Applied Physical Sciences and the Navmar Applied Sciences propose to adapt existing vector sensor and sonobuoy technology within their respective areas of expertise to develop a preliminary design for a passive deep water directional sonobuoy. The Phase I Base is centered on tasks pertaining to vector sensor design with emphasis on achieving the stringent noise floor criteria in an A-Size sonobuoy ...

Communication from ocean-surface sonobuoys to airborne platforms is critical to Anti-Submarine Warfare (ASW) operations. Existing Radio-Frequency (RF) solutions encounter several challenges which Free-Space Optical (FSO) systems solve. FSO systems for sonobuoy applications have unique challenges that proper system design can overcome. Verdant Networks is proposing an asymmetric system design that ...

Agiltron Inc. proposes to develop a compact, sensitive, and selective tunable diode laser absorption spectroscopy (TDLAS) based multi-gas sensor for OBOGS breathing oxygen monitoring. In the proposed research, novel laser diodes that output wavelength tunable from 2000 nm to 3500 nm will be used to dramatically increase the number of gases that can be detected and improve the sensitivity achievabl ...

Intuitive mission display visualization and planning capabilities are needed to enhance operator situation awareness when supervising teams of unmanned vehicles. To address this need, we will design and demonstrate Advanced Mission Display and Planning Tools (AMPT) to reduce the workload of re-planning and re-tasking teams of heterogeneous vehicles. These decision-support interfaces will use simpl ...

Future operations will increasingly utilize unmanned vehicles (UxVs) to accomplish complex missions. UxV"s have the potential to dramatically improve real-time situation awareness and increase mission success. Current advancements in performance and capabilities of UxVs and automated mission planning systems are enabling a shift from direct teleoperation towards supervisory roles. With this shift, ...

Retractable mooring fixtures are a critical component on the flight deck of a DDG51 class Navy ship. The chocks and bitts must be recessed below the deck level for helicopter operations, while reliably and easily deployed for mooring situations. The current mooring fixtures do not stand up to the highly corrosive environment of the flight deck and the lack of maintenance reduces the reliability of ...

The primary objective of the proposed research is to develop, and to demonstrate the feasibility of a mathematically rigorous approach for modeling and evaluating human supervisory control of multiple unmanned and/or autonomous vehicles. This high-level objective is decomposed into three inter-related goals: (1) the development of a mathematical model of human supervisory control, for individual o ...

One of the main obstacles to the useful exploitation of dimensionality reduction, both linear and nonlinear, is the lack of effective synthesis methods to generate examples in the original exploitation space, as opposed to the low dimensional parameter space. The ability to interactively navigate in the appropriate relevant low dimensional representation, and simultaneously observe the related"ori ...

Applied Physical Sciences (APS) has developed a plan to improve the design and development of submarine towed array vector sensors that employ single crystal accelerometers so that they meet Navy specifications, but do so at significantly lower cost relative to earlier variants. Tasks in the Phase I study include developing a comprehensive cost-model which will ascertain the feasibility of various ...

Arrays of vector velocity sensors have exhibited major system improvements over traditional omnidirectional hydrophones in undersea acoustic sensing. Compact accelerometers made from relaxor piezoelectric crystals are the key element which allow for the improved functionality of the vector velocity sensor arrays. These relaxor piezoelectric crystals are extremely sensitive and compact; but manufac ...
