A portable, self-contained fire control system includes one or more of: 1) the means to provide geodetic positioning and navigational data for the host weapon platform in relation to established coordinate reference systems; 2) the means to digitally communicate with an off-platform command and control network; 3) the means to compute host platform ballistics data; 4) the means to indicate the current weapon orientation and additionally to indicate the horizontal and vertical weapon movements required to aim the weapon; 5) the means to inductively set fuzes for firing; 6) the means for digitally receiving and processing pre-computed mission data through to the fuze/projectile; 7) the means for locally computing mission data; and 8) the means for manually entering pre-computed data into the system.
