Abstract:
In this study, a model for the optimal routes for the recovery of space debris is expressed. The dynamic model using a binary system consisting of satellites and orbital debris containment space is extracted. Trastrhay available on satellite and aerodynamic drag on the system circuit changes the whole system and the entry of debris into the thick atmosphere began to burn.This circuit must be optimized. The thrusters are assumed as variable optimization problem. After simulation of optimization, it follows that by changing the initial value thrusters, Trastrhay the optimal cost function changes. Also, indicating the final height of system affects on parameters, thrusters and the cost function. And the additional indicating the final time fixed on the thrusters is ineffective, but on the cost function is very effective. One of the innovations of this project is using of the complkex and nonlinear dynamic model for the retrivial system and if companies apply this system to collect space debris, is a great development in this regard
