DORIS - November 2010
ENVISAT orbit change: 3 pairs of in-plane maneuvers performed between October 22 and November 2, 2010.
DORIS - October 2010IGN provides IDS with a new DORIS internal tie file including vectors between successive antenna locations on the same site (see dorismail 709).
DORIS - September 2010
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
