Target Coordinates. Reports the target's geographic location data (lat/long). The target coordinates are system
calculated using the aircraft's position and turret's orientation to determine location. Display units can be configured
by the operator. The location data and the accuracy of that measurement is determined by the current
measurement mode.
• In LOS mode – target coordinates are updated every 1 to 3 seconds – depending upon the target's
calculated slant range. LOS is the default measurement state.
• INS Alignment mode – Reports the current state of INS alignment checks. No target coordinates will be
reported. When aligned, the default LOS measurement state is initiated.

North Indicator

The North Indicator arrow is located in the top-left side of the display, and the arrow's point indicates the direction of
True North. Operators would use the arrow as a universal point-of-reference for describing ground movements
relative to an earth orientation rather than the aircraft's position. The arrow provides a witness marker on the video
so that the line-of-sight, of the captured video, can be later related to a cartographic map's orientation where the
page layout of north is always up. Display of this overlay element can be disabled.
