****************************************************************************** dorismail 08-Jan-2019 10:44:52 Message No 1158 ****************************************************************************** Author: Ferrage Pascale Subject: Last Jason-2 DORIS DATA unavailability Dear colleagues, Jason-2 was in Safe Hold Mode (SHM) between 2018/12/26 01:33:54UTC and 2019/01/04 at 15:13:33UTC due to a gyro 1 disjunction. During the SHM, the impacts on the dissemination of DORIS data to the IDS Data Centers (IGN/CDDIS) are as follows: - The DORIS system was ON, but the DORIS1B data and the DORIS orbits are not delivered. - The DORIS DATA (in RINEX format) were still disseminated to IDS as well as the solar panel / attitude quaternions files. But note that their quality was degraded because of the SHM and the non-nominal attitude law. Best wishes, Pascale Ferrage ____________________________________________________________________________ De : Marechal Christophe > Envoy=E9 : mardi 8 janvier 2019 08:50 =C0 : ostst@jpl.nasa.gov Cc : Shirtliffe, Glenn M (398A) > Objet : RE: Jason 2 status Dear OSTST members, As expected, Jason-2 has restarted his mission successfully yesterday, Mond= ay, January 7th.
