CubeSat platforms can provide a cost-effective multiple-mission space system using state-of-the-art technology. This paper presents a new approach to CubeSat constellation design for multiple missions using a multi-objective genetic algorithm (MOGA). The CubeSat constellation system is proposed to perform multi-missions that should satisfy global Earth observation and regional disaster monitoring missions. A computational approach using a class of MOGA named non-dominated sorting genetic algorithm II is implemented to optimize the proposed system. Pareto optimal solutions are found that can minimize the number of satellites and the average revisit time (ART) for both regional and global coverage while maximizing the percentage coverage. As a result, the study validates the feasibility of implementing the CubeSat constellation design with an acceptable level of performance in terms of ART and percentage coverage. Moreover, the study demonstrates CubeSat\u2019s ability to perform a multi-missions.<\/jats:p>","DOI":"10.3390\/rs15061572","type":"journal-article","created":{"date-parts":[[2023,3,14]],"date-time":"2023-03-14T02:33:36Z","timestamp":1678761216000},"page":"1572","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["Optimization of Multi-Mission CubeSat Constellations with a Multi-Objective Genetic Algorithm"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9331-3633","authenticated-orcid":false,"given":"Shimeles Demissie","family":"Melaku","sequence":"first","affiliation":[{"name":"Aerospace System Engineering, University of Science and Technology, Daejeon 34113, Republic of Korea"}]},{"given":"Hae-Dong","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Aerospace and Software Engineering, Gyeongsang National University, Jinju 52828, Republic of Korea"}]}],"member":"1968","published-online":{"date-parts":[[2023,3,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1017","DOI":"10.1016\/j.asr.2017.11.019","article-title":"Analysis and design of Cubesat constellation for the Mediterranean south costal monitoring against illegal immigration","volume":"61","author":"Lazreg","year":"2018","journal-title":"Adv.
