Aug 16, 2018 · The new C04, referred to as IERS EOP 14C04, is aligned onto the most recent versions of the conventional reference frames (ITRF 2014 and ICRF2). Additionally, the combination algorithm was revised to include an improved weighting of …

The eop module provides data structures and functions for the updating, loading, and use of Earth orientation parameter (EOP) data. Earth Orientation Parameters are empirically observed, estimated parameters that describe the irregularities in Earth's rotation in space.

The objective of this web site is to distribute the International Terrestrial Reference Frame (ITRF) products. ITRF94 , ITRF96 , ITRF97 , ITRF2000 , ITRF2005 , ITRF2008 , ITRF2014 , ITRF2020 and ITRF2020-u2023 solutions are available for download.

These series result from a combination of operational EOP series derived from VLBI, GNSS, SLR, and DORIS. The C04 series were updated to provide EOP series consistent with the set of station coordinates of the ITRF 2014. The new C04, referred to as IERS EOP 14C04, is aligned onto the most recent versions of the conventional reference

Step 2: EOP series are made consistent with the ICRF and ITRF. Any reference EOP has to be consistent with the International Celestial Reference Frame (ICRF) and the International Terrestrial Reference Frame (ITRF).

The Earth Orientation Parameters (EOP) are the parameters representing the rotational part of the transformation between the current releases of the International Celestial Reference Frame (ICRF) and the International Terrestrial Reference Frame (ITRF).

The new C04, referred to as IERS EOP 14C04, is aligned onto the most recent versions of the conventional reference frames (ITRF 2014 and ICRF2). Additionally, the combination algorithm was revised to include an improved weighting of the intra-technique solutions.

These files contain datum-free normal equations with station coordinates, source positions, and full sets of Earth Orientation Parameters (EOP).

Jun 2, 2009 · The ITRF2005 is the first rigorous combination ensuring ITRF and EOP consistency, based on time series of station positions and Earth Orientation Parameters (EOPs).

Following the procedure already used for previous ITRF solutions, the ITRF2020 uses as input data time series of station positions and Earth Orientation Parameters (EOPs) provided by the Technique Centers of the four space geodetic techniques (VLBI, SLR, GNSS and DORIS), as well as local ties at colocation sites. Based on completely reprocessed ...
