Telkom-2 is a geosynchronous communications satellite built by Orbital Sciences Corporation (OSC) for Indonesia's state-owned telecommunications company, PT Telekomunikasi Indonesia Tbk (PT Telkom). Telkom-2 was successfully launched 16 November 2005, at 23:46:00 UTC and positioned in geostationary orbit, at 118° East for replaced Palapa-B4.


Based on Orbital's highly successful and flight-proven STAR-2 satellite bus, Telkom-2 features state-of-the-art communications satellite technology, and 24 C-band transponders. The new spacecraft replaced PT Telkom's on-orbit Palapa-B4 satellite, improve communications coverage across Indonesia, and allow PT Telkom to expand its coverage area into southeast Asia and the Indian subcontinent. Orbital also is supplementing Telkom's existing ground station, and extensive mission operations support. There are several postpones exist before Telkom-2 was launched. Three postpones happened on November 2005 because of technical problems with Ariane 5 launch vehicle. Other postpones happened during November 2004 until October 2005 with different problems including technical problem with Telkom-2. Orbital's contract with PT Telkom includes an optional order for another geostationary satellite.
