Mission Description
Orbital built the TELKOM-2 C-band satellite for Indonesia’s state-owned telecommunications company,
PT Telekomunikasi Indonesia Tbk (Telkom). The contract included the satellite, a state-of-the-art ground
station and turn-key on-orbit delivery. The satellite operates in geosynchronous orbit at 118 degrees
East Longitude. TELKOM-2 replaced the on-orbit Palapa-B4 satellite allowing Telkom to expand its
satellite communications coverage area into the southeast Asian region and the Indian subcontinent in
addition to Indonesia.
The GEOStar
™
Advantage
Orbital’s highly successful Geosynchronous Earth Orbit (GEO) communications satellites are based on
the company’s GEOStar spacecraft platform, which is able to accommodate all types of commercial
communications payloads and is compatible with all major commercial launchers. The company’s
GEOStar product line includes the GEOStar-2 design, which is optimized for smaller satellite missions
that can support up to 5.0 kilowatts of payload power. Orbital has also developed the higher-power
GEOStar-3 spacecraft design, delivering the next increment of payload power for applications between
5.0 and 8.0 kilowatts, allowing Orbital to offer its innovative and reliable satellite design to the
medium-class of communications satellites.
