Precision Seekerless Guidance – PNAV


A new seekerless precision strike weapon system developed by Lockheed Martin, could revolutionize next-generation strike weapons. This all-weather, precision standoff seekerless 1,000 lb weapon uses an inexpensive wing set to provide maneuvering G’s and energy to interdict evasive targets. Target cuing is received via datalink from other sensors, resulting in a near-zero navigation Circular Error Probability (CEP). The weapon uses low-cost, two-way data link to receive continuous corrections to the current GPS system, providing a direct hit without the use of an end-game seeker. The datalink provides weapon tracking and status. PNAV is expected to be a key ingredient in future Small Diameter Bomb (SDB) applications, as it enables reduction of CEP well below the 4meter requirement without a costly seeker.
