Telkom 4 also known as Merah Putih, is an Indonesian geostationary communication satellite built by Space Systems / Loral that is located at an orbital position of 108.0°E and is operated by PT Telekomunikasi Indonesia. This satellite is based on the SSL 1300 platform and has a life expectancy of 16 years, this satellite was launched on August 7, 2018 at 01.18 UTC or 12.18 Jakarta Time, using the SpaceX Falcon 9 Block 5 launcher rocket from Cape Canaveral Air Force Station Orlando, Florida, United States.[4][5]
Description
This satellite carries 60 active transponders consisting of 24 C-Band transponders and 12 Extended C-Band transponders which will serve the Southeast Asia region, including Indonesia, as well as 24 C-Band transponders which will reach the South Asia region .The satellite relies on the SSL 1300 platform with a design life of 16 years with up to 21 years of fuel remaining. The development of the Merah Putih Satellite involves two US companies, namely SSL as a satellite manufacturer and SpaceX as a satellite launch service provider. The total mass of the satellite is 5.8 tons. Telkom-4 is devoted to serving high-quality television broadcasts (High Definition Television) and GSM and Internet communication services
Launching
Telkom-4 satellite was launched using SpaceX Falcon 9 Block 5 booster rocket from Cape Canaveral Air Force Station, Orlando, Florida, United States on August 7, 2018 at 01.18 local time. The launch of the Telkom-4 satellite marks the first time SpaceX has reused one of the Block 5 variant of the Falcon 9 rocket boosters,[6] Block 5 is the last variant of the Falcon 9 that the CEO, Elon Musk, hopes to go back and forth in space up to 10 times. without significant improvement. Previous versions of this rocket were only capable of flying into space twice. After successfully making a flight, Falcon 9 landed on one of SpaceX drone ships, Of Course I Still Love You.
Launch fee
The launch of the Telkom-4 (Merah Putih) Satellite saves around 25 percent of the cost of launching the previous satellite, the Telkom-3S Satellite, which was launched on February 15, 2017 which cost US$215 million. Meanwhile, the Red and White Satellite launch project only costs US$165 million and includes insurance costs of US$10 million.[7]
Service users
Due to the inadequacy of the Palapa D satellite to operate until July 2020, while the replacement satellite, Nusantara Dua (Palapa N1),[8] failed to reach orbit, many TV and radio channels migrated from Palapa D [9] to Telkom-4. Below is a list of frequency of channels that have migrated as of July 2020:[10]
