Abstract:A segment of submunition's discrete trajectory can be acquired by the means of intersection photogrammetry. Depending on the trajectory segment data, the submunition's motion state near the ground can be calculated. The calculating process is composed of several parts, which include removing the effect of horizontal wind, finding the plumb plane which the trajectory is in, determining the initial value of every variable, calculating the optimum solutions by use of progressive approximation, and calculating the submunition's motion state. Every part of the process is discussed in detail in this paper, and the computer simulation result is given.
Keywords:intersection photogrammetry  least square method  cargo projectile
