1、速度坐标系。 原点O取在导弹的质心上；ox3轴与速度矢量v重合；oy3轴位于弹体纵向对称平面内与ox3轴垂直，向上为正；oz3轴垂直与x3oy3平面，其方向按右手定则确定。 2、弹体坐标系。 原点O取在导弹的质心上；ox1轴与弹体纵轴重合，指向头部为正；oy1轴在弹体纵向对称平面内，垂直与ox1轴，向上为正；oz1轴垂直与x1oy1平面，其方向按右手定则确定。 3、弹道坐标系。 原点O取在导弹的质心上；ox2轴与速度矢量v重合；oy2轴位于包含速度矢量v的铅锤平面内，且垂直于ox2轴，向上为正；oz2轴垂直与x2oy2平面，其方向按右手定则确定。 4、地面坐标系。 原点A取在导弹质心在地面上的投影点，Ax轴在水平面内，指向目标为正；Ay轴与地面垂直，向上为正；Az轴轴垂直与xAy平面，其方向按右手定则确定。 |

1.Velocity coordinate system Select the mass center of the missile as origin O; align ox3 axis with the velocity vector v; make oy3 axis perpendicular to ox3 in the longitudinal and symmetric plane and the positive direction be upward; make oz3 axis perpendicular to the x3oy3 plane and its direction determined by right-hand rule; 2. Missile coordinate system Select the mass center of the missile as origin O; align ox1 axis with the longitudinal axis of the missile and the positive direction be pointing to the head; make oy1 axis perpendicular to ox1 in the longitudinal and symmetric plane and the positive direction be upward; make oz1 axis perpendicular to the x1oy1 plane and its direction determined by right-hand rule; 3. Trajectory coordinate system Select the mass center of the missile as origin O; align ox2 axis with the velocity vector v; make oy2 axis perpendicular to ox2 in the plumb plane containing the velocity vector v; make oz2 axis perpendicular to the x2oy2 plane and its direction determined by right-hand rule; 4. Ground coordinate system Select the projection of mass center of the missile on the ground as origin O; make Ax axis in horizontal plane and be positive when pointing towards the target; make Ay axis perpendicular to the ground and be positive when pointing upwards; make Az axis perpendicular to the xAy plane and its direction determined by right-hand rule 供参考，希望有帮助 |
