Summary

The USA 325 satellite, also known as GeoStar-1, was launched on January 21, 2022, from Cape Canaveral Air Force Station's SLC41 launch pad using the Atlas V 511 launch vehicle. This US-owned satellite is operated by the U.S. Space Force (USSF) for space surveillance purposes and has a mission lifetime of six years. The spacecraft measures 2 meters in length, with a diameter of 2 meters and spans 5 meters when its solar arrays are deployed. It weighs 500 kilograms at launch and maintains the same dry mass. Its shape is described as box-like with two panels. Power for the satellite is provided by two deployable solar arrays and batteries. The satellite's equipment includes Hornet 6 payload for its mission operations, supported by attitude control systems (AOCS) manufactured by NGISD.
