The Gun (Elevation) Stabilization Bump Course (GSBC) of the Aberdeen Proving Ground (APG) is a special road test track which is used for quality testing of the line-of-sight (LOS) stabilized devices which are mounted into military vehicles. There are optical devices, antennas and guns which are components of the fire control systems for example. The methodology for the quality testing of the LOS stabilized devices using the design of the GSBC is the basic standard for appropriate devices testing in all NATO countries. We present a simulation model of the vehicle passing the GSBC in our contribution. The Matlab model generates vibrations of suspended parts of the vehicle. These vibrations can be used as the inputs in simulators of the suspended parts movement or as the input in simulation models of the servos of the LOS stabilized devices. The spectral parameters of these vibrations are estimated, too. We present simulations of the motor power component which is required for keeping quality of LOS stabilization process.
