Firearm electronic system

An electronic firearm system for a man portable firearm comprising:

• a first inertial measurement unit/controller having at least three accelerometer assemblies with each accelerometer assembly having three orthogonal axes;
• a second inertial measurement unit/controller having at least three accelerometer assemblies with each accelerometer assembly having three orthogonal axes;
• wherein each of the at least three accelerometer assemblies in first inertial measurement unit/controllers are oriented to be coplanar with their orthogonal axes parallel to an x-axis, a y-axis and a z-axis and the at least three accelerometer assemblies in second inertial measurement unit/controllers are oriented to be coplanar with their orthogonal axes parallel to the x-axis, the y-axis and the z-axis;
• a control system programmed to use data from both the first and second inertial measurement unit/controllers to calculate the location and orientation of the man portable firearm with respect to a battlespace as well as calculating position and orientation with respect to a virtual coordinate system;
• an input/output module operatively connected to the first inertial measurement unit/controller and the second inertial measurement unit/controller, the input/output module including a global positioning system (GPS) receiver, a magnetometer and at least one transceiver for transmitting and receiving data;
• and
• a power source operatively connected to provide power to the input/output module, the first inertial measurement unit/controller and the second inertial measurement unit/controller.
