ERA provides the most advanced technology for today's air defense, security and military range operations.  

ERA's passive surveillance technology provides an unmatched ability to "see without being seen" and has a long heritage of innovation for leading defense and security forces around the world. Two of these important technologies are Passive Emitter Tracking (PET) and Passive Coherent Location (PCL).

ERA’s PET technology, Vera-NG by ERA, is a mature technology deployed in Asia, Europe and the USA, which tracks aircraft, vehicles, and other targets based on passive tracking of emissions, including jamming radar, transponders, DME, TACAN and other communication, navigation and surveillance systems.

One of the most promising technologies that could alter the field of air surveillance is the Passive Coherent Location (PCL) system.  For targets that do not emit signals, ERA’s PCL system tracks and classifies targets using reflections of existing third-party emitters such as FM radio. Since 2000, ERA has invested heavily in PCL technology and has participated in various demonstrations of the technology for NATO applications.

As the importance of air defense has increased for leading miltary forces, the importance of effective range management for training and combat missions has likewise received increased attention.  Era solutions provide accurate surveillance for challenging terrain and extreme climates. MSS by ERA provides mobile and fixed-range management solutions for the world's leading defense organizations.
