ST 2



ST 2, a Singaporean/Taiwanese communications satellite, was launched from Kourou on 20 May 2011 at 20:38 UT by an Ariane 5 rocket. The satellite weighed 5.09 tonnes and will replace and expand communications services provided by ST 1, which is now at the end of its design life. The craft's final position in geosynchronous orbit will be at 88 degrees E longitude. ST 2's communications payload includes six antennas, 41 Ku-band transponders and 10 C-band transponders. The satellite will provide internet-based fixed and mobile communications services for customers in Asia, the Middle East and the Indian subcontinent. The satellite is expected to go into operational service in July and has a design life of 15 years.
