Description:
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 continued accuracy. Real-time EOP data is also crucial for studying Earth's rotational behavior, allowing for the tracking of changes in real-time and providing valuable insights into the causes of these changes. Finally, the availability of real-time EOP data enhances the accuracy of space-based observations, leading to improved environmental monitoring and natural resource management. Today, modern high-precision geodetic techniques such as Very Long Baseline Interferometry (VLBI), Global Navigation Satellite Systems (GNSS), and Satellite Laser Ranging (SLR) provide the most accurate possible estimation of the EOP. However, as a result of the complexity and time consumption of the data processing process, delays are always inevitable. Consequently, predicting EOP is of great scientific and practical importance. This study aims to examine the accuracy of EOP prediction based on different EOP products, i.e. technique-specific EOP products, but also a multi-technique combined EOP product provided by the Federal Agency for Cartography and Geodesy (BKG). As part of this study, the comparison of different prediction methods is also considered to determine which method is capable of accurately predicting EOP. The findings of this study provide important information for developing more accurate EOP prediction methods and using single space geodesy in practical applications.
