D -- JPL DATA REAL-TIME PROCESSING SYSTEM FOR SYNTHETIC APERTURE RADAR SOL 97/10 DUE 071497 POC William Rodriguez (818) 354-2830; FAX (818) 354-3494 E-MAIL: Data Real-Time Processing System, douglas.hughes@jpl.nasa.gov (Technical) and william.c.rodriguez@jpl.nasa.gov (Admin.). The Jet Propulsion Laboratory/California Institute of Technology (JPL/Caltech), operating under a prime contract with the National Aeronautics and Space Administration (NASA), is considering the integration of a Commercial Off-the-Shelf (COTS) automated system that ingests SAR satellite data telemetry and produces L0 products, all in real-time. Conceptually, the input would be raw signal data from a data switch and/or tape and the ouput would be L0 data to disk files. The purpose of this notice is to solicit information on the availability of such a system from private industry. JPL provides system design, development, procurement, and integration to the University of Alaska, Fairbanks (UAF) Alaska SAR Facility (ASF) through the Alaska SAR Facility Development (ASFD) Project. ASF's primary mission is to acquire, process, archive, and distribute satellite SAR data for the U.S. Government and research communities. ASF is housed within the Geophysical Institute at UAF and is primarily funded through NASA's Office of Mission to Planet Earth. The SAR satellites, currently serviced by ASF, are the European Remote Sensing Satellite-2 (ERS-2), Japanese Earth Resources Satellite-1 (JERS-1), and Canadian Space Agency RADARSAT. There are four initial requirements that ASFD will levy on any system that would be seriously considered: (1) The system shall be able to ingest ERS-2, JERS-1, and RADARSAT data from an ECL interface and store the data on disk in real-time; (2) the system shall be able to ingest raw signal data downlink at a sustained rate of the existing serviced satellites (now 105 Mbits/sec) plus margin for a base sustained rate of at least 150 Mbits;/sec; (3) the system shall detect and correct for reverse bit ordering the raw data signal, as in the case of a spacecraft recorder playback; and (4) the system shall create L0 product from the ingested raw signal data. Provide information on how your system would support the following five items: (1) The system shall be able to transform raw telemetry data into L0 files of configurable sizes; (2) the system shall be able to overlap raw telemetry data in the L0 files by a configurable percentage; (3) the system shall provide a redundant implementation that eliminates any single point of failure; (4) the system shall support Consultative Committee for Space Data Systems (CCSDS) packet telemetry and Reed-Solomon decoding/error correction; and (5) the system shall support data Quality, Quantity, and Continuity (QQC) metrics and reporting. Also provide, if possible: (1) Complete L0 product description; and (2) Complete operator interface description, including error and status messages. We invite comments on the requirements and information on applicable products. Please submit two (2) complete sets of any applicable information by July 14, 1997 to the JPL point of contact. Please direct any technical questions via E-Mail to douglas.hughes@jpl.nasa.gov and any administrative questions to william.c.rodriguez@jpl.nasa.gov. All data received in response to this Request for Information (RFI) will be treated as proprietary and will be used only by the ASFD Project for planning purposes. The data will not be delivered or presented outside of NASA. It is emphasized that the requested information is for preliminary planning purposes only and does not constitute a commitment, implied or otherwise, that JPL will solicit you for such a procurement in the future. Neither JPL nor the Government will be responsible for any costs incurred by you in furnishing this information. This is not a Request for Proposal (RFP). (0181)
