Applied Technology Institute (ATICourses) offers a variety of courses on Acoustic, Noise & Sonar Engineering. The news below should be of interest to our readers.
COTS stands for commercial off-the-shelf stands for commercial items and available in the commercial marketplace that can be bought and used under government contract. Motivations for using COTS components include hopes for reduction of overall system-development and costs (as components can be bought or licensed instead of being developed from scratch) and reduced long-term maintenance costs.
Now COTS computer equipment for sonar signal processing designed by General Dynamics Corp. will be introduced to to US Navy submarines.
A $47 million dollars were granted to the company to deliver Multipurpose Processor (MPP) engineering services and Total Ship Monitoring Systems (TSMS) for Ohio-class missile submarines as well as on Los Angeles-, Seawolf-, and Virginia-class fast attack submarines. The goal of the Naval Sea Systems Command is to increase effectiveness of the following:
- towed array
- hull array
- sphere array
- sonar signal processing
The MPP is a multi-array interface receiver that provides signal conditioning for received array signals; data processing; digital formatting of data; beam formation; and signal processing for A-RCI display data.
The TSMS, meanwhile, monitors and localizes the submarine’s own noise sources including transients, so onboard sonar systems can compensate for it and improve its ability to detect and identify sound emissions from other submarines ad surface ships. The TSMS feeds its data to the MPP.
