Logos Technologies announced Thursday the tower-mounted version of its Serenity hostile fire detection system passed a live fire test last month in Arizona.

Serenity is designed to detect sources of enemy fire and is usually mounted on a high-flying tethered blimp, or aerostat, to provide city-size coverage the company said in a statement.

The latest modifications mean the system can now provide such coverage from towers.

Mounting the system on a lower-altitude mast required compensating for differences in range, taking Serenity one step closer to being put up on masts at U.S. bases and warzone installations, Logos said.

Fifteen such units have already been delivered to the U.S. Army, the company said.

Serenity combines two electro-optical pods with an acoustic sensor, developed by Hyperion Technology Group, to better react to incoming enemy fire and locate its point of origin.

The system, weighing less than 80 pounds and light enough to ride on drones, reduces the false alarms associated with other hostile fire detection systems, Logos said.

Serenity was developed in concert with the Army Research Laboratory.

Indra's InShield to protect Spanish A400M Atlas
Washington (UPI) Jun 16, 2016 - Indra's InShield has been selected to provide infrared countermeasure protection for Spain's A400M Atlas aircraft, the company announced Thursday.

The Indra system will protect the aircraft from surface-to-air missile attacks, the company said in a statement.

The Spanish Ministry of Defense contract for the characterization and verification of the first unit is worth about $4.4 million and will run until 2018.

System deployment is expected to begin in 2017 following testing and evaluation.

InShield, Indra's latest generation infrared countermeasure system, protects against attacks by MANPADS, relatively cheap and easily acquired by terrorist groups, that can be targeted when an aircraft is landing or taking off, the company said.

The system is activated when it receives a warning from the aircraft's missile detection array.

The countermeasure system then targets the head of the missile, where the guiding sensor is located.

A laser beam hits the missile's guidance system, confusing it and ultimately diverting the missile from its target, Indra said.

The system can divert multiple missiles simultaneously.
