The use of footscan balance test system of national high-level pistol, rifle shooters had a balance of stability tests, by analyzing the following major conclusions: First, all the athletes in men's pistol shooting athletes body posture and adjusting the balance of stability the capacity of the worst; the second, firing only state body sway eyes open area and before and after the shaking smaller decrease; and thirdly, the general balance of the stability of indicators (both before and after the body center of gravity, around shaking rate, trajectory length, shaking the area) can not accurately reflect the high level of shooting athletes balance the characteristics of stability, and derived indicators - per unit area of the track length (the total length of track and shaking the area ratio), both show the balance of stability, but also reflect the attitude adjustment ability, in the sway area certain circumstances, the greater its value, indicating that ability to regulate the more intense the frequency of shaking sooner, the better the stability of physical balance, in the actual shooting of firearms at the time of the impact of the smaller, can be used as shooting athletes evaluation and selection of indicators.

运用footscan balance测试系统对国家高水平手枪、步枪射击运动员进行了平衡稳定性的测试，通过分析得出以下主要结论：第一，所有射击运动员中男子手枪运动员身体姿态的平衡稳定性及调节能力最差；第二，射击训练只能使睁眼状态下身体晃动面积和前后晃动幅度减小；第三，一般平衡稳定性指标(身体重心前后、左右晃动幅度、轨迹长度、晃动面积)不能准确地反映高水平射击运动员平衡稳定性的特点，而派生指标——单位面积的轨迹长度(轨迹总长度与晃动面积的比值)，既显示平衡稳定性，又能体现姿态调节能力，在晃动面积一定的情况下，其值越大，表明调节能力越强，晃动的频率越快，身体平衡稳定性越好，在实射时对枪支的影响越小，可作为射击运动员的评价和选材指标。

On moving base, a new initial alignment algorithm for strapdown inertial navigation system is proposed. In the algorithm, two special inertial frames, the initial-time inertial frame (i0 frame) and the initial-time SINS body inertial frame (ib0 frame), are defined and are selected as calculation reference frames, then, the calculation of initial alignment direction cosine matrix is expanded into three parts:(1) the DCM between i0 frame and the navigation frame will be easily obtained via local geographical coordinates and initial alignment time;(2) attitude updating using gyro samples gets the DCM between SINS frame and ib0 frame;(3) by explaining SINS specific force equation in SINS body frame, the relation between velocity log, accelerometer measurement and gravity acceleration is established to achieve the constant DCM from ib0 frame to i0 frame.

在运载体运动情况下，提出了一种适用于捷联惯导系初始对准的新算法，该算法以惯性空间为参考基准，即建立了初始时刻惯性坐标系（i0系）和初始时刻捷联惯组惯性坐标系（ib0系）两个惯性坐标系，将初始对准姿态矩阵的实现分解为三部分：（1）通过地理位置和初始对准时间求解i0系至导航坐标系的变换矩阵；（2）使用姿态更新算法实时计算捷联惯组相对于ib0系的变换矩阵；（3）通过惯导比力方程变形，获得测速仪辅助测量、加速度计输出和重力加速度之间的关系，从中可以求解出从ib0系至i0系的常值变换矩阵。
