The International Terrestrial Reference Frame (ITRF) is our metric of reference and is the main tool used for studying global change. We thus need to determine the ITRF with high accuracy. This is achieved by using ground-based networks of co-located space geodetic (VLBI, SLR, GNSS and DORIS) instruments. The stations hosting all these instruments are called Fundamental Geodetic Observatories. We need to have many such observatories, evenly spaced over the Earth, to obtain more accurate results. We are therefore conducting VLBI simulations and site assessments to determine whether Antarctica and Matjiesfontein offer sites suitable for the establishment of a new geodetic observatory.
