58 -- COMMERCIAL/GOVERNMENT OFF-THE-SHELF (LOTS/GOTS), NON- DEVELOPMENTAL ITEM (NDI) SUBMARINE HIGH DATA RATE (HDR) SATELLITE COMMUNICATIONS (SATCOM) SYSTEM AND/OR COMPONENTS POC Dea Merchant, 02-33, 703-602-0640. Synopsis no. 9. The Space and Naval Warfare Systems Command (SPAWAR) is seeking information on potential sources of EHF (LDR and MDR), SHF DSCS, and Ku-Band (hereinafter referred to as multi-band) or EHF (LDR and MDR) and SHF DSCS (hereinafter referred to as dual-band) COTS/GOTS, NDI Submarine HDR SATCOM System and/or components. A system is to be comprised of: (1) inboard SATCOM equipment that may perform such functions as user input/output, modulation/demodulation, frequency synthesis, and signal processing; (2) an antenna controller to provide antenna pointing and tracking of multiple outboard antennas; (3) an outboard antenna mast with a multi-band or dual-band antenna (including any required radome) and a pressure-proof enclosure which may contain electronics for upconversion, amplification, and transmission on the transmit side and reception, amplification, and downconversion on the receive side; (4) a mast mechanical group to provide the physical interface between the antenna mast and the submarine. (This system functional allocation is not intended to limit the proposal of alternative systems functional allocations. For example, the upconversion function may be allocated to the inboard SATCOM equipment vice the outboard antenna mast electronics if desired.) The systems or component must be capable of operating in the submarine underwater environment with associated environmental, reliability, and maintainability characteristics. In addition, the system or component must use V'u/Z)~))Y{)hx9chitecture (OSA) to the maximum extent possible. The inboard SATCOM equipment must support real-time selectable, full duplex communications at all standard EHF (LDR and MDR), SHF DSCS, and (for multi-band) Ku-Band data rates up to and including 1.544 Mbps (for growth purposes). The antenna controller must be OSA based and must interface with the inboard SATCOM equipment and the outboard antennna mast electronics. The HDR multi-band or dual-band antenna mast with closure door must fit within the existing SSN AN/BRA-34 and/or AN/BRD-7/BLD-1 antenna bays. The HDR antenna and mast electronics must support full duplex multi-band or dual-band operation on a real-time selectable or mission configurable basis. The antenna and mast electronics are not, however, required to operate at more than one frequency simultaneously. The HDR dual-band antenna and mast electronics must provide suffcient performance to support: (1) a minimum EHF MDR data rate of 128 kbps (assuming a distributed user coverage area (DUCA) antenna and no more than 17% of satellite downlink capacity); and (2) a minimum SHF DSCS data rate of 128 to 256 kbps (assuming a multi-beam antenna and 40% of a 40 watt transponder). In addition, the multi-band antenna and mast electronics must provide sufficient performance to support a minimum Ku-band data rate of 256 kbps (assuming a spot beam and 10% of the transponder) assuming standard weather margins. Information on a related Government systems and its components may be made available upon request. If potential sources exist, the performance requirements of the Submarine HDR SATCOM system will be throughly documented in a draft performance specification and released to industry for review and comment. Ultimately, an RFP to procure a Submarine HDR SATCOM System may be released. Potential sources are invited to provide information on either an entire systems model or systems components they can provide, how these componets fit within an overall system, and system integration recommendations. Models and/or components should be fully functional and may be requested for Government demonstration/testing pending release of a Submarine HDR SATCOM System RFP at no cost to the Government. Responses to this sources sought synopsis must include brochures, drawings, and other substantive information demonstrating the contractor's ability to provide the aforementioned Submarine HDR SATCOM System models or components. In addition, responses must include the following information on the models and/or components (as applicable): a brief system overview; a functional diagram; critical performance parameters (e.g., Effective Isotropic Radiated Power (EIRP) and receive (G/T) at all operating frequency bands); lead time for delivery of no-cost model/components in months after receipt of order; estimated production lead time in months after receipt of order; single unit production cost estimate and anticipated learning curve; and recommended logistics concept to include sparing requirements, training concept, and maintenance concept. This is not a request for proposals nor does the Government intend to pay for any informtion solicited. Proprietary data submitted in response to this synopsis will be protected when clearly indentified as such. Acknowledgement of receipt will not be made, nor will telephone inquiries be honored. Interested firms must indicate whether they are Large Business, Small Business, Small Disadvantaged Business or 8(a) Set-side. Responses to this sysnopsis must be received no later than 25 February 1995. Firms must submit six (6) copies of qualifications packages. Responses to this synopsis must be in writing to Commander, Space and Naval Warfare Systems Command Attn: Dea Merchant/02-33Z, 2451 Crystal Drive, Arlington, VA 22245-5200. Responses must refer to this synopsis on both mailing envelopes and enclosures. (0025)
