Figure 7.10 Schematic of Space Station Freedom Proposed SDS [Dustin,1992] Figure 7.11 The SDS for Space Station Freedom [Dustin,1992] Small Satellites If we can provide small satellites (communications, Earth observing) with Solar Dynamic System (SDS) - these satellites will have a longer lifetime and also lower amortized costs. SDS is less susceptible to radiation effects then photovoltaic panels and that translates into long term life and operational flexibility. At the present moment SDS are too heavy for small satellites, and it is necessary to also develop a high efficiency, low mass auto-deployable concentrator.
