Telkom-2 was 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 on 16 November 2005, at 23:46:00 UTC and positioned in geostationary orbit, at 118° East for replaced Palapa-B4.
The new spacecraft replaced PT Telkom's on-orbit Palapa-B4 satellite, improved communications coverage across Indonesia, and allowed PT Telkom to expand its coverage area into southeast Asia and the Indian subcontinent.
Orbital also supplemented Telkom's existing ground station, and offered extensive mission operations support.
Orbital's contract with PT Telkom included an optional order for another geostationary satellite.
