A digital positioning system that interfaces with a portable weapon to automatically realign the weapon through and after a firing shock that saturates electronic components of the portable weapon. The digital positioning system includes a digital fire control device that receives target destination data. The digital fire control device transmits the target destination data to an automatic calibration and pointing device, which, in turn, generates a reference orientation from the target destination data. In response to the firing shock, the automatic calibration and pointing device acquires a current orientation of the portable weapon, independently of the saturated electronic components, and compares the current orientation to the stored reference orientation for causing a mechanical alignment and orientation mechanism to reposition the portable weapon.
