PLS or the Location Of Misses And Hits (LOMAH) uses an open acoustic sensor array to detect supersonic ammunition within millimetre accuracy. Used in conjunction with the Advanced Range Operating System (AROS), the marksman receives immediate feedback via the Intelligent Visual Display Unit (IVDU), or other graphic user interface device on their shooting performance and information on any sight corrections that may be necessary.

For sub sonic ammunition, a closed acoustic sensor array, radar or thermal PLS can be used. Should millimetre accuracy not be required, feedback to the firer can be achieved using electronic or vibration hit detection capabilities.

The savings to be achieved by using a PLS in terms of time, ammunition and training effectiveness is substantial. With over 50 years of experience in PLS technology, ATS is able to deliver the most accurate and versatile shot location capability in the world for small arms, tank or aircraft engagements.
