58 -- SUPPLY, EQUIPMENT AND MATERIAL-COMMUNICATION,DETECTION AND COHERENT RADIATION EQUIPMENT POC Marcia Rutledge, Contracting Officer, (703) 602-0660. COMMON HIGH-BAND DATA LINK SURFACE TERMINAL (CHBDL-ST) -- POTENTIAL SOURCES SOUGHT Synopsis No.20. The Navy will procure approximately nineteen Common High Bandwidth Data Link Shipboard Terminals. An FY-99 award is anticipated for four to six systems with options for 13 additional systems through FY-03. This is a follow-on effort to the development contract awarded in September 1991. There will be an UNCLASSIFIED pre-solicitation conference for all interested contractor personnel beginning at 0900 on 11 March 1997 at SPA, 2000 N. Beauregard Street, Alexandria VA. The meeting will be held in the first floor board room. No clearances will be necessary. A CHBDL/CDL reading room is being made available to all potential bidders. The qualification test plan will be released and made available in the CDL/CHBDL-ST document reading room (located at Adroit Systems, Inc, 209 Madison Street, Alexandria, VA 22314) and the SPAWAR electronic bulletin board (http://bbs.spawar.navy.mil) starting 17 March 1997. The CHBDL specification, the confidence/qualification test plan, and other government documents will only be available in the CHBDL/CDL reading room from 17 March to 17 April 1997 and for a one-month period when the RFP is released (currently 2 -- 30 June 1997). The CDL and CHBDL specifications will be releasable to US firms only. The overall goal of the CHBDL program is to produce and deploy a shipboard digital data link that is Common Data Link (CDL)-compatible to support air-to-surface transmission of imagery, video, and other sensor information. The Navy requires a wideband, microwave, shipboard digital data link capability to support new tactical reconnaissance systems, including the Battle Group Passive Horizon Extension System (BGPHES) and the Advanced/Tactical Air Reconnaissance System (ATARS)/Joint Services Imagery Processing system -- Navy (JSIPS-N). CHBDL-ST is a shipboard communications terminal that provides a line-of-sight, full-duplex, data communications link between shipboard signal processing equipment (e.g., BGPHES SURFACE Terminal or JSIPS-N Tactical Input Segment (TIS)) and remote reconnaissance aircraft, equipped with a Common Data Link Airborne (CDL A/B) System. The terminal operates in the X-band using offset QPSK and BPSK modulation. The CHBDL-ST receiver and transmitter are tunable in the operating frequency band. It transmits at a 200 kbps data rate (prior to error correction and spread spectrum encoding), and receives at variable data rates, including 10.71 Mbps, 137 Mbps and 274 Mbps. The system utilizes forward error correction coding and interleaving techniques and employs an encryption and decryption capability in accordance with the classified interface design specifications of the supported systems. The CHBDL-ST transmits digital commands for control of sensor equipment on the aircraft, data link control commands, and a voice link in accordance with CDL specifications. It receives digital sensor data from the aircraft, link status information, aircraft navigational data, rangingdata, and a voice link in accordance with CDL specifications. The CHBDL-ST connects with shipboard signal processing equipment via baseband data interfaces to provide mission data and receive sensor equipment commands. The CHBDL-ST utilizes two independent antenna systems with switching capability between them and sequentially supports interfaces to two separate shipboard signal processing systems located in different sections of the ship. The CHBDL-ST system compensates for ship's motion to maintain and stabilize antenna pointing angle. The command uplink has Low Probability of Intercept (LPI) characteristics based open parabolic antenna directivity, signal modulation format, and transmitter power output control. Electronic Counter Countermeasures (ECCM) are provided to ensure mission performance in a hostile ECM environment. All participating bidders should be able to incorporate pre-planned product improvements for adding Ku-band (GUARDRAIL) CDL capability, simultaneous multi-mission operations, ATM interface, and full wideband encryption. SPAWAR is looking for COTS/NDI CDL systems which can meet all CHBDL-ST specification requirements and pass Government confidence/qualification testing in January 1998. All firms interested and have the capability to develop and build, and install up to nineteen CHBDL-ST systems by the year 2003 with the first system to be fielded within fifteen months of contract award should provide a letter of intent to compete indicating your firm's commitment and capability to provide a candidate CHBDL-ST system to the test site for confidence/qualification testing by 14 January 1998. Your letter should also provide a written summary of your firms qualifications and capability to deliver a candidate system. Your qualification package should address how your candidate system will ensure interoperability with the Common Data Link Airborne (CDL A/B) systems currently in use throughout the U.S. military services. Areas of high risk should be identified along with technology availability forecasts and system cost. Interested firms should indicate whether they are Large Business, Small Business (SB), Small Disadvantaged Business (SDB), or 8(a). Potential bidders with ship-deployable systems will be required to deliver their systems to the Navy test site (currently planned to be in the Jacksonville FL area). Candidate systems will be required to pass the same tests that the currently-qualified system passed during developmental and operational testing. For questions about the Pre-Solicitation meeting please call Mr. Kurt Brantley, (703) 602-4387 or (703) 578-5698. Clearances will be necessary for contractor personnel to access the CHBDL/CDL reading room. Clearance messages should be submitted to visiting to reading room to Ms. Joyce Pool, Adroit Systems, Inc, 209 Madison Street, Alexandria, VA 22314, Fax (703) 836-7411, tel (703) 684-2517. This is not a RFP, potential offerors will not be paid for any effort in responding to this request. Closing date for the submission of the letters of intent isforty-five business days from the publication of this notice but no later than 30 April whichever comes first. Technical proposals will be required before qualification testing. Only firms determined to be in a competitive range will submit cost proposals. Respondees should send their submittal to Commander, Space and Naval Warfare Systems Command, Department of the Navy, 2451 crystal Drive, Arlington, VA 22245-5200, Attn: Ms Marcia Rutledge, Code 02-11A. Responses must reference this Synopsis No. 20. On both enclosures and the mailing envelope. (0049)
