Proceedings of the Second Earth Orientation Parameters Prediction Comparison Campaign (2nd EOP PCC) Workshop


Overview. Many advanced geodetic and astronomical tasks, including precise positioning on Earth, pointing astronomical instruments, and navigation of deep-space satellite missions, require accurate measurements and predictions of Earth Orientation Parameters (EOP). Therefore, many institutions around the world process geodetic observations to obtain estimates for the EOP with short latencies as a basis for the subsequent prediction. However, EOP forecasts delivered by various research centres deviate from each other due to the use of different input data and methods. A first comprehensive comparison and assessment of the various EOP forecasting methods was provided by the EOP Prediction Comparison Campaign, which operated between 2006 and 2008. However, since that time, many achievements were made in terms of both improved geodetic data processing and advanced prediction methods. In light of this progress, a re-assessment of the various EOP prediction capabilities will be pursued in the frame of the 2nd Earth Orientation Parameters Prediction Comparison Campaign (2nd EOP PCC). The new campaign was prepared by the Office run by Centrum Badań Kosmicznych Polskiej Akademii Nauk (CBK PAN) in cooperation with GeoForschungsZentrum (GFZ) and under the auspices of the International Earth Rotation and Reference Systems Service (IERS). The campaign officially launched in September 2021 and will run at least until the end of 2022. The first Workshop of the 2nd EOP PCC was held online on February 15-16, 2022 and aimed at presenting the current state of the campaign and receiving feedback from participants.


Details and requirements. This Special Issue is composed of peer-reviewed proceedings of the 2nd EOP PCC Workshop. It deals primarily with topics related to determinations, analyses, and predictions of EOP, as well as discussions on methods and reference data for EOP prediction validation.

Manuscripts should be prepared in a journal template and should be no more than 15 pages long.
