STAR Bus is a satellite platform manufactured by Orbital Sciences Corporation with an apogee kick motor to place a communications satellite into geostationary orbit, a thruster to provide the satellite with orbital station-keeping for a 15 year mission, and solar arrays to provide the satellite payload with 5 kW[citation needed] of electrical power.

Also see STAR-2.


The first satellite based on the STAR Bus platform was IndoStar-1, which was launched in November 1997.[citation needed]
