When firing artillery, there is typically a maximum angle that the platform cannot exceed relative to the Earth plane. This is due to the large recoil forces involved and the risk of destabilizing the platform the weapon is mounted to. Mobile systems are particularly sensitive to this as the attitude of the platform relative to Earth is constantly changing. A simple solution is to add pitch and roll sensors directly to the platform. However, many mobile systems already have an assortment of sensors that can be used to calculate the platform attitude.This report provides a method to calculate the yaw, pitch, and roll attitude of the weapon platform relative to Earth as well as determine the maximum resulting platform cant and the heading of that cant relative to the platform. These calculations are performed using feedback from sensors providing yaw, pitch, and roll attitude of the gun relative to Earth and azimuth and elevation angles of the gun relative to the platform.
