58 -- K-BAND PHASED ARRAY ANTENNA SOL 3-150042 DUE 061500 POC Michael J. Kinkelaar, Contract Specialist, Phone (216) 433-2736, Fax (216) 433-2480, Email Michael.J.Kinkelaar@grc.nasa.gov WEB: Click here for the latest information about this notice, http://nais.msfc.nasa.gov/cgi-bin/EPS/bizops.cgi?gr=D&pin=22#3-150042. E-MAIL: Michael J. Kinkelaar, Michael.J.Kinkelaar@grc.nasa.gov. NASA/GRC plans to issue a Request for Proposal (RFP) for the design and fabrication effort required to deliver (1) one 19 GHz, K-Band Phased Array Antenna system to NASA GRC. NASA/GRC intends to purchase the items from Raytheon Systems Company.Justification for Other Than Full and Open Competition with Raytheon Systems Company has been prepared using 10 U.S.C. 2304(c)(1), Federal Acquisition Regulation, (FAR), 6.302-1. "Only one responsible source and no other supplies or services will satisfy agency requirements". In 1997, NASA GRC entered into a Cooperative Agreement (NCC3-497) with Texas Instruments (now Raytheon Systems Company) to develop a high data rate, scanning, dual beam, phased array antenna system as part of the Direct Data Distribution (D3) experiment which is slated to fly as a Hitchhiker payload on a future flight mission. NASA GRC requirements dictate the need for an identical copy of the phased array for in house pre-flight testing, risk mitigation and performance evaluation. In house testing is required to characterize the phased array antenna system to assure its proper operation in space environment. Having only one contractor owned phased array antenna system would expose NASA GRC to unnecessary risks (test accidents, catastrophic failures etc.), all of which could produce costly delays to the flight experiment schedule. A backup array, owned by NASA GRC, would reduce these risks significantly. In addition, award to any other company other than Raytheon Systems Company would result in (a) Substantial duplication of cost to the Government that is not expected to be recovered through competition; or (b) Unacceptable delays in fulfilling the agency's requirements. The Government does not intend to acquire a commercial item using FAR Part 12.See Note 26. See Note 22. Interested organizations may submit their capabilities and qualifications to perform the effort in writing to the identified point of contact not later than 4:30 p.m. local time on June 15, 2000. Such capabilities/qualifications will be evaluated solely for the purpose of determining whether or not to conduct this procurement on a competitive basis. A determination by the Government not to compete this proposed effort on a full and open competition basis, based upon responses to this notice is solely within the discretion of the government. An Ombudsman has been appointed. See Internet Note "B". All qualified responsible sources may submit an offer which shall be considered by the agency.
