             abstract = "Actual, important problems of space dynamics are related to the 
                         protection of the Earth and its close space environment. This 
                         includes the study of disposal strategies for artificial 
                         satellites, the real-time propagation of space catalogues of 
                         thousands of objects, the fast prediction of orbit evolution of 
                         fragmentation models, among others. Accurate predictions of orbit 
                         dynamics require the integration of complete force models, 
                         including both gravitational and non-gravitational effects. The 
                         most accurate integration is expected from numerical methods. 
                         However, in many cases, it is important to have available tools 
                         for the instant propagation of the orbit evolution, as opposite to 
                         precise ephemerides computation. These tools can be implemented 
                         with the help of modern perturbation methods, which, in addition 
                         to the mean element propagation, allow for the recovery of 
                         short-period effects to provide osculating elements.",
