The accuracies of these products are sufficient to support current scientific and technical objectives including the following:
- Fundamental astronomical and geodetic reference systems
- Monitoring and modelling earth rotation/orientation
- Monitoring and modelling deformations of the solid earth
- Monitoring mass variations in the geophysical fluids, including the atmosphere and the hydrosphere
- Artificial satellite orbit determination
- Geophysical and atmospheric research, studies of dynamical interactions between geophysical fluids and the solid earth
- Space navigation.
The IERS accomplishes its mission through the following components:
- Technique Centers: International DORIS Service, International GNSS Service, International Laser Ranging Service, and International VLBI Service
- Product Centers: Earth Orientation Center, Rapid Service/Prediction Center, Conventions Center, ICRS Center, ITRS Center, and Global Geophysical Fluids Center with Special Bureaus for the Atmosphere, for the Oceans, for Hydrology, and for Combination
- ITRS Combination Centers at Deutsches Geodätisches Forschungsinstitut (DGFI), Institut Géographique National (IGN), and Jet Propulsion Laboratory (JPL)
- Analysis Coordinator
- Central Bureau
- Directing Board
- Working Groups: WG on Site Survey and Co-location, WG on SINEX Format, and IAG/IAU/IERS Joint WG on the Consistent Realization of TRF, CRF, and EOP.
Some of these components (e.g., Technique Centers) may be autonomous operations, structurally independent from IERS, but which cooperate with the IERS. A participating organization may also function as one or several of these components (except as a Directing Board).
