Coordinate transformation of warship pose and analysis of stabilization compensation

The general coordinate transformation method of warship pose nowadays was introduced,and the basis and drawback of these common methods were analyzed. According to the principle of compass,the pose of warship which was measured by compass is orderly in spite of the warship pose change is random. The coordinate transformation from geography coordinate(inertia coordinate)to deck coordinate of warship must be done conform to a order that is yaw—roll—pitch,however,order of coordinate transformation from deck coordinate to geography coordinate is pitch—roll—yaw. The equation of warship pose is deduced. It plays a solid theory foundation for the reality of warship stabilization platform and pose compensation. The conclusion can also be used in aviation,astronomy,control,and so on.
