Air defense and passive surveillance are critical elements of today’s military and security operations. Stealth technology has necessitated a new breed of surveillance technologies. Due to its active design, traditional radar is vulnerable to airborne defense operations and anti-radar systems. Moreover, traditional radar is unable to detect all targets, proven by its inability to track stealth fighters.

ERA has created the ultimate, world-leading and advanced passive ESM tracker (PET), Vera. Vera-NG by ERA utilizes multilateration techniques to locate and track targets by triangulating on various electronic emissions in a broadband range, including emissions from transponders, radar, jammers and TACAN/DME interrogators. 

Due to its construction, Vera-NG by ERA is both mechanically and technically covert. The passive technology utilized by ERA allows for a virtually undetectable operation, as no signals are sent from the system. Additionally, it is designed to be completely unobtrusive, allowing for camouflage in any surface environment.
