3.2 PAYLOAD SENSORS

All sensors are mounted on the optical bench. The complete assembly is called the payload, which includes the
following sensors:
• EOW – Daylight Wide Angle
• EON – MX-Day/Night Spotter™
• IR – Infrared Thermal

EOW Sensor

The Electro Optical Wide (EOW) sensor is a daylight imaging camera that outputs color video. The sensor consists
of two parts:
• a 1-CCD camera body
• a continuous zoom lens

Operator Use
The lens's variable focal length provides the widest views for general observation and scene investigation.
Operators would utilize this sensor first to:
• orient turret steering
• examine a scene
• select a subject
For example, operators would use the EOW sensor to locate an area of interest within a scene and then center the
LOS reticle over a subject. They might zoom into the maximum capabilities of the EOW lens. For a more detailed
investigation, operators would switch to the higher magnification capabilities of the EON sensor to examine the
subject. If the subject moves out of the EON sensor's view, the operator would switch back to the EOW sensor to
re-acquire the subject.
Operating Temperature Limits
The EOW sensor is exposed to temperature fluctuations that occur inside the gimbal. The system monitors the
sensor's temperature and protects it from thermal extremes. The sensor will only be operational within the following
temperature control limits:
• For cold operation, the sensor will shutdown below -20°C and not restart until -10°C.
