PERFORMANCE SPECIFICATION

NEXT GENERATION HANDHELD TARGETING SYSTEM (NGHTS)

1 Scope

This specification covers the Next Generation Handheld Targeting System (henceforth known as NGHTS) system as a foot-mobile replacement for the Portable Lightweight

Designator/Rangefinder (PLDR) & Thermal Laser Spot Imager (TLSI) suite of equipment.

1.1 System Description

The NGHTS is a handheld, lightweight, man portable device capable of performing rapid target acquisition, laser terminal guidance operations, and laser spot imaging. The principle functions of the NGHTS include: 1.) assisting the operator in determining the location of a target or other object of interest by measuring the distance, direction, and vertical angle from the operator to the object and 2.) allowing the operator to designate a target to enable the use of laser guided munitions. The NGHTS provides the Marine Air

Ground Task Force (MAGTF) with the capability to conduct Close Air Support (CAS) utilizing laser guided munitions. MAGTF Joint Terminal Attack Controllers (JTAC), Forward Air Controllers (FAC), Firepower Control Teams (FCT), Supporting Arms

Liaison Teams (SALT) of the Air Naval Gunfire Liaison Company (ANGLICO), and

Reconnaissance teams use the NGHTS to designate, mark, and handoff targets during amphibious and ground combat operations. Employment of the NGHTS reduces target location error and minimizes collateral damage especially while operating in an urban environment.
