A -- AUTONOMOUS STAR TRACKER FOR SOUNDING ROCKET FLIGHT SOL RFP5-14754/237 DUE 020395 POC Lorrie L. Eakin, Contract Specialist, (301) 286-4241 or Bradley J Poston, Contracting Officer, (301) 286-6843. THIS Is A REISSUANCE OF THE NOTICE PUBLISHED ON DECEMBER 12, 1995. THIS NOTICE Is TO INFORM CONTRACTORS THAT THE PROCUREMENT SOLICITATION TITLED ABOVE WILL NOW Be RELEASED ON OR ABOUT FEBRUARY 3, 1995, AND Is NOW BEING ISSUED ON A COMPETITIVE BASIS. NASA/GSFC intends to issue Request for Proposal (RFP)5-14754/237 on or about February 3, 1995 on a competitive basis to develop, test, and deliver one Autonomous Star Tracker (AST) that uses a Charged Coupled Device (CCD) for a detector and autonomously recognizes the inertial orientation of its boresight axis. The AST shall be delivered to Goddard Space Flight Center (GSFC) for integration into a sounding rocket as an experimental payload. The star tracker must be capable of surviving the sounding rocket flight environments and delivering the inertial attitude quaternion data to the rocket's telemetry system at a 5 Hz rate. The flight will attempt to prove that the unit can operate in the ''stars in, quaternion out'' mode. The star tracker must be capable of performing autonomous inertial attitude acquisition without a priori attitude knowledge within 5 seconds. NASA/GSFC anticipates awarding a firm fixed price contract, and delivery of the unit will be within 7 months of award followed by 3 months of launch support. Firms desiring consideration may request, in writing, a copy of the solicitation, within 15 days of the publication of this notice, to Ms. Lorrie L. Eakin, Contract Specialist, at Mail Code 287. All requests for this solicitation must identify the solicitation number (RFP5-14754/237) and the name, address, and phone number of the firm's point of contact. NASA shall consider all proposals submitted by responsible offerors. (0019)
