E-MAIL: rutledgm@nosc.mil, rutledgm@nosc.mil. Supply, Equipment and Material Communication, Detection, and Coherent Radiation Equipment Synopsis # -- Revision of orginal submission No. 12033 SPACE AND NAVAL WARFARE SYSTEMS COMMAND; 53560Hull Street, OT#4, San Diego, CA 92152-5002 58 -- COMMON HIGH-BAND DATA LINK SURFACE TERMINAL (CHBDL-ST) POC Ms. Marcia Rutledge, 02-11A (619) 524-2829. 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. These systems will be installed on CV/CVN, LHA, LHD, LCC, and AGF class ships. This is a follow-on effort to the development contract awarded in September 1991. 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, ranging data, 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. The Navy will have procured nine CHBDL-ST systems through FY 98. SPAWAR is looking for COTS/NDI CDL systems which can meet all CHBDL-ST specification requirements and pass Government confidence/qualification testing which will be held 15 February to 1 April 1998. 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. Clearances will be necessary for contractor personnel to access the CHBDL/CDL reading room. Clearance messages should be submitted to visit the reading room to Ms. Susan Shriver or John Cummings, Adroit Systems, Inc, 209 Madison Street, Alexandria, VA 22314, Fax (703) 836-7411, tel (703) 684-2900, or via the Internet at read_ chbdl@alexandria.adroit.com... A CHBDL/CDL reading room is being made available to all potential bidders to assure that each vendor has equal access to the technical documents owned by the government. Equal bidder access will be documented; appointment books, visitor logs and security clearance will be retained on file. All documents, i.e. specification, ICDs, Standards, Handbooks, DOD manuals, TMCRs and classified documents will be made available in the CDL/CHBDL-ST document reading room (located at Adroit Systems, Inc, 209 Madison Street, Alexandria, VA 22314 . The reading room will be available by October 10, 1997. The CDL and CHBDL specifications will be releasable to US firms only. An updated draft RFP will be released on the Internet at the URL "http://raven.spawar.navy.mil" on 9/15/97, comments are due by 9/24/97. The official RFP will be released on the Internet on 10/10/97. The official closing date is November 14, 1997. Respondees should send their submittal to Commander, Space and Naval Warfare Systems Command, Department of the Navy, 53560 Hull Street, OT4, San Diego, CA 92152-5002, Attn: Ms Marcia Rutledge, Code 02-11A. Responses must reference this Synopsis/ notice No. on both enclosures and the mailing envelope. Companies interested in subcontracting opportunities should notify 02-11A in writing and their letters and/or prospectus will be forwarded to all companies submitting bids. No bidders list will be available. (0255)
