During flight tests, March 2011, multiple real-time tracks generated by a wide-area persistent surveillance sensor (WAPSS) were autonomously cross-cued to a high-resolution narrow field-of-view (NFOV) interrogation sensor via an airborne network.
This system provides precise target location by incorporation of advanced Second Generation Forward Looking Infrared (Flir) [HTI Second Generation Flir -- WFOV: 8.0 x 4.5 degrees (16:9), NFOV: 2.6 x 1.5 degrees (16:9)], a global positioning interferometer, an eye-safe laser rangefinder [+/- 5 meters accuracy] and daylight TV sensor [WFOV: 6.0 x 4.5 degrees (4:3), NFOV: 2.0 x 1.5 degrees (4:3)].
