Chilled chips: smaller is better in satellite terminals.A digital technology that has been developed by Hypres Inc. of Elmsford, N.Y., for the project manager of Defense Communications and Army Transmission Systems, promises to substantially trim the foot print of ground-based satellite stations.Besides chopping the size of 60-foot parabolic par·a·bol·ic also par·a·bol·i·cal adj. 1. Of or similar to a parable. 2. Of or having the form of a parabola or paraboloid. dish antennas, the new X-band all digital receivers are expected to "slash the cost of acquiring a military satellite terminal in half from about $5 million to $2.5 million. by elminating up to seven racks of analog equioment and one 40-foot trailer," says Steonen Larsen. a PM DCATS PM DCATS Project Manager Defense Communications and Army Transmission Systems spokesman. The key to the more compact system is a niobium niobium (nīō`bēəm), metallic chemical element; symbol Nb; at. no. 41; at. wt. 92.9064; m.p. about 2,468°C;; b.p. 4,742°C;; sp. gr. 8.57 at 20°C;; valence +2, +3, +4, or +5. chip that becomes a superconductor A material that has little resistance to the flow of electricity. Traditional superconductors operate at absolute zero (-459.67 degrees Fahrenheit or -273.15 degrees Celsius). Experiments in the 1980s raised the temperature to -321 degrees Fahrenheit. when chilled to nearly absolute zero. |
