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 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 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.
