Abstract:

A training apparatus, method and kit for remotely and substantially instantaneously evaluating the alignment, settings and levels of the aiming devices of a howitzer gun. The apparatus includes a video camera for manually removably attaching to the pantel and receiving the sight picture in the pantel or displaying a sight picture in a pantel eyepiece, a pantel deflection setting encoder for manually removably attaching to a pantel deflection setting device and encoding signals responsive to the pantel deflection setting, a pantel level encoder for manually removably attaching to the pantel and encoding signals responsive to the pantel level, a quadrant setting encoder for manually removably attaching to the quadrant setting device and encoding a signal responsive to the quadrant setting, a quadrant level encoder for manually removably attaching to the quadrant and encoding signals responsive to a quadrant level, and a data processing computer for receiving and analyzing the sight picture, or displaying or controlling a synthetic sight picture in a pantel eyepiece, for receiving the signals and for evaluation of the alignment, settings and levels.
