Telkom-3 is an Indonesian communications satellite which failed to reach its target orbit due to a launch failure on 6 August 2012. It was built by ISS Reshetnev for Indonesian telecommunications provider PT Telekomunikasi Indonesia. It was based on the Ekspress-1000H bus and had 32 C band transponders and 16 Ku-band transponders. It was due to be located in geosynchronous orbit at 118° East above the equator.[1][2] The satellite reentered the atmosphere and was destroyed on 5 February 2021.[4]
