- Description
- NASA/GSFC is hereby soliciting information about potential sources for Inertial Reference Units (IRUs) for the Solar Dynamics Observatory (SDO) Project of NASA/GSFC. SDO is the first mission under the Living with a Star (LWS) Program as part of the Sun Earth Connection (SEC). SDO will be made up of several instruments seeking to characterize the dynamic state of the Sun and enhance our understanding of the solar process and space weather. SDO is viewed as a follow on to the highly successful Solar and Heliospheric Observatory (SOHO) mission. SDO will be in a circular geosynchronous orbit of ~105 degrees longitude and with an inclination of 28.5 degrees. SDO will also have a mission life requirement of 5 years, with a goal of 10 years. SDO will be a three-axis stabilized satellite with spacecraft attitude knowledge requirements of < 10 arcsec and jitter requirement of less than 5 arcsec with a maximum expected rate range of approximately 2 deg/sec. The observatory will operate on 28 +/-7 V dc power. The SDO Project is interested in single fault tolerant, 3-axis inertial reference units and pertinent life test data. Requested information is as follows: MECHANICAL {Mass (kg), Size Envelope (cm), Vibration levels for qualification and acceptance (Grms), Description of mechanical interface/mounting (drawings requested)} ELECTRICAL {Description of electrical interface and voltage protection features, Description of power interface(s), Peak power consumption (W), Steady state power consumption (W), Input voltage range (+/-V), Inrush current (A)} THERMAL {(General interface, survival temperature range (deg C), Operational temperature range (deg C), Thermal dissipation (W) during steady state operation and any other significant mode.} PERFORMANCE: {Rate range(s) (deg/sec), measurement resolution for each range (deg/sec), Rate saturation output/output data outside the rate range (polarity signal or invalid data), scale factor, scale factor stability (PPM or %FS), scale factor linearity (PPM), scale factor asymmetry (PPM), bias (deg/sec), bias stability (deg/hr), bias temperature sensitivity (deg/sec/deg C), random drift (deg/sec), standard deviation of angle random walk (deg/hr^(1/2)), standard deviation of rate random walk (deg/hr^(3/2)), magnetic sensitivity} DATA {Type(s) of command and data interface available, Description of input commands and output telemetry (Command and Data Interface Control Document requested), Update rate of the IRU output (Hz), Type of rate output (Ex: whole angle, incremental angle, rate measurement)} RELIABILITY {EEE Parts classification (Class A/B), Mean Time Between Failure, State of component development. Component design lifetime (years), both in storage and on orbit. Number of hours of failure free operations both on orbit and during life test, Estimate of electromagnetic interference (EMI)} RADIATION {Total Dose at the part level (krad), Immunity, at the parts level, to single event effects (SEE) (MeV) and single event latchup (SEL) (MeV)} COST AND SCHEDULE {Typical cost and schedule for manufacturing, assembly, test and delivery}. Please note any operational difficulties and then mention subsequent design corrections. A list of heritage missions using the component is requested, with specific interest in previous uses at the geostationary/geosynchronous environment. If the currently available components differ from these heritage units, please briefly describe the design changes. No solicitation exists; therefore, do not request a copy of the solicitation. If a solicitation is released it will be synopsized in FedBizOpps and on the NASA Acquisition Internet Service. It is the potential offeror's responsibility to monitor these sites for the release of any solicitation or synopsis. Interested offerors/vendors having the required specialized capabilities to meet or exceed the above requirement should submit a capability statement of 15 pages or less indicating the ability to perform all aspects of the effort described herein. In addition, interested offerors/vendors may provide any relevant catalogs or other published product literature that may be generally available in hard copy form or on-line. There is no page limit for this information. Interested offerors with solutions that do not meet all specifications are encouraged to respond and note exceptions. This is especially true of existing designs where, if requirements are relieved, there are substantial savings. Responses must include the following: name and address of firm, size of business; average annual revenue for past 3 years and number of employees; ownership; whether they are large, small, small disadvantaged, 8(a), HUBZone, and/or woman-owned; number of years in business; affiliate information: parent company, joint venture partners, potential teaming partners, prime contractor (if potential sub) or subcontractors (If potential prime); list of customers covering the past five years (highlight relevant work performed, contract numbers, contract type, dollar value of each procurement, and point of contact - including address and phone number). If you respond via regular mail or facsimile, please provide an electronic copy in Microsoft Word format in addition to the printed version of your submission. Technical and procurement related questions should be directed as described below: Technical Questions: Andrew P. Maynard - Address: Mail Stop 596, NASA/GSFC, Greenbelt, Maryland 20771; Email andrew.p.maynard@nasa.gov Phone: (301) 286-4461; Facsimile: (301) 286-3823 Procurement Questions: Kathleen Tennant - Address: Mail Stop 464, NASA/GSFC, Greenbelt, Maryland 20771; E-Mail: Kathleen.M.Tennant@nasa.gov Phone: (301) 286-9378; Facsimile: (301) 286-1779 Please advise if the requirement is considered to be a commercial or commercial-type product. A commercial item is defined in Internet "Note A". [INTERNET ONLY (commercial product definition)]. If the requirement is considered to be a commercial-type product, please include information on customary practices regarding customizing, modifying, or tailoring of items to meet customer needs and associated costs. 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 the evaluation. Respondents deemed fully qualified will be considered in any resultant solicitation for the requirement. 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. Andrew Maynard at the address indicated above, no later than 10/10/2003. Please reference 03-GFH-SS-005 in any response.
