ATK [ATK] last week that with the Army it conducted a successful series of flight tests of its the company’s 155mm Howitzer Precision Guidance Kit (PGK) at Yuma Proving Ground, Ariz.
The successful tests are milestones in the rapid System Design and Development phase of the program, leading to a Critical Design Review (CDR) this summer, the company said.
PGK is a GPS guidance kit with fuzing functions for artillery projectiles. The kit allows the projectile to steer itself to a pre-programmed position, thus reducing ballistic dispersion of artillery projectiles.
The PGK has a GPS-hardened, fixed canard guidance and control package with gun-hardened electronics, a self-generated power supply and a minimum number of moving parts. It fits into the existing fuze well of existing 155mm high-explosive projectiles.
