ESA declares end of mission for Envisat (or see dorismail 820)

Status of Jason-1 and Operations in the Geodetic Orbit (see dorismail 818)

Antenna change at Rio Grande (see dorismail 812)

Spot-5 celebrates 10 years in orbit

Envisat celebrates its 10th birthday

Jason-1 depletion manoeuvers (see dorismail 774)

Successful launch for HY-2A (see dorismail 765).

The Chinese Haiyang-2A oceanographic satellite with DORIS onboard was successfully launched on August 15, 2011 at 22:57 UTC, from the Taiyuan Satellite Launch Center, China. The launch was carried out by a Long March 4B (Chang Zheng-4B).

 

Antenna change and raising at Noumea (see dorismail 768)

Antenna change at Rikitea (see dorismail 769)

Antenna change at Terre Adélie (see dorismail 754)

Station renovation at Kourou (see dorismail 755)

Antenna change and raising at Rothera (dorismail 743)

The DORIS stations in Monument Peak (dorismail 728) and Fairbanks (dorismail 729) are declared closed.

A new DORIS station installed in Cold Bay (Alaska peninsula) (dorismail 718). It replaces Fairbanks station which has been down since July 2010 and removed on October, 7th.

ENVISAT orbit change: 3 pairs of in-plane maneuvers performed between October 22 and November 2, 2010.

See dorimail 714 for changes in the cycle/ arc number and length of the delivered DORIS data

IGN provides IDS with a new DORIS internal tie file including vectors between successive antenna locations on the same site (see dorismail 709).

ENVISAT orbit change for extended lifetime (dorismail 703). The ENVISAT orbit will be changed in order to extend the mission until 2014 (3-year extension). The adopted solution is to abandon inclination control ensuring a reduction in hydrazine consumption. Thus, 3 pairs of  in-plane maneuvers (OCMs) will be performed between October 22 and November 2, 2010 

Redelivery of 1998 SPOT4 DORIS files (dorismail 701)

DORIS Cryosat-2 data available at IDS Data Centers (see dorismail 681)

Network/ station renovation at Ascension (dorismail 679)

CNES- SSALTO/ POD team ready to deliver POE orbits in sp3c format to the IDS Data Centers (see dorismail 670) 

Error on phase center position in Jason-2 RINEX/ DORIS data (see dorismail 665).

First data made by DORIS on Cryosat-2

Jason-3 is well under way.

Error on Jason2 DORIS1B data in the ionospheric correction field: a new version of all files (cycle 1 up to cycle 57)  will be made available on the IDS data centers at CDDIS and IGN (see dorismail 648).

DORIS 20th Anniversary
The DORIS system is 20 years old in 2010 and it celebrates a technical, operational and scientific success in the precise determination of satellite orbit (...)
Developed in the early eighties by CNES and IGN (Institut Géographique National) teams with Scientifics from GRGS (Groupe de Recherche en Géodésie Spatiale) and industry, DORIS was first tested on the SPOT-2 satellite, launched on the 22nd January 1990. (...) (see dorismail 643)

Network/ station renovation at Krasnoyarsk (dorismail 641)

December 2009

Jason-1 celebrates its 8th anniversary! 

Papeete DORIS station: 4th Master Beacon of the Network (see dorismail 632)

Spot4 orbit change. In order to avoid the conflicts and the jammings between SPOT4 and SPOT5 led by the link of 2 satellites, it is intended to  move the satellite SPOT4 on its orbit (see dorismail 634 for details)
