D -- PROCUREMENT OF TELECOMMUNICATIONS SERVICES POC GPS Glenn P. Stewart, Contracting Officer, 301-286-4345. The National Aeronautics and Space Administration (NASA) seeks sources or information for commerical telecommunications services equivalent to those currently provided by the 26m subnetwork of the NASA-ownded Deep Space Network. Upon successful procurement of these services, NASA intends to cease operations on the 26m subnet. NASA's target date to accomplish these tasks is 09/30/97, with some service overlap. Reimbursement for services is to be based upon fixed billing rates, which will include any amortized facilities construction costs. The 26m subnet currently provides S-band space to ground communications and tracking for earth orbiting spacecraft, including the Space Shuttle. In general, these spacecraft have not exceeding 2.3Mb/s. The 26m subnet is comprised of 3 antennas. They are located in Canberra, Australia; Goldstone, California; and Madrid, Spain. Each has an uplink power of 10kw and a G/T of approximately 39.4dB/K. Data is processed at either bit level or packet level. The 26m subnet services are operated and scheduled 24-hours per day. The proposed equivalent service are to be provided by three locations located approximately 120=B0 apart longitudinally and between 25=B0 and 35=B0 latitude, with a least on being north and another south. This service shall include delivery of data to the end user. Parties having the capability, either directly or with related commerical activities, to provide these services are invited to respond to this synopsis. They are requested to submit a statement describing their technical and operational approach and their prior experience with space-ground communications. Statements should include assumptions about use of existing Government-owned assets. Although detailed cost and schedule estimates are not required, statements shall include a discussion of proposed fee structure and contractual conditions and a discussion of how NASA's target date would be met. Statements shall not exceed 4 pages (excluding cover sheet). This synopsis is not a request for proposal and should not be interpreted as a commitment by the Government, however a formal RFP is contemplated is sufficient industry interest, capability, and commitment are demonstrated. NASA will consier all information provided by respondents with experience in providing space-ground telecommunications services and with the financial and programmatic resources in place to perform relevant tasks. Responses may be submitted by fax to (301)286-1724, by mail to the contracting officer listed above at mail Code 215, or via email to Glenn.Stewart@GSFC.NASA.GOV. Acknowledgement of receipt of information will not be made. Responses must be submitted within 10 days of the publication date of this synopsis. Questions concerning this synopsis should be addressed to the contracting officer listed above at (301)286-4345. Electronic versions of the documents will be provided on the World Wide Web at http://genesis.gsfc.nasa.gov/procure.htm, and by anonymous ftp to genesis.gsfc.nasa.gov/public/solicita. (0324)
