System passes detection tests at mast altitude ranges


FAIRFAX, Va. – June 15, 2016Logos Technologies announced today that a new, tower-mounted version of its Serenity hostile fire detection system has passed a live fire test this past May in Yuma, Arizona.

Designed to detect sources of enemy fire, Serenity is typically mounted on a high-flying tethered blimp, or aerostat, in order to provide city-sized coverage area. With the latest modifications, the system now provides coverage from towers.

“In mounting the system on a lower altitude mast, we needed to compensate for differences in range, and we’ve succeeded in doing that,” says Frank Plew, Serenity project manager at Logos Technologies.

The success of the May demonstration now means that Serenity is one step closer to being put up on masts at U.S. bases and installations in combat zones.

“We’ve already delivered a total of 15 Serenity units to the Army,” says Plew.

A dual-sensor system, Serenity combines two electro-optical (EO) pods with an acoustic sensor, developed by Hyperion Technology Group, to help friendly forces better react to incoming enemy fire by locating its point of origin.

Serenity’s optical sensor picks up the flash of enemy mortar or rocket fire and then calculates its point of origin and range from the sensor. The system’s acoustic sensor will then validate that enemy fire has indeed been detected by measuring the lag time between flash and bang.

Working together, these two Serenity sensors dramatically reduce the false alarms typically associated with other hostile fire detection systems.

“There are legacy hostile fire detection systems out there, and while they’ve proven the concept, Serenity reduces false positives and does a better job pinpointing sources of enemy fire,” Plew says.

Serenity weighs less than 80 pounds, light enough to go on unmanned aerial vehicles. It can transmit its fused optical/acoustic data to available full motion video cameras or wide-area motion imagery (WAMI) sensors.

Logos Technologies began working with the Army Research Laboratory (ARL) on Serenity in 2013, with the mast work starting in 2015.

Although the original concept was for Serenity to go on an aerostat with the Kestrel WAMI system, “Logos Technologies and ARL always envisioned it going on other platforms,” Plew states.
