Starbus-C
American communications satellite bus. The Orbital Star bus was designed for reliable and robust performance in a variety of LEO and GEO missions.

AKA: Indostar;Mexsat;Orbital Star;Star-2 bus. Status: Operational 1997. First Launch: 1997-11-12. Last Launch: 2015-05-27. Number: 34 . Gross mass: 1,620 kg (3,570 lb).

Orbital's turn-key approach included the GEO satellite, launch services, ground stations, user systems and business support. The STAR GEO platform was designed for a 15-year mission life. STAR GEO Payload options included: C-, Ku-, Ka-, S-, Hybrid-band frequencies; payload power from 500 to 4,500 W; up to 42 transponders; shaped beams or spots with up to two deployable and one deck-mounted antenna systems.

Orbital's Star 1 bus and had a launch mass of 1298 kg. It carried a Thiokol Star 30 solid apogee motor and a set of station-keeping thrusters with 200 kg of propellant. The improved Star 2 satellite bus had a dry mass around 800 kg . It used an Orbital hydrazine/nitrogen tetroxide liquid apogee propulsion system with a 500N thrust apogee engine developed by Japan's IHI.

The Orbital Star bus was a flight-proven design that could deliver reliable and robust performance for a variety of LEO and GEO missions. Orbital's turn-key approach included the GEO satellite, launch services, ground stations, user systems and business support. The STAR GEO platform was designed for a 15-year mission life. STAR GEO Payload options included: C-, Ku-, Ka-, S-, Hybrid-band frequencies; payload power from 500 to 4,500 W; up to 42 transponders; shaped beams or spots with up to two deployable and one deck-mounted antenna systems.

A new era for Orbital began in November 1997 when its first GEO satellite, IndoStar-1, was launched aboard an Ariane 4 rocket from Kourou, French Guiana. Orbital built the IndoStar-1 satellite for Media Citra Indovision to deliver the first direct-to-home (DTH) satellite television to Indonesia, the world's fourth most populous county.

IndoStar-1 was the world's first commercial communications satellite to use S-band frequencies, which efficiently penetrated the atmosphere and provided high-quality transmissions to small-diameter antennas in regions that experience heavy rainfall such as Indonesia. Similar performance was not economically feasible with comparable Ku- or C-band DTH satellite systems since more power was required in these bands to penetrate the moist atmosphere.

Under the $175 million contract, Orbital served as the prime contractor for the turn-key system, including the space, ground and user segments. Specifically, Orbital provided:

In early 2001, Orbital firmly established itself as a major U.S. GEO satellite supplier with a contract from PanAmSat Corporation, which owned and operated one of the world's largest private fleets of commercial GEO communications satellites. Orbital was selected to supply one C-band GEO satellite designated Galaxy XII to be located at 72 deg W longitude. In late 2001 PanAmSat exercised an option for two additional C-band spacecraft. The satellites were to distribute entertainment and information to cable television systems, TV broadcast affiliates, direct-to-home TV operators, Internet service providers, telecommunications companies and corporations.

Characteristics of this version of the Star bus were:
