Dear Collea= gues,

 =

Following t= he DORISmail 1433 (Alexandre Couhert),  here is the current status

regarding t= he delivery of the orbits in POE-G standard:

 =

- POE orbit= s are now determined with POE-G standards for Jason3, Sentinel-3A, Sentinel= -3B and Sentinel-6A 

POE-G files= are identified by the version number VV=3D30 in the file name

  

- Complete = reprocessing according to POE-G standards was delivered in April for Sentin= el-6A,

and today f= or Sentinel-3A and Sentinel-3B.

For these m= issions, POE-F series (marked with version number 20) have been moved to se= parate directories (./POE-F)

 =

Reprocessin= g for Jason-3 will be provided later this year.

 =

The files a= re available at IDS Data Centers:

Dear colleagues,

 

The first Jason-3 precise orbi= ts (cycle 500) in the new POE-G standards

(previously POE-F standards) w= ere delivered last Monday and will soon be

available in sp3 to the CDDIS/= IGN data servers. They are flagged with the

version number VV=3D30 in the = file name.

 

We use this opportunity to upd= ate the header of our sp3 files accordingly,

 

/* PCV:IGS20   =             &nb= sp;            =             &nb= sp;

/*    &nbs= p;            &= nbsp;           &nbs= p;            &= nbsp;           &nbs= p;  

 

to clarify the handling of geo= center motion, as discussed within the Copernicus

Quality Working group. See att= ached for details. As you will see, we also

extended with one digit the pr= ecision of the position/velocity delivered in

the sp3 format (e.g., moving t= o f14.7 in ‘P’ and ‘V’ blocks).

 

Sentinel-6 MF POE orbits will = switch to the POE-G standards in April, as

well as Sentinel-3A/B.<= o:p>
