  • Publication number: 20150236398
    Abstract: A rotationally-stabilizing tracking antenna system includes a three-axis pedestal, a drive assembly rotating a vertical support assembly relative to a base assembly, a cross-level driver pivoting a cross-level frame assembly relative to the vertical support assembly, and an elevation driver pivoting an elevation frame assembly relative to the cross-level frame assembly, a motion platform assembly affixed to the elevation frame assembly, three orthogonally mounted angular rate sensors disposed on the motion platform assembly sensing motion about X, Y and Z axes, a three-axis gravity accelerometer mounted on the motion platform assembly to determine a true-gravity zero reference, and a control unit determining the actual position of elevation frame assembly based upon sensed motion about X, Y, and Z axes and the true-gravity zero reference, and controlling the azimuth, cross-level and elevation drivers to position the elevation frame assembly in a desired position.

  • Publication number: 20150222024
    Abstract: A tracking antenna system for discrete radio frequency spectrums includes a reflector, a pedestal supporting the reflector, a radome assembly enclosing both, a first feed for gathering radio waves within a first of discrete RF spectrums that is removably disposed in front of the reflector at the focal point, a first RF module operably connected to the first feed for converting the first gathered radio waves to first electronic signals, a feed mount for removably supporting the first feed and configured to removably support a second feed for gathering radio waves within a second of discrete RF spectrums, and a module mount for removably supporting the first RF module and configured to removably support a second RF module for converting the second radio waves to second electronic signals. A method of using the tracking antenna system adaptable for discrete radio frequency spectrums is also disclosed.

  • Publication number: 20100295749
    Abstract: A radome for a tracking antenna system may include a dome for covering the tracking antenna, wherein the dome includes a dome wall having inner and outer skins sandwiching a low dielectric material layer therebetween, and wherein the dome wall includes a gel coat layer covering the outer skin to protect the dome in a marine environment. The inner and outer skins may have a thicknesses of approximately 0.007 to 0.027 inches, more preferably approximately 0.014 to 0.020 inches, and most preferably 0.017 inches. The low dielectric material layer may have a thickness of approximately 0.153 to 0.173 inches, more preferably approximately 0.160 to 0.166 inches, and most preferably 0.163 inches. The gel coat may have a thickness of approximately 0.010 to 0.030 inches, more preferably approximately 0.017 to 0.023 inches, and most preferably 0.020 inches. The tracking antenna system may include a tracking antenna having a resonant frequency of approximately 3 Hz to 5 Hz.
