The FireFly acoustic and electro-optical (EO) sensor can operate with Serenity Payload or be deployed as a stand-alone unit.
[1] The $45,000 cost of the FireFly sensor is small enough that systems are considered disposable if a failure occurs, yet its algorithms are capable of grouping threats into classifications of small arms fire, heavy machine gun, rockets artillery and mortar, geolocating the threat with a high degree of spatial accuracy.
[1] Reusing Existing Natural Energy, Wind & Solar system (RENEWS) was a microgrid solution providing alternative power sources to soldiers in combat.
RENEWS remedied this problem by producing self-sustaining solar and wind energy for combat technology.
