- Description
- The Naval Undersea Warfare Center Division Keyport (NUWC Division Keyport) is soliciting proposals under a Broad Agency Announcement (BAA), N00253-06-T-0145. NUWC Division Keyport is interested in proposals that identify Multi-Frequency Underwater Tracking Transducers that will be able to transmit and receive multiple frequencies in an undersea environment. For first round consideration, proposals in response to this BAA shall be received by 15 June 2006, 1500 hours Pacific Time, addressed to Naval Undersea Warfare Center Division Keyport, Acquisition Division, 610 Dowell Street, Keyport WA 98345, Attn: Ms. Monique Klose. For second round consideration, proposals in response to this BAA shall be received by 14 July 2006, 1500 hours Pacific Time. For third round consideration, proposals in response to this BAA shall be received by 15 Aug 2006, 1500 hours Pacific Time. This is an unrestricted solicitation. The purpose of this announcement is to investigate innovative! commercial technologies and approaches to transmit and receive multiple frequencies underwater using underwater tracking transducers. In addition, the Navy is seeking to establish a broad base of capable and knowledgeable contractors that may compete for future contracts involving transmission and receipt of multiple frequencies using underwater tracking transducers. Under this broad agency announcement, contracts will be awarded to those contractors who are determined technically acceptable. Proposals must include the following: A technical proposal consisting of no more than five 8 inch x 11 inch pages that details how its technology may be used in the transmission of data and telemetry between a submarine and a fixed platform using acoustic modems. Commercial product brochures may be provided as supplementary information. The technical proposal will be reviewed and evaluated for technical acceptability. Elements considered in determining technical acceptability will be realism and innovation of approach, with an emphasis on the ability for receipt of multiple frequencies underwater. Sources are sought for the design, development, testing and evaluation of an underwater tracking transducer. The transducer would be able to transmit and receive multiple frequencies. It is anticipated that testing will be accomplished by the Government, specifically NUWC Keyport and NSWC Carderock. However, past test reports of demonstrated technical ability are encouraged but not required. Following are desired technical characteristics: Operating Frequencies: The proposed multi-frequency underwater tracking transducer would be used to transmit (i.e., project) the following operating frequency ranges and frequencies: 12.9 kHz, 13.5 kHz, 75 kHz and 96 kHz. It is desired that additional transmit frequencies include 17.2 kHz and 37 kHz. The transducer would be used to receive the following operating frequency range: 16 kHz to 21 kHz. Bandwidth: The transducer will have a 3 kHz bandwidth centered at the operating frequencies for 12.9 kHz and 13.5 kHz, and an 8 kHz bandwidth centered at the operating frequencies for 75 kHz and 96 kHz. Additional desired operating frequencies of 17.2 kHz and 37 kHz will have 3.5 kHz and 5 kHz bandwidths centered at the desired operating frequencies, respectively. Transmit Voltage Response: The transmitting constant voltage response will be flat within + or - 3 dB within bandwidths and frequency ranges. It is desired this response be flat within + or - 2 dB. Directivity Beam Patterns: The transmitting directivity response will be a hemi-spherical pattern. The beam pattern for lower frequencies (i.e., 12.9 kHz, 13.5 kHz, 17.2 kHz, and 37 kHz) will not be down more than 10 dB + or - 30 degrees from a zero degree centerline, with zero degrees pointing to the ocean floor. Higher frequencies (i.e., 75 kHz and 96 kHz) will not be down more than 10 dB + or - 30 degrees from a + or - 90 degree centerline, with zero degrees pointing to the ocean floor (i.e.,! side projection). Receive Sensitivity and Pattern: A minimum sensit ivity of -198 dBv/uPa over the entire receiving operating frequency range (16 kHz to 21 kHz). Depth capability: The depth capability shall be at least 3,000 feet (914 meters), 0 to 1320 psig. Depth Sensor: A depth sensor will be incorporated into the transducer. A voltage regulated depth sensor using 1 mV equivalent to 1.000 FT of seawater is required. The supply voltage for the depth sensor will be 26 VDC ? 5 percent, and the output voltage shall be isolated. A drift rate of less than 30 mV over the life of the depth sensor is required, which suggests micro-electro-mechanical systems (MEMS) technology used with piezoresistive silicon that is micro-machined. Initial tests by the U.S. Navy have proven this type of sensor produces extremely high levels of stability and repeatability across the entire pressure range. Weight: The maximum dry weight will be less than 25 lbs (11 kg mass). Size, Shape and Mounting: The free stream drag force on the transducer at 25 knots is ~800 lbs, and the dynamic load profile needs to be minimized. Provide the minimum envelope and shape of the proposed transducer. Various mounting plates and brackets are intended for use, although the initial mounting plate for the transducer can be adjusted to allow for part of the transducer to be recessed within the ship?s structure. Connectivity: It is desired the proposed transducer connects to existing cabling. Most existing underwater tracking system configurations use a 4-conductor cable, only 3 conductors are used for signals and the 4th conductor isn?t used since the shield is connected through the 4th pin of the 4-pin mating connectors. One frequently used underwater tracking system configuration has the capability and existing cabling of 7-conductor cable, only 6 conductors are used for signals and the 7th conductor isn?t used since the shield is connected through the 7th pin of the 7-pin mating connectors. Sound Pressure Level (SPL): The transducer will transmit an acoustic signal at a minimum SPL of 192 dB/uPa + or - 1.5 dB at 1 meter over a temperature range of 2 to 30 degrees C, and over a hydrostatic pressure range of 5 psig to 1320 psig. In-Air Operation: The transducer will be capable of being driven in-air for four hours at an operational duty cycle of two pulses per second, with each pulse having a duration of 50 ms, + or - 5 ms. Input Power: The maximum input power level will be less than 225 Wrms in the operating band of frequencies. Input Impedance: The tuned input impedance of the transducer shall be optional to the extent that the resistive component value may be designed to meet one of the following three design constraints: 20 + or - 5 ohms, 50 + or - 5 ohms, 125 + or - 10 ohms or 200 + or - 15 ohms, with a desired reactive component that will cause a maximum phase angle deviation of 20 degrees over the operating frequency. Similar Equipment: The salient performance characteristics of ITC-1147 underwater tracking transducer are a good reference for the transmitted! 75 kHz operating frequency, and receive operating frequency range 16 kHz to 21 kHz. Submit pricing information separately, with unit and extended pricing information provided for a test unit of up to 2 each multi frequency underwater tracking transducers. NUWC Division Keyport anticipates awarding up to a maximum of $50K in awards, issued on a firm fixed price, bilateral purchase order basis. Proposals may be accepted, and awards made resulting from this announcement, through 26 May 2007. No minimum or maximum number of awards can be guaranteed.
