58 -- SATELLITE EARTH STATION & VSAT MAINTENANCE AND REPOINTING POC Vicki Holland, Contracting Officer, (303)236-5900 Concerns having the ability to furnish the services described herein are requested to give written notification (including the telephone number for a point of contact) to the procuring office above within forty five (45) calendar days from the date of this synopsis. The U.S. Geological Survey, Branch of Geological Hazards has a requirement for satellite Master Earth Station (MES) and very small aperture terminal (VSAT) maintenance and repointing services. The MES is located at the National Earthquake Information Center (NEIC) in Golden, CO. Approximately 80 VSATs are located through the CONUS region (approximately 60 of which are currently in service). The performance period for services will be December 15, 1995 through December 14, 1996. The repointing services will be required during June and/or July of 1996, coordinated with the end-of-life of the GE K2 satellite. Services required include: Remedial maintenance of the MES and VSAT equipment, including remote diagnosis of the MES, overnight exchange of failed MES modules, and timely exchange of failed VSAT equipment from a spares pool; emergency on-site MES repairs as needed and annual on-site preventative maintenance; repointing and peaking the MES antenna and up to 40 VSAT antennas as designated by the Government; and up to 100 EPROMS preset to the new outlink frequencies as need by the Government. The existing satellite system comprising the MES and VSATs was acquired from Scientific-Atlantic in 1990. Much of the system operating software is proprietary and much of the hardware, including the bust demodulators, outlink modulators, fail-over redundancy, and VSAT digital processing unit are proprietary to and are manufactured by Scientific-Atlanta. Offerors will be required to have an intimate knowledge of the satellite system from end-to-end, to have a spares inventory of critical MES components, to have VSAT spares pool and depot repair facilities, and to be able to produce Scientific-Atlanta model 4555 DPU compatible EPROMS. Based on information available at this time, and in accordance with 41 U.S.C. 253(c)(1), implemented by FAR 6.302-1, the Government consides the item specified as a sole source from Scientific-Atlanta, 420 N. Wickham Road, Medbourne, FL 32925, and proposes to negotiate a contract with that firm on that basis. However, should additional sources be identified, they will be considered. Firms who feel that they can furnish the required item or its functional equivalent (based upon the criteria specified herein) are invited to submit in writing an affirmative response to this announcement. An affirmative response would include literature, brochures and such other materials which correspond to the required items stated herein. This information will be evaluated and used to determine if competitive opportunities exist. Since no solicitation document exists, requests for such documents without accompanying information will be considered non-responsive to this request without further consideration. This notice may represent the Government's only official notice of this procurement. See Note 22. (0299)
