The Jason-3 satellite is in good shape since its launch on 17 January. Pointing is nominal and its thrusters have been activated and calibrated. All instruments—DORIS, Poseidon 3B (which has already ‘pinged’ the surface and had its signals successfully processed by the ground segment), AMR and GPSP (JPL), CARMEN-3/AMBRE (CNES) and LPT (JAXA)—have been switched on and are functioning nominally.
Le satellite Jason-3 va bien depuis son lancement le 17 janvier dernier. Il est en pointage nominal. Ses tuyères ont été activées et calibrées. Tous les instruments sont allumés et fonctionnent normalement : DORIS, POS 3B (qui a fait des échos traités par le segment sol immédiatement avec succès), AMR et GPSP (JPL), CARMEN3/AMBRE (CNES) et LPT (JAXA).
After acquiring millions of pictures of Earth, the SPOT 5 satellite was retired from service between 1 and 11 December. Following a series of 6 orbital manoeuvres to lower its perigee (the point on its orbit closest to Earth), the satellite’s fuel tanks were emptied and its batteries disconnected by CNES teams in Toulouse. It is now stationed safely in an elliptical orbit at an altitude between 625 and 809.
