A modification of the DS_{n}method is suggested to solve a transport equation numerically in a sphere geometry. Nonlinear correction is used to specify additional relationships/and quadratic formulae in terms of solution changes within a simple grid interval in a direction space. The modification proposed increases greatly the difference solution quality and removes a disadvatage of the DS_{n}method occurring when particle flows are transferred at great distances. The modification efficiency is confirmed by test calculations.
