Research

The four main space geodetic techniques are combined to determine global terrestrial reference frames (TRFs). Currently available global TRFs do not meet the necessary accuracy requirements defined by the Global Geodetic Observing System of 1mm accuracy and 1mm/decade stability. We investigate different combination strategies (“local, global, space and clock ties”), and technological and conceptional developments in the space geodetic techniques.

Main research areas

  • Local ties, e.g., Glaser et al. (2015a1 , 2019b2)
  • Global ties, e.g., Glaser et al. (2015b3)
  • Space ties, e.g., Delva et al. (20234), Schreiner et al. (REFAG2022)
  • Clock ties
  • Additional network stations, e.g., Glaser et al (2019a5)
  • Next-generation GNSS, e.g., Glaser et al. (2020a6), Raut et al. (20237), Schreiner et al. (IUGG20238)
