The paper considers the problem of a posteriori evaluation of maneuvers performed by active space objects. The numerical-analytic algorithms for evaluation of one-and two-pulse short-term maneuvers as well as one-pulse long-term maneuvers are suggested. Considerable attention is given to the speed and accuracy of the solution. The evaluation method for two-pulse maneuvers includes only one numerical cycle. This cycle iterates only the moment of the first-pulse; other parameters of maneuver are calculated analytically. Examples of calculations for maneuvering spacecraft in low-Earth orbit are included. The proposed method and traditional approaches to solving the problem of a posteriori evaluation of maneuvers are compared.
