Systems has successfully fired 20
GPS-guided rounds as part of interim testing for the U.S. Army's
Precision Guidance Kit (PGK) Technical Development program. BAE
Systems' PGK team fired 20 155 mm projectiles equipped with its PGK
test modules at Yuma Proving Ground, Arizona.
The interim tests were the second series of successful gun-fired tests completed by BAE Systems on its PGK solution in less than two months. The testing included 20 rounds of various test configurations including fully autonomous GPS guided rounds. BAE Systems fired M549 Rocket Assisted Projectiles (RAP) to a range of about 20.5 kilometers. All test objectives were adhered with all rounds functioning properly. The GPS guided rounds demonstrated the ability to acquire GPS within the desired time and the ability to maneuver within the required 50-meter Circular Error Probable (CEP).
The Army will award a contract to the winner of the competitive shoot-off for development of PGK Increment 1, expected to be fielded in Fiscal Year 2009. The PGK Increment 1 requirement calls for a 155 mm PGK solution that can achieve an accuracy of less than 50 meters.
As mentioned in a 15APR2007 A-C-E post, the XM982 GPS-guided Excalibur round acheived CEP under 10m in recent tests.
A-C-E is primarily focused on the soldier and his tools, but it's also interested in anything which supports ground operations, including artillery.
