The mass center motion equations of a damp-increasing rangecorrection projectile were established by the concept of damp-increasing coefficients.

The rangecorrection efficiency can be enhanced obviously with strap-down SINS adopted, and the precision of the method for the quadratic model is higher than that for the linear model.
