Investigating software specific dependencies within theintra-technique VLBI combination

Autor: Hellmers, Hendrik, Modiri, Sadegh, Bachmann, Sabine, Thaller, Daniela, Bloßfeld, Mathis, Seitz, Manuela

The IVS Combination Centre generates and releases the combined VLBI products of the International VLBI Service for Geodesy and Astrometry (IVS). These solutions are generated session-wise by applying an intra-technique combination of the individual c

Predicting Earth orientation parameters: a study on the accuracy of the predicted EOP using technique-specific and multi-technique combined EOP products

Autor: Modiri, Sadegh, Thaller, Daniela, Hellmers, Hendrik, Klemm, Lisa, König, Daniel, Flohrer, Claudia, Walenta, Anastasiia, Bachmann, Sabine

Publikováno v: XXVIII General Assembly of the International Union of Geodesy and Geophysics (IUGG)

Accurate estimation of Earth Orientation Parameters (EOP) is critical for various applications in navigation, geodesy, geophysics, and environmental monitoring. Real-time EOP data allow for timely updates to navigation systems, ensuring their continu
