  • 99-0562D Thompson
    As such, the submarine must expose an antenna of some type and size while operating at depth Submarines are equipped with buoyant cable antennas (BCAs) that provide lim-ited, receive-only communications at depth, but are not capable of UHF or higher-frequency two-way communications
  • Buoyant Cable Antenna System and Method With Articulating Blocks
    flexible antenna system is operable for use in water with a transmission line The system comprises elements such as, for instance, articulating blocks that form a linear platform for towing in the water with the transmission line
  • FLOATING WIRE ANTENNAS COMMUNICATING WITH A SUBMERGED SUBMARINE
    The first fleet ballistic missile submarine, USS GEORGE WASHINGTON (SSBN 598), successfully used a fixed length outboard connected type buoyant cable antenna during an early patrol (1960) and reliably received VLF broadcasts while remaining completely submerged
  • Communication Antenna: A Key System of Modern Submarines
    The second option is to tow a Buoyant Wire Antenna which is a floating cable of several hundred meters long, a part of it being at the sea surface and able to receive VLF and HF frequencies
  • (20. 2 SBIR) Navy - Radio Frequency Buoyant Cable Antenna . . . - Navy SBIR
    OBJECTIVE: Develop a Buoyant Cable Antenna (BCA) handling transfer mechanism that can provide sufficient pushing and pulling force to cabled antennas at depth while limiting wear and stress to the cable
  • US5606329A - Buoyant cable antenna - Google Patents
    It has been proposed to maintain radio reception from a submerged submarine through a buoyant cable antenna ("BCA") which rises above the submarine and floats and streams at the ocean
  • Buoyant Wire Antenna Systems for Submarines
    These systems include a buoyant wire antenna, deployment system, and antenna coupler The antenna can be deployed and retrieved at various speeds and depths, allowing submarines to communicate below periscope depth without risk of detection
  • buoyant wire antenna, wire antenna submarine - NEREIDES
    The NEREIDES buoyant wire antenna, inboard or outboard according to the Navy requirements, is a turnkey system comprising a mechanical assembly for the deployment of the antenna and an electrical radio assembly ensuring the reception and transmission of data to onboard receivers
  • Global Positioning System over Fiber for Buoyant Cable Antennas - JHUAPL
    uoyant cable antennas (BCAs) are long, towed antennas used by submarines to receive RF signals Deployed while the sub-marine is operating at depth, the cable is managed so that the internal antenna element or elements are positioned near the ocean surface
  • Buoyant Cable Antenna Technology for Enhancing Submarine Communications . . .
    A major issue description of the DARPA Buoyant Cable Antenna with the floating antenna array concept is the exposure Array (BCAA) Program and APL’s role in it or washover characteristics of the array as it is towed along the sea surface by the submarine
