Lightweight Laser Designator Rangefinder (LLDR), AN/PED-1, 1A & 1B

Provide the dismounted Fire Support Teams, Combat Observation and Lasing Teams, and Scouts with a precision target location and laser designation system that allows them to call for fire using precision, near-precision and area munitions.

The Lightweight Laser Designator Rangefinder (LLDR) is a crew-served, Soldier-portable, long-range, modular target locator and laser designation system. The primary components are the Target Locator Module (TLM) and the Laser Designator Module (LDM). The AN/PED-1A (LLDR-2) reduced system weight by more than five pounds and reduced power consumption. The AN/PED-1B (LLDR 2H) improves target location performance.

The TLM incorporates a thermal imager, day camera, laser designator spot imaging, electronic display, eye-safe laser rangefinder, digital magnetic compass, Selective Availability/Anti-Spoofing Module Global Positioning System (SAASM GPS) and digital export capability. The original LLDR 1 (AN/PED-1) operates on one BA-5699 battery, but it can also use a Single Channel Ground and Airborne Radio System (SINCGARS) battery when laser designation is not required. A new compact laser designator is being fielded with the LLDR 2 (AN/PED-1A). It requires less power and operates on one common SINGARS battery (BA-5390 or BA-5590). To provide a precision targeting capability to the dismounted Soldier, PM SPTD developed the LLDR 2H (AN/PED-1B). It integrates a celestial navigation system with the digital magnetic compass in the TLM. The LLDR 2H provides highly accurate target coordinates to allow the Soldier to call for fire with precision GPS guided munitions. A Modification of in Service Equipment program will retrofit fielded LLDR 1 and 2 systems with the LLDR 2H precision targeting capability beginning in FY13.

The TLM operates as a stand-alone device or in conjunction with the LDM. At night and in obscured battlefield conditions, the operator can recognize vehicle-sized targets at more than three kilometers. During day operations, targets Soldiers can recognize targets at more than seven kilometers. The LDM emits coded laser pulses compatible with DoD and NATO laser-guided munitions. Soldiers can designate stationary targets at ranges greater than five kilometers.
