A -- SUN SENSOR MINIATURIZATION DUE 090997 POC Otilia I. Rodriguez-Alvarez, Technical Officer, Phone 301-286-3194, Fax 301-286-1718, Email oir712@rs710.gsfc.nasa.gov WEB: Click here for the latest information about this notice, http://procurement.nasa.gov/EPS/GSFC/date.html#GCB712. E-MAIL: Otilia I. Rodriguez-Alvarez, oir712@rs710.gsfc.nasa.gov. NASA/GSFC is hereby soliciting information for potential sources for a sun sensor miniaturization study. The study is Phase I of possibly four phases to provide the spacecraft community with a sun sensor that utilizes new technologies to provide high pointing accuracy, large field of view and less power consumption in a greatly reduced mass and volume package. The scope of this study can be summarized as a cooperation with industry partners to develop new technologies to meet specified goals. Phase I is the release of the sun sensor miniaturization study to multiple vendors. Phase II occurs when GSFC receives the results of these studies, and identifies which technology approach provides the most feasible path to accomplishing the goals. The third and fourth phases are an industry partnering agreement between GSFC and a sun sensor vendor to share resources and capital to allow for the manufacturing of a sun sensor capable of meeting the Phase I performance goals and the product becoming available to industry. The specific goal of Phase I is to conduct a design study of a sun sensor capable of achieving the following performance parameters: Pointing Accuracy: 0.1 degrees or better (1 sigma); Field of View: 1 600; Spacecraft Spin Rate: 20 to 40 RPM; Power: 0.1 W or less; Mass: 0.225 kg or less. Areas of investigation should include, but not be limited to, optics, detector selection, circuit board technology, application specific integrated circuits (ASIC's), miniaturization, computing algorithms, and autonomous operation. The study should not only investigate current technologies, but should serve as a catalyst for examining new products and technologies currently underway as part of corporate internal research and development (IR&D), NASA SBIR's, and other technology related activities. No solicitation exists; therefore, do not request a copy of the solicitation. Interested vendors having the required specialized capabilities to meet the above requirement are invited to express their interest by submitting a brief capability statement with appropriate documentation, literature and brochures. All responses shall be submitted to identified point of contact no later than September 9, 1997. In responding reference the Sun Sensor Miniaturization Study. 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. Qualified respondents will be considered in any resultant solicitation for the requirement. 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.
