A stable mount is secured firmly to the bed of a vehicle and is of sufficient height to reach an opening in the roof level. The stable mount has five primary parts made of a suitable material and constructed together with welds. The mount has sufficient rigidity such that the first resonant mode of vibration of the mount is greater than the post-actuation resonance of the mounted weapon so that optimal gun bolt actuation is realized and the jamming of rounds is prevented.

Disclosed herein are systems and methods of angular rate and position measurement that combine a small footprint with hardening and isolation technologies that allow it to function in acceleration, angular rate, noise and vibration environments that cause other gyroscopes to either fail or to produce erroneous outputs. An example embodiment contains a triad of accelerometers, a triad of gyroscopes, analog and digital ancillary electronics and a processor housed within a housing which is also filled with vibration reducing encapsulating compound. The disclosed systems and methods of angular rate and position measurement are capable of measuring and correcting internal errors and perturbations caused by the longitudinal and angular accelerations and temperature excursions of aerospace vehicles, isolating the gyroscope elements from the effects of acoustic noise and vibration, and accurately measuring the relatively small pitch and yaw oscillations of the vehicle in its flight path trajectory.

The fin lock system overcomes the major problems associated with the current deployment and locking mechanism by adding a center boss to the fin between the rear and front bosses and a sliding lock that engages between the housing and the center boss. The sliding lock, having a very low mass, engages with the center boss, and thus with the fin, very quickly and reliably when the fin reaches its fully deployed position, thereby arresting the motion of the fin and preventing it from rebounding. This, in turn, allows the aft-housing lug to lock the fin in its deployed position with one opening motion of the fin. The additional boss provides greater resistance to inertial and aerodynamic loads while the sliding lock completely eliminates both over-rotation of the fin and inconsistent engagement of the fin lock.
