IERS SINEX Combination Campaign - First Report


Dear colleagues,

The IERS SINEX Combination Campaign was started in May and we would like
to inform you about the status quo of this campaign.

Altogether, we received 11 proposals for this campaign. Splitted in the
two steps of the campaign, the participating groups are the following:

1) First step only (generation of SINEX files):

- AIUB (Urs Hugentobler)
  urs.hugentobler@aiub.unibe.ch
- BKG (Gerald Engelhardt, Volkmar Thorandt)
  engelhardt@leipzig.ifag.de
- FFI (Per-Helge Andersen)
  per-helge.andersen@ffi.no

2) Second step only (Combination of SINEX files):

- FESG (Markus Rothacher)
  Markus.Rothacher@bv.tum.de
- GFZ (Shengyuan Zhu)
  zhu@gfz-potsdam.de
- IGN (Zuheir Altamimi)
  altamimi@ensg.ign.fr
- University of Newcastle-upon-Tyne (Konstantin Nurutdinov)
  Konstantin.Nurutdinov@ncl.ac.uk

3) Both steps:

- ASI (Giuseppe Bianco)
  giuseppe.bianco@asi.it
- DGFI (Detlef Angermann)
  angerman@dgfi.badw.de
- JCET, University of Maryland Baltimore (Erricos C. Pavlis)
  epavlis@JCET.umbc.edu
- Natural Resources Canada (Remi Ferland)
  ferland@geod.nrcan.gc.ca

An overview of all participants including their proposals is available
via the updated website of the IERS Analysis Coordination:

  http://alpha.fesg.tu-muenchen.de/iers/sinex/sinex_campaign.html


If there are some additional groups that want to participate in this
campaign in any way, it is still possible if we get a proposal with the
necessary information. (See 'Call for Participation' at
http://www.iers.org/iers/publications/messages/message_027.txt)


For the participants that proposed to generate SINEX files and had not
already submitted them, please submit your files via our ftp-server:

  alpha.fesg.tu-muenchen.de/incoming/

  Login: anonymous
  Password: your email address

Be aware that you cannot see your submitted files! Therefore, please
send us a short notice via email that you uploaded your files to the
incoming directory, and then we will transfer the files to the
directories of the SINEX data pool. As soon as all proposed files are
available, we will inform you with another email.


Thanks to the help of Zuheir Altamimi from IGN, the SINEX data pool has
been extended with the information concerning the local ties used in the
ITRF2000 combination. A SINEX file for each site is available on the
following ftp-server:

  ftp://lareg.ensg.ign.fr

In the directory .../pub/itrf/itrf2000/tiesnx/ you find:

- the local tie SINEX files per site under the name
  NNNNN.SNX where 'NNNNN' is the 5-digit site DOMES number
- itrf2000.tie: file containing the list of local ties
- 5 SINEX files provided by AUSLIG for the Australian colocation sites,
  together with their DEScription and SUMmary files


We hope that the first step of the campaign can be finalized soon and
the combination part can be started.

With best regards and thanks to all participants,

Daniela Thaller,
Markus Rothacher
