ANAHEIM, CA – March 13, 2008 – L-3 Interstate Electronics Corporation (IEC), announced today that Alliant TechSystems, Inc. (ATK) has selected IEC’s TruTrak Evolution GPS receiver (TTE) as the key component of its guidance system for the U.S. Army’s Precision Guidance Kit (PGK) program.

The L-3’s TTE receiver is a gun-hardened, miniaturized GPS receiver designed for incorporation into the fuze well of munitions to provide positioning data for the guidance system. The PGK program allows the Army to outfit the existing inventory of High Explosive (HE) Rounds with a precision guidance capability providing a dramatic improvement in accuracy at a very low cost. The PGK design combines a proprietary aerodynamic steering technique with an extremely small system implementation allowing the guidance system to be incorporated into the space traditionally set aside for only the fuze subsystem.

“L-3’s TTE receiver will contribute significantly to the success of the Army’s Precision Guidance Kit program,” said Dave Wise, ATK Vice President and General Manager, Advanced Weapons. "We are pleased that it will cost-effectively enhance the performance of the system.”

“This is a major achievement for the PGK Integrated Product team,” notes Robert Huffman, president of IEC. “It validates the technical creativity and determination of the entire PGK industry team to provide a cost-effective, high performance solution.”

The selection was based on technical design and performance advantages of IEC’s TTE receiver coupled with the ability to meet the stringent cost targets set for the program. In order to maintain the demanding deployment schedule dictated by the program, IEC worked with ATK during the Technology Demonstration phase of the program to complete the final system design.

The ATK low-cost Precision Guidance Kit recently conducted a successful flight test at the Yuma Proving Grounds, Yuma, Arizona. The round maintained aerodynamic stability throughout its flight and successfully demonstrated an in-flight divert capability.  The requirements for Increment 1 are for the PGK to attain a Circular Error Probable of 50 meters or less.   The PGK program includes both an SDD development phase and three initial production runs totaling a minimum of 23,000 systems, with upwards of 45,000 units in this first increment.
