B -- SATELLITE-BASED GLOBAL TELECOMMUNICATION INFORMATION DUE 032798 POC Clifford H. Arth, Technical Monitor, Phone (216) 433-3460, Fax (216) 433-6371, Email carth@lerc.nasa.gov WEB: Click here for the latest information about this notice, http://nais.nasa.gov/EPS/LeRC/date.html#3460. E-MAIL: Clifford H. Arth, carth@lerc.nasa.gov. NASA Lewis Research Center is hereby soliciting information from current and potential sources of satellite-based global telecommunication architectures or services that possibly could be used to satisfy portions of the data communications needs of NASA science and human exploration missions in earth orbit. A significant portion of NASA s space information network is characterized by major nodes such as; International Space Station, Space Shuttle, and Earth-orbiting spacecraft. This solicited information is needed to aid in planning for possible future NASA sponsored studies, technology development, and demonstrations that address NASA s potential use of and transition to commercial satellite communications systems for the NASA space information network. An important outcome is the identification of associated technical, legal, and regulatory issues. It is accepted by NASA that certain modifications/additions may be required to both NASA and commercial systems in order to enable such services. This possible future effort is likely to include feasibility and technical trades studies, financial business case analysis, and identification of any needed advanced technology developments. However, no solicitation for such future activities yet exists. For the current information request, qualified sources will have completed since 1992, studies or proposals involving any satellite-based global telecommunication systems for commercial or government sponsored initiatives. Respondents will have proposed or evaluated system level architectures for global communications applications and evaluated any necessary technology advances. Concepts are also invited that might lead to commercial service spin-offs from proposed approaches to satisfying NASA s space information network communications needs. Vendors having the capabilities necessary to meet or exceed the stated requirements are invited to submit appropriate documentation, presentation materials, study reports, literature and brochures. Any proprietary material must be marked as such so that confidentiality will be maintained. Any information on existing contractual vehicles with the U.S. Government that may be available for potential contractual arrangements should be also submitted. This synopsis is for information and planning purposes and is not to be construed as a commitment by the Government nor will the Government pay for information solicited. Respondents will not be notified of the results of NASA s evaluation of the materials submitted. Respondents deemed fully qualified may be contacted by NASA Lewis Research Center for further information or briefings, and will be considered in any resultant future solicitations on this topic. Firms responding should indicate whether they are a socially or economically disadvantaged business firm, an 8(a) firm, a small business, and/or woman-owned business. The Government reserves the right to consider a small business or 8(a) set-aside based on responses hereto. All responses shall be submitted to Mr. Clifford Arth, NASA Lewis Research Center, 21000 Brookpark Road, Mail Stop, Mail Stop 54-6, Cleveland OH 44135 no later than 30 days. In responding reference number 3460. (0058)
