• Corrects vertical target location errors for GPS*-aided, INS**-guided munitions
  • Maintains small circular error probability (CEP) for long-range engagements when large vertical target location errors are present
  • Incorporates Mustang's Fuze Air-to-Surface Technology (FAST) precision proximity sensor


THE PROBLEM

GPS-aided, INS-guided rely on accurate geo-location targeting data to minimize weapon miss distance. Target location errors from a variety of sources will increase the weapon miss distance. Today, a near-vertical weapon impact angle is a method to reduce vertical location errors and their effects, but this method minimizes launch conditions.

THE SOLUTION

The FAST proximity sensor accurately estimates the altitudes of the weapon and its desired aimpoint using the sensor's ground profiling capability. Combining this information with the weapon's GPS and / or INS system virtually eliminates any altitude error and associated miss distance.

THE APPROACH

Mustang developed PSAG signal processing algorithms and a high-fidelity simulation, integrated FAST into a low-cost test airframe, conducted low-cost drop tests, and verified simulation performance predictions.

THE TECHNOLOGIES

Low-cost, high-performance radar; RF and digital electronics; real-time signal processing; advanced algorithms; guidance and control; efficient, low-cost drop tests.
