This and other similar tests will verify the deployment function of the GPM Core Observatory solar arrays in ambient condition. Data such as deployment time, hinge forces, and system stiffness will be gathered and reviewed for requirement compliance. The qualification unit was assembled with flight and non-flight components. The flight components will be removed and integrated with the flight unit after qualification testing.
