A -- BROAD AGENCY ANNOUNCEMENT FOR FIBER OPTIC TOWED ARRAY (FOTA) HEADING SENSOR SOL N00024-00-R-6328 DUE 101800 POC 02632C, Ms. Cynthia Miller, 703-602-7707 Broad Agency Announcement for FIBER OPTIC TOWED ARRAY (FOTA) Heading Sensor: The Naval Sea Systems Command, Advanced Systems and Technology Office (ASTO), Arlington, VA is soliciting development of new and innovative designs and concepts for a passive fiber optic heading/roll sensor capability for fiber optic towed array applications which meets the following optical, performance, environmental, and mechanical goals. A fiber optic towed array (FOTA) heading sensor consists of a three-axis magnetic field sensor combined with a roll sensor such that an accurate heading may be computed regardless of the orientation of the device with respect to vertical. The FOTA heading sensor must operate without using electrical power at the sensor element. It must be capable of operation and optical interrogation over a fiber optic link up to 3 km in length. If magnetic biasing is employed to operate the sensor, any power or control signals must be supplied over the fiber optic link. Additionally, the sensor approachmust be capable of multiplexing; at most, two optical fibers (single mode preferred) may be used to interrogate a suite of up to 12 heading/roll sensors. Performance: Horizontal accuracy Hx and Hy +(50 gamma + 0.2%H) where H is the magnitude of the horizontal field Vertical accuracy Hz +2000 gamma Roll Normal operation throughout 360o Pitch Normal operation to +5o Heading resolution < 0.00549o Roll resolution < 1.40625o Repeatability +0.05o Note: Repeatability is the peak difference between any two consecutive sensor readings taken without changing the position of the sensor or the applied magnetic field. Computation time to make individual heading reading < 1.0 second Environmental: Operating pressure 1000 psi absolute Max survival pressure 2500 psia Operating temperature -2oC to +40oC Magnetic environment Earth's natural magnetic field Note: no accuracy requirements exist at temperatures above 30oC in combination with field ratios (the ratio of the magnitude of the vertical component of the earth's magnetic field to the magnitude of the horizontal component of the earth's magnetic field) > 6. Storage temperature -28oC to +65oC Operating medium ISOPAR L Mechanical: The FOTA heading sensor shall fit within a cylinder 0.625 inches in diameter and 5.1 inches long. All input/output optical fibers must exit from the forward end of the sensor. A strain relief 1.0 inches long is permitted on the input/output fibers. The sensor must survive a 3-foot drop to a hard surface when mounted in the next assembly consisting of a 16-rope assembly inside of a longitudinally reinforced polyurethane hose. ASTO intends to develop new FOTA heading sensor concepts and technology, to build and test a three-sensor prototype, to subsequently build and test a twelve-sensor advanced development model (ADM), and to collect performance data at sea. The scope of this broad agency announcement (BAA) includes relevant research, analysis, design, fabrication and testing of FOTA heading sensors. A two year phased effort is envisioned, with planned contract funding (if available) as follows: FY 2001 FOTA heading sensor design; critical component prototyping & testing; prototype sensor fabrication; prototype sensor performance & environmental testing $500K FY 2002 Prototype heading sensor/FOTA integration and lake test support; FOTA heading sensor ADM final electrical/mechanical design; ADM fabrication, integration & testing $500K This BAA will be open for 60 days from the date of the announcement. Proposals may be submitted at any time within that period. Early submission of proposals is desirable and encouraged.
