The HS 702 is an innovative new line of high power, geosynchronous, communication satellites. The solar arrays use high efficiency gallium arsendide cells, and can be configured to generate up to 15 kW at end-of-life. A new feature on the HS 702 is angled solar reflector panels along both sides of the wings that form a trough and concentrate the sun's rays on the solar cells. Calculations using NASCAP/GEO, show that under non-eclipse conditions, photo electron emission from these solar reflectors will prevent spacecraft charging even during the most severe magnetospheric substorm. A surprising result is that even during eclipse, the reflectors will limit differential charging on the solar array to less than 16% of the overall satellite potential. This limiting occurs because the reflectors set up potential barriers that suppress secondary electron emission from the solar cell coverglasses. The result is that this type of reflector concentrator both helps array performance and controls spacecraft charging.
