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 November 16, 2005, and positioned in geosynchronous orbit, 22,300 miles above the Earth, at 118 degrees East longitude.
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 segment through the addition of a state-of-the-art ground station including all hardware and software. Orbital is also providing extensive mission operations support.
