E-MAIL: Micheli Hull, mhull@mail.arc.nasa.gov. In order that potential sources may offer comments on the Satellite Communication System, a Request for Information (RFI) will be published on the Internet approximately August 11, 1997. Description of procurement: Information is requested on available satellite based communication systems and services to provide real-time, over-the-horizon data communications from small, pilotless aircraft to remote ground stations. The required aircraft-to-ground downlink data rate is 9.6 kbps minimum to 56 kbps and a control uplink of at least 250 bps. The airborne avionics and antenna system needs to be small enough to fit in small remotely piloted aircraft (RPA). This dictates a weight of less than 20 kg and minimal volume. The flight environment requires operaition from +50 degrees celsius to -60 degrees celsius, and sea level to 25 km altitude. Global area coverage is desired including the higher latitude and polar regions as possible. The system shall include ground terminal facilities for data and command input/output. The Satcom System will be used by the Environmental Research Aircraft and Sensor Technology (ERAST) Program which is a NASA-industry alliance for promoting the development of RPA's as high altitude and long duration science instrument platforms. Qualified parties should submit company profile and qualifications to identified point of contact no later than 5:00 p.m. on September 12, 1997. Responses may be submitted by mail, electronic transmission or by facsimile transmission. Any information marked as proprietary will be evaluated an protected, however, non-proprietary data is preferred.
