Abstract: A method is described of preventing weapon fire during operation of a self-contained gimbaled weapon system (GWS). The GWS has a sighting system, a weapon and a weapon cradle. The weapon cradle is elevated by an operator using a first elevation drive and moved in azimuth using an azimuth drive. In the method, the sighting system is moved using a second elevation drive and the azimuth drive to acquire a target based on signals received from a first operator interface and display unit located remotely from the GWS. The method further involves observing target information received from the first operator interface and display unit using a second observation unit having a display unit, and overriding operator control of the weapon based on the observation of the second observation unit to prevent firing of the weapon.
