PNU & UPNU

The Position & Navigation Unit (PNU) and Universal Position & Navigation Unit (UPNU) utilize high-performance ring laser gyros to provide precision pointing and position location for sensors and weapons systems, and have been combat-proven on U.S. Army rocket and artillery systems.

The robust units feature GPS anti-jamming and spoofing capabilities, require no periodic calibration, and meet a range of military standards including MIL-STD-461E/464A, MIL-STD-810F, and MIL-STD-1275D.
