SIREN Passive Surveillance and Geolocation System (Model 570X)

The Model 570X SIREN is an extremely low size, weight and power system used for passive surveillance and precision geolocation of emitters — giving forward deployed forces a powerful advantage.

Using a non-obtrusive, active, time-based ranging technique, the SIREN system delivers precision geolocation capability in a form that weighs less than three pounds and uses less than 12 Watts of power. Intelligence gathering applications include network surveying, passive surveillance and emitter geolocation.

SIREN's small size and light weight make it ideal for a variety of ground-based, man-portable and airborne applications — especially tactical unmanned air- craft systems, where size and weight are critical factors.

SIREN can be paired with Raytheon's Model 650 ROGUE or Model 680 RAIDER wireless ground surveillance systems. In addition, industry standard interfaces for its power, command and control, GPS and antenna make it ready to use with other systems.
