What's new on DORIS

New point at Rothera (see dorismail 1108)

Data availability during last Jason-2 Safe Hold Mode (see dorismail 1105)

Antenna replacement at Sal (Cape Verde Islands) (dorismail 1091)

Data availability during recent periods of Safe Hold Mode of Jason-2: DORIS1B data and the satellite orbits are not delivered; DORIS/Rinex are disseminated to IDS (as well as the solar panel / attitude quaternions files) but with a degraded quality because of the SHM and the non-nominal attitude law (see dorismail 1087). 

Jason-2 in Safe Hold Mode since 2017/09/14 07:13:04 UTC. More information on Jason-2 status in dorismail 1080

Local tie file updated (see dorismail 1079). Also reachable through the Documents page (section "Stations")

Jason-2 information from last JSG held on June  20^th in dorismail 1075

Antenna change at Sal (Cape Verde Islands) (dorismail 1074)

Jason-2 in Safe Hold Mode since 2017/05/17 22h26:57 UTC. More information on Jason-2 status in dorismail 1073

Jason-2 was in Safe Hold Mode from March 15, 2017 to March 29, 2017. No DORIS 2.2 data and no orbit for this period. RINEX files available during that period but with some gaps (see dorismail 1071)

New point at Socorro (see dorismail 1068)

New file of tie vectors from DORIS to other techniques is now available (see dorismail 1050).
Also reachable through the Documents page (section "Stations").

DORIS station in the Gavdos Island, Greece, has been completely removed (dorismail 1048)

Jason-2 has been moved to be placed in a interleaved orbit with respect to Jason-3 orbit. The period of the corresponding manoeuver is between October 2 and October 12, 2016 (see dorismails 1045 1046)

--> No orbit and no DORI2.2 data are available on IDS data Centers during this period, but the RINEX-DORIS are available

Jason-2 moved to the interleaved orbit in early October (see dorismail 1042)

Local tie file updated (see dorismail 1041). Also reachable through the Documents page (section "Stations")
