A -- NAVIGATION AND LANDING ANALYTICAL, MODELING, TECHNICAL/ENGINEERING SUPPORT SERVICES DUE 042695 POC Jim Ammons, 202/267-3592 Pursuant to FAR 6.302-3, Industrial Mobilization; or engineering, developmental, or research capability, the Federal Aviation Administration (FAA) intends to procure, on an urgent sole source basis from Ohio University, Avionics Engineering Center, Stocker Center, Athens, Ohio, for the continuation services to provide analytical, mathematical modeling and technical/engineering support under a cost-type contract for approximately 15 man years over a five-year period starting September 25, 1995. In addition to being the incumbent on the current effort, Ohio University has extensive facilities and equipment including airport facilities and several aircraft outfitted with special instruments for testing of landing and navigation systems. The contractor shall provide, but is not limited to, support for the following National Airspace System (NAS) subsystems and related requirements: Support the Government in its activities to demonstrate, establish, operate and maintain the Global Positioning System (GPS), the Instrument Landing System (ILS), the Loran-C Navigation System, the Very High Frequency Omni-Range Navigation System (VOR) and the Microwave Landing System (MLS) with emphasis on spectrum management criteria including but not limited to the effects on system performance of collocated subsystems; the effects of site terrain and obstructions; analytical, modeling and measurement support of radio-frequency interference predictions and other spectrum management issues and technical support of the spectrum allocation and management programs of the International Telecommunication Union (ITU). The purpose of this synopsis is to determine if there are any responsible sources other than the incumbent, Ohio University, capable of supplying these services in a like manner. Interested and Qualified concerns are invited to submit a Statement of Capability to the Contracting Officer. All sources shall have demonstrable, direct, and recent experience and capabilities in the following areas: A.Global Positioning System. This shall include detailed knowledge of constellation availability, proposed techniques such as Special Category I, Wide Area Augmented System (SCAT-I, WAAS) for implementing differential GPS, calculation of power spectral densities for any digital or analog modulation method proposed for the differential datalink, and the interference potential of the differential datalink and L-Band sources for all categories of GPS operation from enroute to Category IIIb precision approach/landing. B.Instrument Landing System. This shall include modeling of type B2 (brute force/desensitization), type A2 (adjacent channel) and type B1 (intermodulation) interference to the ILS localizer from the FM Broadcast Band (88-108 Mhz). C.Loran-C Navigation System. This shall include it's use as a supplemental NAS element serving enroute, terminal and approach phases of flight, with emphasis on system performance assurance, optimization and integrity. D.VOR. This shall include modeling of type B2 (brute force/desensitization), type A2 (adjacent channel) and type B1 (intermodulation) interference to the VOR from the FM Broadcast Band (88-108 MHz). E. Loran-C Navigation System. Includes use as a supplemental NAS element serving enroute, terminal and approach phases of flight, with emphasis on system performance assurance, optimization and integrity. F. Microwave Landing System. G.Air Traffic Control System operations and procedures. H.System engineering, specifically applied to navigation and landing systems. I.Landing systems siting and performance criteria and siting optimization methods. J.Software engineering. Including but not limited to modeling and simulation of ILS/VOR signal characteristics, GPS signal characteristics, MLS angle, data and precision distance-measuring (DME/P) functions, Loran-C signal characteristics, and interference protection criteria adopted or proposed for national or international use. K.Detailed current knowledge of the spectrum allocation and management programs of the International Telecommunications Union. L.Detailed current knowledge of the ongoing work programs of the ICAO All-Weather Operations Panel (AWOP) and Obstacle Clearance Panel (OCP). M.Facilities and equipment owned or fully provided by the contractor before the contract goes into force, to perform work as outlined in the scope of work above, including: i.Airport facilities equipped with operational ILS, VOR, and MLS subsystem test beds and capable of mounting experimental equipment for evaluation including portable VOR facilities for GPS-based Special Category I (SCAT-1) interference testing, and DGPS ground equipment. ii. Aircraft equipped with the full range of instruments capable of detailed evaluations of MLS,ILS, VOR, GPS, and Loran-C signals and online processing of flight data including the ability to conduct flight tests of code-phase and kinematic-plase differential GPS. iii.Ground test capabilities for MLS, ILS, VOR, and GPS signals. Interested offerors should identify their ability to respond to therequirement by specifically addressing each of the criteria set forth above. Responses containing only company brochures, catalogs or other type generic information will not be evaluated. For the above criteria, all experience indicated should include relevant experience over the last three years, including a description of the work performed; the contract number, the identification of the Government or commercial agency for which the work was performed (identify all efforts performed as a subcontractor); and the name, title, and telephone number of the Contracting Officer and the Contracting Officer's Technical Representative. The response addressing each of the above criteria should be limited to twenty (20) pages excluding attachments. Inquiries and responses received within thirty (30) days after the publication date of this notice will be considered. No solicitation is available. Unsolicited proposals are not desired and cannot be accepted. The FAA will not pay for any information received nor for any administrative cost incurred. Telephone inquiries will not be accepted. Telegraphic responses will not be accepted. A determination by the Government not to open the requirement to competition based upon response to this notice is solely within the discretion of the Government. Information received as a result of this Notice of Intent will be considered solely for the purpose of determining whether to conduct a competitive procurement. Respondents will not necessarily be notified of the results of the evaluation. Responses to this notice should be sent in triplicate to the Contracting Officer, Mr. Jim Ammons, Federal Aviation Administration, ASU-320, 800 Independence Avenue, S.W., Washington, D.C. 20591.(0083)
