Dear IDS analysts,

I would like to inform you that precise orbits in the GDRD standards
have been delivered to the CDDIS/IGN data servers. 
For the time being the reprocessed orbits concern the Envisat and Cryosat 
satellites, and are flagged with a version number 02 in the file name. 
For example: 
/pub/doris/products/orbits/ssa/en1/ssaen102*
/pub/doris/products/orbits/ssa/cs2/ssacs202*

Jason-1 POE orbits will switch to the GDRD standards from the first arc 
after the orbit change. All reprocessed orbits will be delivered soon 
after the change (end of june at the latest).  

Jason-2 POE orbits will switch to the GDRD standards at a later stage, 
somewhere in june, to phase the change in the orbit standards 
with the change in the altimetery processing standards. 

HY2A orbits have been produced in GDRD standard from the first arc. 

Spot5 orbits are in GDRD standards since arc 361 (ssasp501.b12020.e12031.D__.sp3.001.Z)
Spot4 orbits are in GDRD standards since arc 549 (ssasp401.b12021.e12032.D__.sp3.001.Z)
Past Spot satellites orbits will not be reprocessed. 

You will find in attached PDF a brief summary of the most significant changes 
between the previous and the new POD standards. 

Have an great weekend, and sorry for any crossposting. 

Luca
