A system and methods of an active protection system (or 'APS') for a platform. The APS has a threat cueing sensor provided at a first position on the platform where the threat cueing sensor detects a threat launched from a threat guidance system at a distance away from the platform. The APS also has a logic system operably connected to the threat cueing sensor where the logic system is adapted to determine an estimated location of the threat guidance system via a distance away from the platform. The APS also has a laser source operably connected to the logic system where the laser source emits a countermeasure beam directed at the estimated location of the threat guidance system to deter the threat away from the platform.

System and method for active protection system range estimation

A method for breaching a minefield comprising the step of deploying a shaped charge array from a vehicle to detonate the minefield.

Method for breaching a minefield

A method is provided for correcting errors in position derived from an inertial measurement unit (IMU), by performing a first zero velocity update at a time when the IMU is at rest, recording the time and position of the IMU at a subsequent start of a period of interest after the first zero velocity update, recording the time and position of the IMU at the end of the period of interest, performing a second zero velocity update at the end of the period of interest with the IMU at rest, and then recording a velocity indicated from the IMU, and deriving an accumulated error in position from the recorded data, by approximating errors in velocity by a function of time with a parameter determined from the recorded indicated velocity, and integrating the function over the period of interest to determine the accumulated error in position during the period of interest.
