Advanced Contact Management System is a new approach to generating the tactical picture directly from the raw acoustic data that is provided by the submarine sensors.
Submerged Acoustic Navigation System Beacon calculates a submerged vehicle’s position in real time over a large area using a single bottom mounted beacon emitting a synchronized coded ping.
Standardized Metrics Assessment of Readiness and Training is a performance assessment tool that provides real time and post event analysis capabilities. It assists with the critical question of “what happened” – the first step of any assessment. SMART does this by automatically recording data and events that yield insight into operator actions and system function.
In the world of passive sonar, actionable information is very limited. The only pieces of information available are the arrival angles and signal frequencies of acoustic energy from other underwater contacts.
With that information, commanding officers of billion-dollar naval assets infer vital actionable information.
But, how do they do that?
By directly processing the output of sonar sensors and unique feature extraction...
The ACMS produces the position and velocity information of sonar contacts... This is critical decision making information
With the information provided by ACMS, commanding officers can safely maneuver costly naval assets, precisely employ tactical weapons, and, most importantly, maintain our naval superiority.
SANS is an undersea acoustic positioning system consisting of a bottom mounted acoustic device (beacon/transponder) and an on-board tracking transceiver. SANS can simultaneously operate as an passive Self-Track (ST) positioning system resident on a submerged platform (submarine, unmanned undersea vehicle, remotely operated vehicle ….), as a Multi-Lateration (MT) positioning system resident on a third party platform (surface ship, aircraft, unmanned underwater vehicle and shore based range operations center) and as an acoustic telemetry system allowing digital communications between submerged and surface platforms. The self-track SANS estimates the x-y position of any passive (no range pinger) submerged platform while the multi-lateration SANS determines the x-y position of any underwater vehicle equipped with a ranging pinger.Play Video
The SANS Generation 4 Beacon is the fourth generation of the SANS Beacon designed and built by MIKEL. The SANS Beacon is an undersea, bottom-mounted acoustic device used by the SANS system to provide undersea ground truth to submerged vehicles. Beacon electronics consisting of a receiver/detector, transmitter/pinger and battery power supply is enclosed in a 17” glass sphere and protective hard-hat with acoustic transducer and acoustic release mounted on the hard-hat. The beacon is positively buoyant and is anchored to sea-bottom using commercial anchor. The beacon can be acoustically commanded to turn on, change ping rate, increase/decrease its source level or activate release for recovery. Once activated the beacon emits a periodic coded acoustic ranging signal used by SANS.
SANS was designed and developed as a passive acoustic positioning system used for precise navigation for any submerged vehicle. However, SANS technology can be used in many applications involving both Commercial and non-tactical and tactical Military operations. For example, SANS can be used as a precise navigation system for unmanned underwater vehicles UUVs and remotely operated vehicles (ROVs) performing various tasks such as harbor security, inspection of oil/gas platforms, environmental surveys, area search as well as tactical military operations including mine warfare, anti-submarine and anti-surface ship warfare, even STRIKE operations in GPS jammed or denied environments.
The U.S. Navy has heavily invested in the development and use of shore based and operational based simulators like Submarine Multi Mission Team Trainer (SMMTT) and On Board Team Trainer (OBTT). These simulators are essential to build and sustain the war fighting proficiency level of OODs and their supporting watch standers operating the tactical systems. The power of using simulators for training and ultimately operator and system performance evaluation is that “truth is known.” Including a performance measurement capability utilizing “truth” will enable the quantitative assessment of system performance as well as operator proficiency and forcewide war fighting readiness
SMART does this by automatically recording data and events that yield insight into operator actions and system function. Thus, compliance with procedures as well as assessment of system performance can be evaluated. While observation and feedback from experts on operator, team and system performance are frequently used methods for evaluation, feedback and improvement, these processes are more reliable and effective when executed with measured quantitative data assisted by the observed data. By making quantitative data available, evaluators and trainers are better able to assess performance, identify deficiencies and define remedial actions in the case of operator performance. Use of SMART allows for a standardized approach to operator, crew and system performance evaluation, both in the attack center trainers during training evolutions and shipboard during underway evolutions. Finally, integrating T-SMART into AN/BYG-1 in support of SWFTS will provide the automatic test tools so urgently needed for the test and evaluation of AN/BYG-1 systems under development.
T-SMART has been fully integrated as a module within AN/BYG-1 Tactical Control System (TCS) T-SMART functionality added to Multi-Purpose Interactive Trainer (MIT) Stand-Alone T-SMART delivered to SLC Norfolk and Groton
