Training is Mission Critical

You need to understand how hard your soldiers are working, and when they’re training to their peak. You need the right tools to take your unit to the edge without going too far. Physiological Status Monitoring (PSM) is that tool.

Zephyr’s PSM Defense system gives you real-time visibility into the physical status of personnel operating in high stress and extreme environments. PSM measures vital signs in the context of posture and movement, and interprets the signals to help determine whether personnel are fatigued, dehydrated, injured or healthy.

PSM Defense is already operational for U.S. Special Forces, NASA, Navy SEAL units and first responders around the country.

PSM Defense has also been selected as the PSM system for the Land Warrior, Net Warrior and Department of Homeland Security PHASER programs. Zephyr PSM training systems are listed by the Inter Agency Board and hold a Motorola APCO Trunking Certificate of Validation.

All the data you need to for peak performance

With PSM Defense ECHO – conditioning, effort, stress and exertion can be quantified, recorded and analyzed. Measure when a solder thinks they’re giving their maximum effort – and use the physiological and mechanical output to close the gap.

With a built-in Live mode, squad leaders can view the intensity and load of each soldier at any point during training – giving you the cold hard data to see who’s maxing out, and who is hiding; who’s giving 110% and who isn’t; who’s able to push through the wall, and who has mental toughness.

And when concerns about health and injuries arise – you can rest assured you have the tools to know when it’s safe to push a soldier to their max zone – and when it’s time to back down.

Get the tools to get the results: increased conditioning and toughness.

PSM Defense ECHO Advantage

Knowing the real-time physical status of personnel in harsh, challenging environments can assist Commanders and Medics in Command & Control (C2), and Combat Casualty Care decisions that can affect the outcome of a mission. The PSM Defense system deploys over existing radio systems, thus increasing soldier effectiveness, while minimizing weight, hassle and the cost of deployment.

Streaming live data allows real-time insight into the potential of heat stress, fatigue and dehydration. The system allows the trainers to design drills and exercise regimes that will train each solder, and the unit as a whole, to their peaks, ensuring the highest level of performance.

PSM Defense ECHO generates customizable, detailed reports and analysis of individual and unit progress – including trend analysis of individuals over multiple sessions or sub sessions. Comparisons between individuals can be created quickly and easily allowing you to fine tune practice drills and exercise regimes to achieve individual and unit goals.

You no longer have to worry about guessing how your soldiers are performing. With Zephyr’s PSM Defense ECHO, you really can Measure Life…Anywhere!
