  • Power beaming providing a space power infrastructure

    Publication Year: 1992, Page(s):7 - 11
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (657 KB)

    A study based on two levels of technology maturity, which applies to the power beaming concept to four planned satellite constellations, is described. The analysis shows that with currently available technology, power beaming can provide mass savings to constellations to orbits ranging from low-Earth orbit to geosynchronous orbit. Two constellations, a space surveillance and tracking system and sp... View full abstract»

  • Evaluation of nickel-hydrogen battery cells for space-based radar

    Publication Year: 1992, Page(s):37 - 42
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (552 KB)

    A study conducted in 1991 on nickel-hydrogen (NiH/sub 2/) battery cells, to assess their use for space-based radar satellites, is discussed. Current NiH/sub 2/ and related programs were investigated. Cell performance data were assessed, focusing on pulsed-load operation, cell design factors, and life expectancy. A need for pulsed-load testing of candidate cells, especially to characterize their ef... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1309 KB)

    Flight qualification of the multicell common pressure vessel (CPV) nickel-hydrogen (Ni-H/sub 2/) battery is discussed. The battery has completed full flight qualification, including random vibration at 19.5 g for two minutes in each axis, electrical characterization in a thermal vacuum chamber, and mass-spectroscopy vessel leak detection. A first launch is scheduled in 1992. Several design variati... View full abstract»
