(EN) Terrestrial Reference Frames - Connecting the World through Geodesy

Description of Terrestrial Reference Frames: https://ggos.org/item/terrestrial-reference-frame/ ITRF website: https://itrf.ign.fr UN-GGRF: https://www.unggrf.org/ This film demonstrates the importance of geodetic terrestrial reference frames to science and society. The tremendous social benefits of long-term, stable, and accurate reference frames will continue to fuel innovative location-based applications – with all this based on data from four different but interconnected geodetic techniques (VLBI, SLR, GNSS und DORIS). The next time you use your smartphone for navigation, remember that your position is one point on a vast, international terrestrial reference frame, with Geodesy as your guide. 00:00 Why Terrestrial Reference Frames? 01:29 What is a Terrestrial Reference Frame? 02:34 GGRF - Global Geodetic Reference Frame 04:03 ITRF - International Terrestrial Reference Frame 04:42 How is a Terrestrial Reference Frame built? 07:10 How ITRF helps us understand our dynamic planet? 08:36 Regional Terrestrial Reference Frames 09:29 Closing 10:06 Final Credits This video was produced by the Coordinating Office of the Global Geodetic Observing System (GGOS) of the International Association of Geodesy (IAG) at the Federal Office of Metrology and Surveying (BEV) in Vienna, Austria, and with the contribution of Martin Sehnal, Allison Craddock, Detlef Angermann, Laura Sánchez, Zuheir Altamimi, Peter Steigenberger, Harald Schuh and Richard Gross.
