Cannes, September 9, 2009 – Thales Alenia Space and Indosat announced today that the Launch Early Operation Phase (LEOP) has been successfully completed and the Palapa-D communications satellite is now in the nominal geostationary orbit (GEO). The solar panels and antennas have been deployed, and the payload in-orbit testing (IOT) phase is ready to start.
太阳能电池板和天线已经打开。
至于卫星是否只有10年寿命，新闻没有提到，以前法国人拒绝评论，称只有在卫星定点后才能估算。
Thales Alenia Space declined to confirm that Palapa-D can be expected to operate for eight to 10 years once in final position, saying a precise estimate cannot be made until the spacecraft reaches its destination.
