  7. Abstract:
  8. Nowadays there are various means in the field of orbital mechanics used in different levels and their accuracy depends on the theory and complexity of the governing equations used in their development. Most of them just simulate the motion of an orbiting satellite while there exist some commercial products able to provide the user with the orbital performance specifications and almost none of them have a module to design an orbit, based on a required performance such as specific coverage / ground track, shadow/light duration, etc .... Although satisfying performance requirements and a set of orbital elements simultaneously only seems to be possible for some particular orbits, there is an ever growing demand and a scientific shortage in this field, therefore the goal of this project is to study feasibility and generating the orbital elements based on performance characteristics of a specific mission. Since any novice user can have a set of anomalous input data, the design environment must be intelligent enough to inform the user at the very first steps. In addition 'since most of the equations in this area are nonlinear, constrained and even discontinuous classic and modern optimization methods are employed
