Standardized Metrics Assesment 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.

Advanced Contact Management System

If SONAR were the eyes...

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?

Then ACMS is the glasses…

By directly processing the output of sonar sensors and unique feature extraction...

Submerged Acoustic Navigation System (SANS)

SANS Generation 3 Beacon

The SANS Generation 3 Beacon is the third 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 and battery power supply is enclosed in a 17” glass sphere and protective hard-hat with acoustic transducer and acoustic release mounted on 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/IMTS is a valuable tool to assess & validate performance while conducting Mine Countermeasure operations. The near real time debrief tool provides immediate in-situ feedback to allow my team to improve performance.” March 2014 USS Pasadena “SANS APB Demo”, Paul J paraphrased the SSN CO
We received feedback from a number of crew members, both low and high ranking. All of the PCO instructors, the COB, sonar senior chief, and a couple of the potential candidate officers all had very positive remarks. One of the high points of the system that they thought it was invaluable to be able to look at the image of a mine and determine why an HFA operator might have missed it (e. g., is the crew able to detect sphere shapes better than cylinders, is the mine buried, etc.). The Senior Chief said he would love to have it integrated into his system to train his crew. I’m really not exaggerating here, I got the impression that the crew was legitimately excited (one of the potential candidate officers gave me a fist bump). August 2015 USS Buffalo SANS support of SCC PCO OP, Joe B provided the following comments:

Tactical Standardized Metrics Assessment of Readiness and Training

Every problem...

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 Reporting System Image

Has a solution...

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.
