Lockheed Martin has selected Interstate Electronics to supply the anti-spoofing GPS navigation system for the Wind Corrected Munitions Dispenser (WCMD), a tail kit that convertsCBU-87/89/97 cluster munitions into all-weather, precision-guided weapons.
The TruTrak selected availability anti-spoofing module (SAASM) GPS receiver provides a secure, tamper-resistant means of decoding the US Department of Defense's GPS precise positioning signal, and is expected to enhance the fuzing process during the deployment of munitions dispensers. Interstate says it will help correct launch transients, ballistic errors and winds aloft.
Interstate is also developing and testing GPS anti-jam antennas and processors for potential use on protecting future weapon systems under a three-year Office of Naval Research contract. It will focus on development of several antenna arrays based on its STAP (scalable multi-element space-time adaptive processing) technology.
