Dear colleagues,

Please find hereafter information about recent events and updates on DORIS =
missions and corresponding data:

1/ SATELLITE EVENTS & DATA GAP:

*       Hy-2A Orbit Modification on 23rd March 2016

      On March 23rd 2016, Hy-2A satellite moved from its nominal orbit to a=
 geodetic orbit. The new orbit is now about 2 km higher, has a 168 day-cycl=
e with 2315 orbits in the full cycle. =3D=3D>    this lead to a gap of  HY2=
A DORIS data between 2016/03/15 and  2016/03/23

*       JASON3 : Due to the onboard GPS software upgrade, the DORIS mission=
 was interrupted which lead to  a DORIS data  gap from 2016/03/15 07:10:36 =
TAI to 2016/03/17 07:54:36 TAI

*       JASON2:  as for Jason2, the DORIS instrument  was interrupted due t=
o the onboard GPS software upgrade, which lead to  a DORIS data  gap  from =
2016/04/05 13:30:36 TAI to 2016/04/06 13:52:36 TAI

All these DORIS events  are summarized on the " DORIS event table" availabl=
e on the IDS website at: http://ids-doris.org/system/table-of-the-events.ht=
ml


2/ Re-processing of  Jason2  solar panel angles for cycle 1-4 :

The Jason2 Solar Array Pointing Angles for the cycle 1-4 have been updated =
at IDS data centers CDDIS and IGN,  since previous values were incorrect. T=
he data corresponding to this period (from 2008/06/20 to 2008/08/22)  have =
been gathered in an unique file, instead of many files every 36h that were =
removed.

The new file is available at:
CDDIS :
ftp://cddis.gsfc.nasa.gov/pub/doris/ancillary/quaternions/ja2/2008/ja2qsolp=
_20080620000000_20080823000000.001

IGN:

20000000_20080823000000.001
