99 -- REQUEST FOR INFORMATION FROM COMMERCIAL SOURCES FOR A CARIBBEAN (PRIMARY) GROUND STATION SOL RFI-96-GSN-001 DUE 070896. Contact Mr. Randy B. Ewing, Sr. Subcontracts Administrator, 410/516-7687; Ms. Susanna S. Ormond, Contract/Compliance Officer, 410/516-4378; Mr. Dennis McCarthy, Program Manager, 410/516-5545. Under NASA Prime Contract No. NAS5-32985, The Johns Hopkins University (JHU), Far Ultraviolet Spectroscopic Explorer (FUSE) program, is conducting a survey for a commercially available off-the-shelf (COTS) autonomous ground station to be installed in French Guiana. This will be the ``Caribbean'' (primary) ground station for all on-orbit FUSE operations. The FUSE Mission will be operated for three (3) years beginning in November 1998, using traditional pass (contact) operations methodologies. Although the Mission is normally implemented via pre-planned commands, the operations system shall also provide the capability for interactive, real time control of the spacecraft and instrument. Ground station to satellite contact coverage will be limited to an average total of 8 minutes of actual contact coverage time per satellite orbit. The autonomous ground station provides the satellite orbit. The autonomous ground station provides the interface to the on-orbit satellite, uplink command information prepared by the Satellite Control Center (SCC) at JHU, and receiving and forwarding to the SCC science and engineering telemetry. The Ground Station must be capable of transmitting data to and receiving data from the FUSE Satellite. The basis for the RF communication shall be the Cumulative Committee for Space Data Systems (CCSDS). The Ground Station will operate autonomously, receiving satellite and station commands from the SCC and passing satellite and station housekeeping telemetry back to the SCC. The Ground Station Concept, Ground Station Specifications, Ground Station Statement of Work, and other pertinent information, may be accessed on the Internet at http://fuse.pha.jhu.edu/fuse/rfi/rfi.html. Technical Information is requested on potential candidate systems/products to meet requirements outlined therein. Responses are requested by 08 July 1996. Commercial brochures and technical information may be submitted in hardcopy or via electronic media to: Mr. Randy B. Ewing, Johns Hopkins University, Department of Physics and Astronomy/144 Bloomberg Building, 3400 North Charles Street, Baltimore, Maryland 21218, (410) 516-7687 (rbewing@pha.jhu.edu). This synopsis is for planning purposes only and does not constitute a commitment on the part of The Johns Hopkins University to purchase the Caribbean Ground Station. (155)
