Corbitt, Contract Specialist, Phone (757)-864-2434, Fax (757) 864-9774, Email M.J.CORBITT@larc.nasa.gov WEB: Click here for the latest information about this notice, http://nais.nasa.gov/EPS/LaRC/date.html#1-084-DIH.1522. E-MAIL: Mary J. Corbitt, M.J.CORBITT@larc.nasa.gov. NASA/LaRC plans to issue a Request for Proposal (RFP) for a modification for a NASA-Owned Rockwell Collins Airborne Doppler Radar Receiver/Transmitter to Produce a Research Radar System Capable of Computer Controlled Waveform and Incident and Quadrature Data Recording. This action directly supports data collection from the Mobile Doppler Radar Facility and the NASA B-757 Flight Test facility with minimal effort. It will allow researchers to simulate various radar configurations and evaluate their effectiveness for specific phenomena on NASA developed algorithms. The NASA-owned Rockwell Collins weather radar system is comprised of several electronic boxes, an antenna pointing device, and a flat plate antenna. One of these electronic units, a receiver/transmitter, must be replaced with a unit capable of being programmed to simulate many different radar designs so that research can be conducted to verify optimal data extraction from both the electronic system design and the computational scheme. It is important that the equipment to be acquired be of flight qualified nature as it is expected to be experimentally operated from the NASA B-757 aircraft for research purposes. NASA/LaRC intends to purchase the items from Rockwell Collins Air Transport Systems, 400 Collins Road, N. E., Cedar Rapids, Iowa 52498-3161 under the authority of 10 U.S.C 2304 ( c )(1) Only One Responsible Source, and no other type of supplies or services will satisfy agency requirements. The Government does not intend to acquire a commercial item using FAR Part 12. See Note 26. See Note 22. An Ombudsman has been appointed. See Internet Note "B". Interested firms have 15 days from the publication of this synopsis to submit in writing to the identified point of contact, their qualifications/capabilities. Such qualifications/capabilities will be used solely for the purpose of determining whether or not to conduct this procurement on a competitive basis. Responses received after the 15 days or without the required information will be considered nonresponsive to the synopsis and will not be considered. A determination by the Government to not compete this proposed effort on a full and open competitive basis, based upon responses to this notice is solely within the discretion of the Government. Firm date for receipt of offers will be stated in the RFP. All qualified responsible sources may submit an offer which shall be considered by the agency.
