The README File (README_SP3_GSC.txt) at the data centers will be updated in due cours= e. Over the S6A/S6B tandem mission period the average radial RMS orbit differe= nces with CNES (POEG) and the JPL (GPS, IGS20) orbits are as follows: Jason-3 (GSFC, std2400) vs CNES-POEG: avg. 5.60 mm S6A (GSFC, std2400) vs. JPL (IGS20): avg 4.61 mm S6B (GSFC, std2400) vs. JPL (IGS20): avg. 4.71 mm (from S6B cycle 11) As discussed in the POD splinter of the OSTST in Wiesbaden (June 2026), S6B is subject to outgassing in the early cycles which degrades the POD, and it seems to take until S6B cycle 11 for the outgassing effects to be mu= ch reduced/ From S6B cycle 11, our arc-adjusted Cr values for S6A and S6B are in very c= lose agreement, Jason-3: gscja322.b26176.e26186.D_S.sp3.001.Z gscja322.b26098.e26107.D_S.sp3.001.Z gscja322.b26186.e26199.D_S.sp3.001.Z gscja322.b26107.e26110.D_S.sp3.001.Z gscja322.b26196.e26207.D_S.sp3.001.Z gscja322.b26108.e26119.D_S.sp3.001.Z gscja322.b26206.e26217.D_S.sp3.001.Z gscja322.b26118.e26129.D_S.sp3.001.Z gscja322.b26216.e26218.D_S.sp3.001.Z gscja322.b26128.e26139.D_S.sp3.001.Z gscja322.b26218.e26229.D_S.sp3.001.Z gscja322.b26138.e26149.D_S.sp3.001.Z gscja322.b26226.e26237.D_S.sp3.001.Z gscja322.b26148.e26159.D_S.sp3.001.Z gscja322.b26236.e26238.D_S.sp3.001.Z gscja322.b26157.e26168.D_S.sp3.001.Z gscja322.b26167.e26174.D_S.sp3.001.Z gscja322.b26175.e26176.D_S.sp3.001.Z Sentinel-6A gscs6a22.b26183.e26194.D_S.sp3.001.Z gscs6a22.b26093.e26104.D_S.sp3.001.Z gscs6a22.b26193.e26204.D_S.sp3.001.Z gscs6a22.b26103.e26114.D_S.sp3.001.Z gscs6a22.b26203.e26214.D_S.sp3.001.Z gscs6a22.b26113.e26124.D_S.sp3.001.Z gscs6a22.b26212.e26223.D_S.sp3.001.Z gscs6a22.b26123.e26134.D_S.sp3.001.Z gscs6a22.b26222.e26233.D_S.sp3.001.Z gscs6a22.b26133.e26140.D_S.sp3.001.Z gscs6a22.b26232.e26239.D_S.sp3.001.Z gscs6a22.b26140.e26145.D_S.sp3.001.Z gscs6a22.b26239.e26245.D_S.sp3.001.Z gscs6a22.b26143.e26154.D_S.sp3.001.Z gscs6a22.b26153.e26164.D_S.sp3.001.Z gscs6a22.b26163.e26174.D_S.sp3.001.Z gscs6a22.b26173.e26184.D_S.sp3.001.Z Sentinel-6B gscs6b22.b26123.e26134.D_S.sp3.001.Z gscs6b22.b25350.e25362.D_S.sp3.001.Z gscs6b22.b26133.e26140.D_S.sp3.001.Z gscs6b22.b25359.e26005.D_S.sp3.001.Z gscs6b22.b26140.e26145.D_S.sp3.001.Z gscs6b22.b26004.e26015.D_S.sp3.001.Z gscs6b22.b26143.e26154.D_S.sp3.001.Z gscs6b22.b26014.e26025.D_S.sp3.001.Z gscs6b22.b26153.e26164.D_S.sp3.001.Z gscs6b22.b26024.e26035.D_S.sp3.001.Z gscs6b22.b26163.e26174.D_S.sp3.001.Z gscs6b22.b26034.e26045.D_S.sp3.001.Z gscs6b22.b26173.e26184.D_S.sp3.001.Z gscs6b22.b26044.e26055.D_S.sp3.001.Z gscs6b22.b26183.e26194.D_S.sp3.001.Z gscs6b22.b26054.e26055.D_S.sp3.001.Z gscs6b22.b26193.e26204.D_S.sp3.001.Z gscs6b22.b26055.e26066.D_S.sp3.001.Z gscs6b22.b26203.e26214.D_S.sp3.001.Z gscs6b22.b26064.e26075.D_S.sp3.001.Z gscs6b22.b26212.e26223.D_S.sp3.001.Z gscs6b22.b26074.e26085.D_S.sp3.001.Z gscs6b22.b26222.e26233.D_S.sp3.001.Z gscs6b22.b26084.e26095.D_S.sp3.001.Z gscs6b22.b26232.e26239.D_S.sp3.001.Z gscs6b22.b26093.e26104.D_S.sp3.001.Z gscs6b22.b26239.e26245.D_S.sp3.001.Z gscs6b22.b26103.e26114.D_S.sp3.001.Z gscs6b22.b26113.e26124.D_S.sp3.001.Z Get Outlook for Mac --_000_BY3SPR01MB00050E967D78917623E5474AC9932BY3SPR01MB0005na_
Dear Colleagues:

We have extended the std2400 (DORIS+SLR) orbit time series for Jason-3 and = Sentinel-6A by delivering the 
 following orbits to the IDS data centers (CDDIS & IGN). In additi= on, we deliver Sentinel-6B orbits
 for the entire tandem mission, starting shortly after its entry to th= e mission orbit. The README
File (README_SP3_GSC.txt)  at the data centers will be updated in due = course.

Over the S6A/S6B tandem mission period the average radial RMS orbit differe= nces with
 CNES (POEG) and the JPL (GPS, IGS20) orbits are as follows:

Jason-3 (GSFC, std2400) vs CNES-POEG:  avg. 5.60 mm
S6A (GSFC, std2400) vs. JPL (IGS20): avg  4.61 mm
S6B (GSFC, std2400) vs. JPL (IGS20): avg. 4.71 mm (from S6B cycle 11)

As discussed in the POD splinter of the OSTST in Wiesbaden (June 2026),&nbs= p;
 S6B is subject to outgassing in the early cycles which degrades the P= OD, 
and it seems to take until S6B cycle 11 for the outgassing effects to be mu= ch
reduced/

From S6B cycle 11, our arc-adjusted Cr values for S6A and S6B are in very c= lose agreement,

Jason-3:
