Telkom 4, also known asMerah Putih, is an Indonesian geostationary communication satellite built bySpace Systems/Loral that is located at an orbital position of 108° East and is operated byPT Telekomunikasi Indonesia Tbk. The satellite is based on theSSL 1300 satellite bus and has a life expectancy of 16 years. It was launched on 7 August 2018, at 05:18UTC or 12:18Jakarta Time, using theSpaceX Falcon 9 Block 5 launcher fromCape Canaveral Air Force Station, Florida, United States.[4][5]
This satellite carries 60 activetransponders consisting of 24 C-Band transponders and 12 Extended C-Band transponders which will serve theSoutheast Asia region, including Indonesia, as well as 24 C-Band transponders which will reach theSouth Asia region. The satellite relies on the SSL 1300 satellite bus with a design life of 16 years with up to 21 years of fuel remaining. The development of the Merah Putih Satellite involves two U.S. companies, namely SSL as a satellite manufacturer andSpaceX as alaunch service provider. The total mass of the satellite is 5,800 kilograms (12,800 lb). Telkom-4 is devoted to servinghigh-definition television (HDTV) broadcasts,GSM andInternet services.
Telkom-4 was launched using the SpaceXFalcon 9 Block 5 first stageB1046.2 from Cape Canaveral Air Force Station (CCAFS), Florida, United States on 7 August 2018, at 01:18 UTC. The launch was the first time SpaceX reused one of the Block 5 variant of the Falcon 9 rocket boosters.[6] After successfully separating from the second stage, the first stage landed on the SpaceX drone shipOf Course I Still Love You.
The launch of the Telkom-4 (Merah Putih) satellite saves around 25% of the cost of launching the previous satellite, theTelkom-3S satellite, which was launched on 15 February 2017, which cost US$215 million. Meanwhile, the Merah Putih satellite only costs US$165 million and includes insurance costs of US$10 million.[7]
Due to the inadequacy of thePalapa-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 to Telkom-4.[9] Below is a list of frequency of channels that have migrated as of July 2020:[10]
