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.

If this is the case, then it might be that the place where the program put the object is an area which is used by the program code itself, If this data is not really a drawable object but rather an executable code, the fact that it was put (because of the illegal coordinates) outside the region which belongs to data, and in a region which belongs to the program, might cause this code to be executed.

如果是这样的话，那么它可能是地方节目，把对象是一个地区，是由程序代码本身，如果这个数据是不是真正的可绘制对象，而是一个可执行代码的，但事实上，这是把以外的地区属于数据，并在一个地区，其中属于该计划，可能会导致这样的代码被执取消。
