  GPS-PDR Version A Product Description, Feb. 2007 Release 
Description: The products described in this document are based on the homogeneous and complete reprocessing of a global GPS network. This project is a joint effort (funded by the German Research Foundation DFG) of Forschungseinrichtung Satellitengeodäsie (FESG) of University of Technology Munich (TUM) and Institut f¨r Planetare Geodäsie (IPG) of University of Technology Dresden (TUD) in cooperation with GeoForschungsZentrum (GFZ) Potsdam. An earlier version of the reprocessing is described in Steigenberger et al. (2006). This paper should also be cited when using any of the products described in this document.

SPECIAL NOTE ON GPS-PRN32 and LEVEL-1 READ SOFTWARE

The GPS satellite PRN32 (SVN23) was set "healthy" as of Feb 26, 2008.
Tracking of this satellite was therefore enabled on GRACE.
The Level-1B data since Feb 26, 2008 contains GPS tracking data from PRN32.

The software to convert from GRACE GPS1x format to Rinex format has been
updated to handle the presence of data from PRN32.

Users should download and re-install the entire Level-1 Read software suite
(RELEASE_2008-03-20) from the GRACE archives.


This software is backwards compatible and can process all mission data.
