I spun up my inertial to a get ground speed indication to kind of give me a rough guess 我操纵惯性读数系统得到地速显示，多少估计出飞行速度。

By means of temporary stability of combining drift coefficient of angle sensor and through missile rotating two - position measurement , measuring rotating angle between the two positions by vertical sensitive axis x , and sensing the changes of ground velocity component between the two positions by horizontal sensitive axis and z , the position of the component is determined to realize the azimuth alignment before launch of tactical missile 角敏感元件漂移系数具有短期稳定性，通过转弹前后两位置对组合的测试，垂直敏感轴计测转弹过程中两位置之间的转角，两水平敏感轴敏感计测地速分量在前后两位置的变化，由此计算出部件当前所在方位，从而实现战术弹射前的方位对准。

3 . the project using ins / gps system data to estimate the angle of attack and sideslip is brought forward first . this project using the ins / gps system data , such as acceleration and velocity signal , and others signals of the aircraft , such as gyros and the mathematic models , to estimate virtual signal 首次采用ins gps系统数据来估计迎角和侧滑角传感器参数原理和方法，利用ins gps系统测量的地速和总加速度信号结合飞机其他传感器和数学模型估计得到了迎角和侧滑角传感器的虚拟信号，该种方法具有很好的实时性。
