Telkom-2 is a C-band geosynchronous communications satellite built by Orbital for Indonesia's state-owned telecommunications company, PT Telekomunikasi Indonesia Tbk (PT Telkom). TELKOM-2 was successfully launched 16 November 2005, and positioned in geosynchronous orbit, 22,300 miles above the Earth, at 118°E (0°N 118°E / 0°N 118°E / 0; 118Coordinates: 0°N 118°E / 0°N 118°E / 0; 118).


Based on Orbital's highly successful and flight-proven STAR-2 spacecraft platform, TELKOM-2 features state-of-the-art communications satellite technology, and 24 C-band transponders. The new spacecraft will replace 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.

In addition to providing the spacecraft bus and payload, Orbital is supplementing Telkom's existing ground station through the addition of a state-of-the-art ground station including all hardware and software. Orbital is also providing 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 rocket. 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 geosynchronous satellite.
