DTRF2020-u2023 Datum Realization

The Geodetic Datum of DTRF2020 is realized according to the definition of the ITRS, see IERS Conventions (Petit and Luzum, 2010).

• The origin is realized in the center of mass of the Earth.
• The scale is realized consistently to the unit of length, the meter (SI).
• The orientation is consistent with that of the BIH Terrestrial System (BTS) at epoch 1984.0 (BIH: Bureau International de l'Heure).

The DTRF2020-u2023 datum is realized as for DTRF2020:

• The origin is realized from the full SLR input data series.
• The scale is relalized from the full input data series of VLBI and GNSS.
• The orientation is realized by aligning DTRF2020-u2023 to DTRF2014.
