Precision Seekerless Guidance
PNAV

Lockheed Martin |
|
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.
