  • Journal of Spacecraft and Rockets > Deployment of dishes with surface discontinuities
    For compatibility with the relevant parts of Ref. 36, consider the dish with representative dimensions for multipurpose small satellite applications: a D = 120 in. = 3.048 m diam and focal length F = D. Let the antenna 's constitutive shell be a midsurface … … petals, take a honeycomb coreun- der a laminate face sheet yielding a 1.5- cm total thickness.
  • Global Mobile Satellite Communications
    The antenna is available with diameter of 65, 98, 120 , 180 and 240 cm dishes depending on position in coverage area and distance from subsatellite point. Mobile satellite users can also be included in this category of satellite communications.
  • INTERSPUTNIK's development prospects on the eve of the XXIst century
    LMI-KA satellite system earth stations (ultra small antenna terminal). Depending on the transmission rate, the dish diameter will range from 60 to 120 cm with transmitters of 0.25 to 1OW.
  • Multimedia satellite communications
    The system uses Ka-band satellites and sub-meter size antennasto deliver service. The ASTRA Return Channel System will offer the combi- nation of Ku-band reception, at speeds up to 38 Mbps, with a Ka-band return channel, at speeds up to 150 kbps (on antenna as small as 60 cm ). Higher user data rates of up to 2 Mbps and beyond can be achieved through larger 120 cm dishes .
  • Consumer electronics
    Until recently in the United States, only Primestar Partners, an entertainment ser- vice, competed with DSS in the digital sat- elliterealm, using a medium-power satellite and 90- cm antennas , much larger than the pizza-sized type needed for DSS. … Colo., launched two high- powered digital broadcasting satellites (DBSs)designed to reach 46-cm (18 inch) dishes . … Stamford, Conn., launched a medium-powered DBS service designed to reach 30-inch dishes with 120 channels.

    … in Westford, Massachusetts [38] with the new system designated the Haystack Ultra-wideband Satellite Imaging Radar (HUSIR). The combination of increased operating frequency and replacement of the previous 37 m ( 120 ft) antenna with a new dish , accurate to 0.1 mm (0.004 in) over its entire surface is predicted to provide an order of magnitude increase in … … mm diameter antenna (beam divergence of ∼0.8◦, a range resolution of 50 cm is achieved at …
  • Implementation of wireless Internet access with elements of asymmetry
    Such system requires a standard satellite dish together with DVB card - a PCI board or external DVB equipment, which carries out digital signal processing coming from receiving antenna and converts it into a videostream, or internet data. With this coverage it is enough to have antenna with diameter of 60 cm . But for better performance the E3IKT department decided to place antenna with diameter of 120 cm.
  • Sea surface scattering calculations in maritime satellite communications
    The C / S and CIM ratios are calculated versus various parameters describing the sea state, the wind and the elevation angle, for different types of antennas (short backfire, helical, hemispherical, parabolic dish ). So for comparison purposes it is somewhat arbitrarily assumed that these sea states correspond to wind friction velocities 11, of 20, 70 and 120 cm /s, Le., wind velocities measured at 19.5 m height of 6.5, 16.5 and 24 … … started in 1984 by the European Space Agency (ESA), directed towards defining future satellite -mobile communications systems.
