Palapa is a series of communications satellites owned by Indosat, an Indonesian telecommunications company (formerly by Perumtel and then by PT Satelit Palapa Indonesia/Satelindo). The first satellite was launched in July 1976, at which time Indonesia became the first developing country to operate its own domestic satellite system.[1] The estimated cost for the project was US$1 billion (equivalent to $4.17 billion in 2023).[2][3]
