CASE STUDY

The centerpiece of the US Navy’s airborne Anti-Submarine Warfare (ASW) mis-sion is the Raytheon AN/AQS-22 Airborne Low Frequency Sonar (ALFS). The AN/AQS-22 is the only deployed “dipping active sonar” with multi-frequency opera-tional capabilities that adapts to varying environmental conditions and identifies threats sooner over a large area.

• Prior to the 1970s: Most submarines were noisy enough that a Passive Sonarcould detect them. The sonar would listen for submarine activities for detection.

• Post 1970s: With the emergence of nuclear submarines and noise dampingefforts, Active Sonar became necessary. The sonar sent out pings and listened forthe echo of the submarine for detection.

One of the most critical systems within the AN/AQS-22 is a high power digital signal processing Single Board Computer (SBC) and its Data Link that transmits tactical information back to the sonar operator. The AN/AQS-22 is integrated with the US Navy’s MH-60R Multi-Mission Helicopter, the MK 54 Lightweight Torpedo, and other battlegroup assets providing the US Navy with full detect and engage ASW capability.

CURRENT APPLICATION

The AN/AQS-22 was first deployed in 2002. The US Navy recognized that it was time for a “face-lift” to take advantage of the advancements made in the last decade in the areas of Electronic Warfare, Digital Signal Processing, and Data Link throughput. The AN/AQS-22 is composed of seven Weapon Replaceable Assemblies (WRA):

Acoustic Processor (proprietary US Navy furnished equipment) – Performs data processing of sonar return pulses and monitors maintenance data.

Sonar Transmitter/Receiver (ST/R) – Forms the sonar energy pulses and per-forms fault status monitoring.

Reeling Machine Interface Unit (RMIU) to MH-60R – Controls the AN/AQS-22 raise and lower functions.

Reeling Machine Control Unit (RMCU) to MH-60R – Is the reeling machine con-trol box with status display.

Reeling Machine (RM) to MH-60R – Raises and lowers AN/AQS-22 using hy-draulic power and provides electrical backup.

Reel & Cable (R&C) – 2,500ft coaxial cable typical

Transducer Assembly (TA) – Produces omni-directional pulses and deploys a receive array of 12 hydrophone stave arms.





TEVET SOLUTION

TEVET engaged directly with the engineering team at Naval Sea Systems Command (NAVSEA) and Raytheon IDS in San Diego to gain a full understanding of the application and the test challenges they were faced with. TEVET conducted a full gap analysis to gain further insight to what was required for today’s need and any future needs that might arise. Determining factors of the gap analysis for identifying the best COTS solution included: validating that Abaco’s XCR15 and PMC-0247RC met all the current required specifications, and that Abaco’s expertise in sonar applications made them uniquely qualified as an embedded solutions provider to meet NAVSEA’s future modernization efforts.

KEY DIFFERENTIATORS

• Abaco is a global leader in open architecture embedded solutions. Abacoenables customers to meet their interoperability objective for present require-ments, as well as future update requirements.

• SWaP/R – Abaco offers superior products for Size, Weight, and Power with 5levels of environmental Ruggedization.

• Cyber-security – Abaco builds cyber-security into every product to meet thestrictest military requirements.

• C4ISR – The foundation of every Abaco product is Command, Control, Com-munications, Computers, Intelligence, Surveillance, and Reconnaissance.

Raytheon has partnered with several sub-contractors to deliver and maintain this mission critical program, including Abaco Systems (formerly GE-Intelligent Platforms).

The US Navy placed a Total Small Business Set-Aside Solicitation on FedBizOpps for a quantity of 22 Abaco Systems XCR15 cPCI SBCs (Level 3) and a quantity of 22 PMC-0247RC Solid State Disk Drives (Level 3) to address their need to update their AN/AQS-22 system; as well as meet the DoD’s SDVOSB & HUBZone Small Business goals.

Broadens performance for both legacy and present

The XCR15 6U CompactPCI rugged Single Board Computer (SBC) utilizes the highly integrated 3rd Generation Intel Core i7 processor platform to help new programs achieve the optimum combination of throughput and cost for their application while minimizing the long term cost of ownership for customers by providing a straightforward, cost-effective upgrade path.

Building the XCR15 around Intel’s 3rd Generation Core i7 processor allows Abaco to offer integrated graphics and memory controller plus dual and quad-core processing all in one device. In addition to up to 20% (compute) and 30% (3D graphics) performance improvement over the previous processor generation, the third generation technology also brings Advanced Vector Extensions (AVX)



signal processing, intelligent performance on-demand with Intel Turbo Boost technology, PCIe Gen 3 (8 GT/sec) and USB 3.0 (10x the Bandwidth of 2.0) data transfer capability, and Hyper-Threading technology.

Ruggedization

The XCR15 is designed to meet the requirements of a wide range of applications from industrial through to fully rugged defense and aerospace programs. It offers extended temperature capability and a range of air and conduction-cooled build levels.

A Rich Software Choice

The XCR15 includes comprehensive Deployed Test Software (BIT and BCS) plus operating system support for Windows 7, Open Linux, Wind River Linux, and VxWorks.

ORDERING SELECTIONS



Abaco Systems was among the very first companies to bring to market commercial off-the-shelf (COTS) products that were rugged by design – as opposed to commercial products that were ruggedized as an afterthought.

Abaco’s five ruggedization levels offer increasing levels of environmental durability, enabling operational goals to be met at the lowest possible cost. Each ruggedization level has been carefully tailored to provide optimal trade-off between cost, performance, and reliability.
