For example see a CHAMP TIVs file: *To: SLR Stations *Fm: GFZ Orbit Prediction System *Op: Automatic Generation *DSIDP CHMP.ORB.PRD IRVS A 030318 GFZ_FITXYZ_950221_IRVS 2003 3 18 0 0 0.0 5518378.031151 -3935387.207021 -298178.098887 8002 2317 1 191.128389423 -292.575145709 7649.830429774 -158 394 0 12580.0 1284812.725242 7548.383673488 ... continued ...

Following a request by the ILRS Central Bureau, GFZ will remove these header lines from all (!) prediction products (i.e. TIVs, DRAG, TLE and SAO files) for CHAMP, ERS-2 and GRACE-A/B in order to harmonize with the standard format specified at the ILRS web site: http://ilrs.gsfc.nasa.gov/products_formats_procedures/predictions/tirv_format.html The planned date of transition to the ILRS standard format at GFZ is April 29th, 2003 00:00 UTC.
