Artillery GPS
The M1156 PGK GPS guidance
and navigation unit can be fitted
to 155mm artillery projectiles
with a deep fuze well to get
a step change in accuracy –
typically well under 30m.
It replaces conventional artillery
fuzes, requires no additional
modifications to the 155mm and
can have point-detonating and
proximity-fuzing options.
The US Army has demonstrated
the M1156 PGK in a number
of 155mm artillery projectiles,
including the M795A1, M549 and
the widely deployed M107. It has
also been successfully tested in
mortar bombs.SA Artillery
