Concept of a kinematic datum. Transformation of horizontal station coordinates for two separate surveys to reference epoch 2011.00, one for true‐of‐date real‐time kinematic survey situation (t 3 = 2017.65) and one for postprocessing (t2 = 2012.65). Panels show the corresponding displacement grids for north and east components. The same process is used for the vertical component.
