Missions of the EOP Product Centre of the International Earth Rotation and Reference Systems Service (IERS):
- Collect through the world the time series of the Earth Orientation Parameters (EOP):
- pole coordinates (x,y)
- universal time (UT1-UTC, UT1-TAI) or length-of-day offset LOD
- Celestial pole offsets (Dpsi, Deps)
These time series are derived from the various astro-geodetic techniques (LLR, SLR, GPS, VLBI and DORIS).
- Archive EOP and make them avaible through FTP/WEB
- Analyse EOP and in particular monitor their consistencies
with respect to the international terrestrial and celestial referene
frames.
- Compute combined standard solution for EOP:
Bulletin B or
IERS C04 solution (daily since 1962), and IERS C01 solution (0.05 year sampling since 1846)
- Compute and make available DUT1 (Bulletin
D) and leap second announcements (Bulletin
C).
Applications
- astrometry
- geophysics
- space geodesy
- orbit determination
- timing
- positioning
For users interested in the rapid and predicted EOP, refer to
Bulletin A provided by the IERS Rapid Service/Prediction Center located
at USNO.
