GPM's Solar Array Wings in Testing JacobAdmin Tue, 10/18/2011
(ambient audio only) 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. GPM's two solar array wings that extend to the right (+Y) and left (-Y) of the spacecraft are currently undergoing assembly and testing at Goddard

The –Y wing undergoes modal testing, a type of vibrational testing.

The small squares are 59 accelerometers that measure the movement of the array.

High Gain Antenna System (HGAS) Completes Deployment Testing

The High Gain Antenna System (HGAS) onboard the GPM Core Observatory finished acoustics and post-environmental deployment testing at NASA Goddard Space Flight Center. The HGAS will then undergo Thermal Vacuum testing before it is completed and delivered in mid-September. The below video shows a test of the High Gain Antenna System as it will deploy once in orbit aboard the GPM Core Observatory. Learn more about the HGAS and the GPM Core Observatory
