Dear CHAMP GPS data user,

Special circumstances have let to the CHAMP project decision to provide
as of today all GPS level-1 data (including radio occultation data) to
interested investigators, even prior to the planned full validation of
in particular the occultation data.
The CHAMP Project Management would like to make clear that the
NASA/JPL-provided GPS onboard software has still known deficiencies and
bugs, even after a great number of software changes and uploads which
effect the quality and quantity of a routine GPS data flow for POD,
atmospheric and ionospheric occultations.

An expected date for the full performance of the GPS flight receiver
software can presently not be provided.

The level-1 GPS data will be made available through the CHAMP ISDC
immediately after data decoding. For details about the content and the
availability of the data see the product description pages of the CHAMP
ISDC at: http://isdc.gfz-potsdam.de/champ/

Best regards,

Christoph Reigber, CHAMP project director
Hermann Luehr, CHAMP operations manager
Peter Schwintzer, CHAMP science data manager
