Seventeen of these panels consist of silicon solar cells. The high-efficiency GaAs cells are used on the 18th panel due to area limitations. The EPS stores power in two batteries. Each battery consists of nine, commercial nickel-cadmium cells. Ground stations will need the capability to conduct spread spectrum communications.
Facilities are also in place for component and subsystem environmental testing.
The major testing facilities currently operable include a 500 pound shaker and a 1 cu. We also have an assortment of software tools for mechanical design and test, electronic design, thermal analysis and orbital mechanics.
