Firearm electronic system
Man portable weapons include integrated electronics that calculate orientation and movement in addition to providing that data to a user's heads-up displays (HUD) as well as to group and area networks. By passing data to a HUD, the user is able to see, virtually, the flight path, point of impact and other ballistic data as well as data representing the condition and performance of the weapon for any rounds fired. The HUD also displays the relative position of other members of the team, last known enemy area of operation and other useful parameters from the man portable weapons of the other team members through the network. The electronics may be integrated within the main components of any suitable man portable weapon in a non-intrusive way as to have no effect on the firing mechanism of the small arm when it is fully assembled.
1. 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
