A -- REQUEST FOR INFORMATION ABOUT GPS PERFORMANCE-ENHANCEMENT AND ANTI-INTERFERENCE. POC Contract Specialist, Mr. John J. Berlin II, Code D211, (619)553-4501. The Navy is seeking solutions to upgrade GPS installations on its sea and air platforms to improve navigational capability and jamming resistance through use of available non-developmental-item (NDI) or near-NDI technologies in conjunction with advanced GPS receivers. In preparation, the Global Positioning System (GPS) Division of the SPAWAR Systems Center in San Diego (SSCSD) is compiling information about advanced RF component products and techniques that can improve position-velocity-time (PVT) accuracy and interference-rejection performance of operational GPS receivers. Gathered information will be used to provide the Navy a catalogue of available NDI or near-NDI components and systems through which the performance of current GPS installations can be improved. It is the desire of the Navy to consider new technology that offers improved capabilities with minimal impact to the integration of the GPS User Equipment within the host platform. Interest in an advantageous product will be followed by subsequent inquires to the contributor. Product information is desired for all components along signal path; such as, antennas, antenna electronics, amplifiers, connectors, and cables, which can improve satellite-signal-to-noise ratio at the GPS receiver. Information that concerns anti-jam technologies; such as, spatial filtering, digital-signal-processing techniques, noise excision filters, rapid acquisition technique, other noise/jammer-discrimination or PVT-improvement techniques, will also be welcomed. Technologies that are easily inserted in either the MAGR, MAGR 2000, EGI, GVRC or other Navy GPS equipment are of interest. Technologies that can improve antenna/antenna electronics performance with form, fit replacement of the current FRPA antenna, especially if they are of low radar cross section, or through the use of fiber optics are also of interest. In addition, information about technology that will allow multiple GPS receivers to operate from a single antenna with minimal signal-to-noise degradation is requested. The respondent should provide as a minimum the following information: (1) physical and functional description of the item being offered (size, weight, and external interfaces); (2) performance description and specifications of the item; (3) if possible state how the item can be integrated within existing or planned Navy systems and when it will be available; (4) if possible, include cost of item or technology now and anticipated in the future with further development; (5) if not yet NDI, provide the development status and anticipated schedule for completion. Even though this program aims toward Navy-specific installations, organizations that have contributed to similar solicitations by other DOD branches or Government agencies should respond here as well to assure exposure of their technology to the Navy. This announcement is a request for information and no contract will be awarded pursuant to this announcement. There is no bid package or solicitation document associated with this announcement. Therequested information is for planning purposes and does not constitute a commitment, implied or otherwise, that a procurement will be issued. However SPAWAR and the Navy will utilize the information for technical and acquisition planning. It is recognized that cost information which is provided by the contractor is a preliminary estimate for planning purposes; the contractor will not be bound to these estimates. Subsequent acquisitions may follow in the ways which best meet Navy needs. The government invites comments related to possible purchase or acquisition strategies. If there is a GSA or other contract vehicle already available for the technology being proposed, please include this information in the response. All data received in response to this RFI marked or designated as corporate or proprietary information will be fully protected from release outside the government. It is not the intent of SSC-SD to reimburse providers for the cost of submitting information in response to this RFI. Please direct any questions via e-mail to the POC, John J. Berlin II (jjberlin@spawar.navy.mil). To be beneficial, interested parties should submit any applicable information by November 24, 1998 via electronic transmission to the POC, or via two (2) complete sets of hard copy materials to the above address. In addition, parties who wish to do so may schedule a one-on-one information-gathering presentation for SPAWAR and SSCSD representatives, by contacting the POC. The overall presentation will not last longer than two hours. Such presentations, if scheduled, may take place at the San Diego, CA offices of SPAWAR and SSCSD during the months of December 1998 and January 1999 with exact timing and location to be mutually arranged. Parties are advised that SPAWAR and SSCSD are encouraging frank discussions and will ask clarifying questions but will not respond with comments or results of meetings. Parties will be expected to discuss their anticipated responses to specific considerations listed in this announcement. Posted 10/05/98 (W-SN258692). (0278)
