Precision Lightweight GPS Receiver (“Plugger”)

This Precision Lightweight GPS Receiver (PLGR) was made by Rockwell Collins between 1993 and 2005. It is a handheld, five-channel, single-frequency GPS receiver designed to be used by the U.S. military to display position, velocity and time of day. It is generally referred to as a “plugger” or “handpack.” It has an antenna, keyboard, backlit display, receiver processor unit and memory battery. It operates off either a power battery or an external power source. Designed for use anywhere in the world, it is watertight and can be used with night-vision goggles. The unit is designed to be held in the left hand and operated with the left thumb. The jacks on the unit allow it to be installed in a fixed location as well as on moving vehicles. When operated in the ”time-only” mode it can calculate time to less than 100 nanoseconds. This instrument essentially replaced the PSN-8 Manpack GPS receiver that the U.S. military used in Desert Storm.
