Logos Technologies' Serenity hostile fire detection system has passed a test.

Serenity had previously been mounted on aerostats, but Logos tested a new version mounted on a tower, according to a company news release.

Serenity, which weighs less than 80 pounds, uses flash and sound sensors to detect the location of hostile fire.

"In mounting the system on a lower altitude mast, we needed to compensate for differences in range, and we've succeeded in doing that," said Frank Plew, Serenity project manager.

"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," Logos said.
