Target Acquisition Designation Sight, Pilot Night Vision System (TADS/PNVS) is the combined sensor and targetting unit fitted to the AH-64 Apache helicopter. It comprises two independent systems, described below:
Target Acquisition Designation Sight (TADS)
TADS contains stabilised electro-optical sensors, a laser rangefinder and laser target designator. The TADS assembly can rotate +/- 120 degrees in azimuth, +30/-60 degrees in elevation and can move independently of the PNVS. The movements of TADS can be 'slaved' to the head movements of the helicopter crew to point where they are looking. This allows images from TADS to be projected onto the crew helmet mounted optical sights, overlaid upon their view of the cockpit and battlespace.
TADS contains a thermal imaging Infrared camera and daylight television camera. It also contains direct-view optics for use by the copilot/gunner (CPG).
Mounted above the TADS, the PNVS contains an Infrared camera slaved to the head movements of the pilot. PNVS can rotate +/- 90 degrees in azimuth and +20/-45 degrees in elevation. PNVS has a high rate of movement so as to accurately match the head movements of the pilot.
