional, and global scale. Consideration of time as additional dimension is needed in the modern vertical and gravity reference systems as well as in processing both levelling and gravity data. Classical vertical and gravity reference systems are briefly presented followed by the discussion of the need of advanced modification of both systems. Geodynamic aspects in creating modern vertical and gravity reference systems were discussed. The role of geodynamics in the realization of vertical and gravity reference systems was presented with emphasizing the key role of metrology.
