The GEOStar-3 is a communications satellite spacecraft model made by Northrop Grumman Innovation Systems.
GEOStar-3 represents an evolutionary growth from Northrop Grumman Innovation Systems GEOStar-2 platform.
The GEOStar-3 Bus can accommodate payloads of up to 800 kilograms and 8,000 watts.
[1] Some changes to the GEOStar-3 bus include increased battery capacity and solar array power, enabling it to provide up to eight kilowatts of power to the payload.
In addition to increased payload power, GEOStar-3 also has the option of utilizing electric propulsion, which allows it to complete its fifteen to seventeen year mission life with less fuel.
