R -- MATHEMATICAL AND GEODETIC TECHNICAL SUPPORT SOL RFO4-00025 DUE 042800 POC Richard M. Swanson, Contracting Officer, Phone (661) 258-7473, Fax (661) 258-2904, Email Richard.Swanson@mail.dfrc.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=24#RFO4-0002 5. E-MAIL: Richard M. Swanson, Richard.Swanson@mail.dfrc.nasa.gov. NASA/DFRC plans to issue a Request for Offer (RFO) for expert scientific, mathematical, geodetic and technical support to the Western Aeronautical Test Range (WATR) of the Dryden Flight Research Center (DFRC). Work will include highly specialized geodetic calcualtions related to space positioning, on-board guidance, trajectory predictions, etc., and other specialized support essential for the calibration of mission-critical tracking systems. The contractor will be required to provide technical documentation of mathematical algorithms, software and hardware systems, and procedures related to the acquisition and use of ground or on-board derived position and guidance data. Software support will include development of new or improved programs, subroutines, and software modules and furnishing analytical programs to test the accuracy and suitability of operational support hardware and software. The anticipated period of performance of this contract is Oct. 1, 2000 thru Sept. 30, 2001, with 4 one-year pricedoptions thru Sept. 30, 2005. NASA/DFRC intends to purchase these services from GMD Systems, Inc. of Lancaster, CA 93584. The statutory authority for this action is 10 U.S.C. 2304(c)(1)-Only One Responsible Source. GMD Systems currently supplies numerous company-owned mathematical algorithms used for reduction of mission data and, in support of the X-33 program, a large number of GMD Systems routines have been used throughout the planning, implementation, testing, and data reduction phases of the program. Only GMD Systems maintains up-to-date survey coordinates for all pedestals, calibration targets, runway end-points, and calibration targets at both Edwards and Dugway, as well as addition runway coordinates for Malmstrom AFB. Many of these points were installed under the supervision of GMD Systems or by GMD Systems. Additionally, GMD Systems wrote the simulation program that is currently used to evaluate radar tracking performance and coverage during any user-specified trajectory and maintains a company-owned radar data system that has been used for the development of new hard-ware and software needed to support many new projects (such as Pegasus) and for the analysis and correction of problems encountered on the real-time systems. No other contractor is familiar with the work that has been performed in support of the NASA Extended Range or possesses the same level of knowledge and expertise. A notice of this procurement will be publicized on the NASA procurement WEB site and in the Commerce Business Daily. The Government does not intend to acquire a commercial item or service using FAR Part 12. See Note 26. Also, see Note 22. An Ombudsman has been appointed. See Internet Note "B". All qualified responsible sources may submit an offer which shall be considered by the agency.
