Development of mission analysis toolkits

This thesis presents the development of a mission analysis toolkit for simulating controlled re-entry of spacecraft. The work was conducted during an internship at Deimos Space and aims to improve and expand an existing software solution. The developed tool, implemented in Python, provides a comprehensive framework for simulating sequences of perigee-lowering maneuvers and incorporates new functionalities, including orbit propagation and timeline generation. The software has been tested extensively to ensure accuracy and reliability. A key focus of the thesis is the computation of the ∆V needed and the optimization of maneuver strategies, adhering to ESA guidelines for controlled re-entry. The tool allows for detailed scenario analysis, addressing complex mission constraints, such as casualty risk mitigation and precise landing area targeting. In addition to serving as a report on the work performed, this thesis also acts as a user manual, offering comprehensive guidelines for the proper use of the developed software within Deimos Space. The developed toolkit remains available for future mission analyses at Deimos Space. By enhancing operational capabilities and improving the simulation of controlled re-entry scenarios, this thesis contributes to sustainable space operations and the reduction of space debris in low Earth orbit.
