HTS-113BT is a new High Throughput Satellite telecommunications satellite in C-band/Ku-Band for PT Telkom Satelit Indonesia (Telkomsat) , a state-owned digital telecommunication company in Indonesia, for its orbital position at 113° East. Built on Thales Alenia Space's historical Spacebus 4000B2 platform, HTS 113BT will provide more than 32 Gbps capacity over Indonesia. The satellite will weigh about 4 metric tons at launch and will be delivered early 2024 for a 15-year expected lifetime.
