SONAR Systems & Sensors
Progeny Systems is a business area within General Dynamics Mission Systems that primarily supports submarine and surface fleet defense, security, and maintenance. Progeny Systems has been providing submarine SONAR capabilities for U.S. Navy submarines since 2002. Our systems consist of hardware, software, and technical advances to benefit warfighters underwater and on the surface, enabling mission-critical active and passive system capabilities including transmit capabilities, target and weapon tracking, underwater communication, and data collection.
Acoustic Intercept & Ranging (AI&R)
Acoustic Intercept & Ranging (AI&R) is an advanced real-time processing solution integrated into the SONAR systems of every U.S. Navy submarine in the fleet and is designed to autonomously detect underwater acoustic emissions. Acoustic data is collected from a multitude of hydrophones (sensors) mounted on or towed behind submarines or surface ships, and processed inboard using AI&R hardware and signal processing algorithms. Display-ready-data and alerts are then provided to SONAR operators for analysis and interpretation on workstations running the AI&R user interface.
Precision Acoustic Ranging System (PARS)
Precision Acoustic Ranging System (PARS) provides Virginia-class submarines with the ability to validate and calibrate SONAR arrays. The system can be deployed in any area at any time, eliminating the need for dedicated test facilities or an acoustic range. PARS consists of a submarine-launched Expendable Launch Vehicle (ELV) which generates acoustic emissions, and on-platform processing used to receive and analyze acoustic data. ELV output waveforms and hover depths are programmable, enabling PARS extensibility to many SONAR validation/verification applications.
Sonar Transit Group (TG)
Progeny Systems designs, develops, and delivers SONAR Transmit Group (TG) hardware for many U.S. Navy submarines. TG hardware consists of processing cabinets, analog power amplifiers, and SONAR interfaces needed by submarine platforms to enable acoustic transmit capabilities such as underwater communication, active sonar, ice draft detection, and depth sounding. Our design commonality approach reduces the Navy’s total ownership costs of transmit systems by allowing reuse of specialized components between several submarine platform types.
