Appendix 4: IERS Retreat summary (Noomen)

          • Represent space geodesy and individual space geodetic techniques
          • Combine best elements of individual techniques
          • Continue, expand an d improve current products
          • Possible “new” fields/products: geocenter (explicitly), planetary “geodesy”, relativistic products, orbits


  • Absolute station coordinates, velocities

  • Geocenter, scale

  • Earth Orientation Parameters

  • Validation and calibration GPS/GLONASS spacecraft parameters (phase centers)

  • Validation and calibration gravity field solutions

  • Validation of parameters/models (troposphere, relativity, tides, …)


  • Analysis standards

  • Station (inter-technique) site ties (incl. validation)

  • Rapid provision of coordinates of new stations

  • Political support

IERS Retreat: IERS Combination Pilot Project
(evolves from IERS SINEX combination campaign)
rigorous combination of networks + EOPs + quasars:

- IERS technique centers (combination product, or 1 individual solution)

- combination solutions at measurement level

  • 4-6 weeks delay

  • timeline:

- May 1, 2003: installation of Combination WG

- end of June: release of CFP

- Sep 15: deadline for proposals

- beginning Oct: evaluation of proposals

- Jan 1, 2004: start of pilot project

  • eventually, combination product will replace (that of) IERS PCs

  • eventually reprocess old SLR, VLBI, GPS, … data

  • time-series of weekly solutions, evolve into multi-year solution

IERS Retreat: discussion group on “techniques”
Bruyninx, Noomen, Nothnagel, Weber
Analysis topics:

  • ocean tidal loading: IERS to recommend conventional model (users: or better) => action item “SBL” and “Conventions”

  • atmospheric pressure loading:

- values at station and/or grid (interpolation), 6h resolution, max 7 days latency => action item “SBL”

- regression coefficients

- IERS to define reference pressure

  • update conventions (per chapter) when necessary and timely


  • geocenter: definition and requirements => action item Noomen: initiation and testbed various techniques


  • GPS at all sites => action item Services
  • GPS Core stations => action item IGS

  • barometer readings and dissemination => action item IGS

IERS Retreat: miscellaneous (1)

Gambis: format change C04 / Bulletin B
