Feasibility Study Of Optimization Models For The MEXSAT System
Abstract
The Mexican Satellite (MEXSAT) system has a limited lifetime; therefore, it is crucial to evaluate and compare the performance of alternative techniques to achieve space communications, which could possibly improve the Mexican space communication capabilities. Furthermore, when compared to MEXSAT, the O3b constellation concept seemed to offer several benefits. The purpose of this thesis was to investigate the feasibility of acquiring satellite communications with more efficient performance for the Mexican Navy (SEMAR) as the main stakeholder, by adopting this O3b constellation concept. This research used STK software to develop, analyze, and compare different proposed satellite constellation models and their communication links with the current MEXSAT performance in order to evaluate the feasibility of getting a more capable and functional satellite constellation for Mexico. When modeling and comparing both communication capabilities, the research found antenna gain values were crucial to the efficiency of the links. Moreover, rain attenuation values were critical and significantly affected the performance of the modeled links at Medium Earth Orbit. Ultimately, our simulated results showed that the performance of the current MEXSAT system was superior to the modeled O3b constellations.
