, French Guiana, as the first direct broadcasting satellite (DBS) in Asia, IndoStar-1 would initiate a new communication service for Indonesian society such as direct-to-home television.

The IndoStar-1 spacecraft was originally designed and built by a team of engineers, who had up until the IndoStar program, focused on Low Earth Orbit (LEO) satellites for the US government and NASA, at Defense Systems Inc (DSI). DSI was under a 1993 joint contract, together with its sister company International Technologies Inc. (ITI), for the on-orbit turn-key delivery of Indostar-1 for the Indonesian television broadcasting company PT Media Citra Indostar (MCI). The contract, which included; launch, Tracking Telemetry & Control Station, Up-Link Station for 50 MPEG television channels, Integrated Receiver Decoder (IRD) design, ITU regulatory filings, insurance, and spacecraft - was the first fully turn key contract in the commercial satelltie industry for a satellite system.

In 1995 DSI was bought by Computer Technology Associates (CTA) to form their Space Systems division, and two years later sold to Orbital Sciences Corporation

IndoStar-1 was the world's first commercial communications satellite that uses S-band frequency, which are less vulnerable to atmospheric interference than higher and more common frequencies of C-band and Ku-band frequencies. Provided high-quality transmissions to small-diameter antennas (70 cm) and penetrated the atmosphere efficiently, this satellite is well suited for Indonesia, the tropical climate country that has heavy rain. This satellite, which is managed and operated by PT Media Citra Indostar (MCI), provides a direct broadcast by high quality digital transmission. Operationally, IndoStar-1 satellite is used for commercial service by cable television
