Very Low Frequency (VLF) Transducer Navy SBIR FY2010.3 Sol No.: Navy SBIR FY2010.3 Topic No.: N103-223 Topic Title: Very Low Frequency (VLF) Transducer Proposal No.: N103-223-0170 Firm: Progeny Systems Corporation 9500 Innovation Drive Manassas, Virginia 20110 Contact: Dave Baird Phone: (801) 359-4566 Web Site: www.progeny.net Abstract: The Acoustic augmentation Support Project (AASP) provides a temporary system that is used to produce acoustic signals across an operating band of 10Hz to 44kHz. These signals are used by the Navy for team training exercises in anti-submarine warfare (ASW). The AASP system, as it is currently configured, consists of a drive computer, 2 power amplifiers, and 3 transducers. One of the transducers supports the VLF frequency spectrum, one supports the LF to MF frequency spectrum, and the last supports the HF frequency spectrum. The problem with the AASP system lies primarily with the HLF-1 transducer that supports the system's VLF frequency band. The transducer options currently available to the Navy to support the VLF spectrum of AASP all have limitations such as external compensation, excessively large size, high power draw, etc. Benefits: This technology has possible use for offshore oil exploration.
