To that end, we introduce a generalization of the 2D Necklace Flower Constellations formulation to adapt the methodology to constellations whose satellites have different mission requirements, while still allowing to reduce the searching space in satellite constellation design. Moreover, this design is combined with its dual distribution in the Earth Centered–Earth Fixed reference frame to obtain additional information about the dynamic of the system, including the sub-satellite point revisiting time, or the relative to Earth distribution. This is used to optimize the constellation in terms of maximum uniformity of the distribution with respect to the Earth. Finally, a detailed example of application of this design methodology is presented, where a constellation based on satellites with different mission requirements is considered. 000130453 536__ $$9info:eu-repo/grantAgreement/ES/DGA-FSE/E24-17R$$9info:eu-repo/grantAgreement/ES/MINECO-AEI-FEDER/ESP2017-87113-R 000130453 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc-nd$$uhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/ 000130453 590__ $$a2.954$$b2021 000130453 591__ $$aENGINEERING, AEROSPACE$$b6 / 34 = 0.176$$c2021$$dQ1$$eT1 000130453 592__ $$a1.0$$b2021 000130453 593__ $$aAerospace Engineering$$c2021$$dQ1 000130453 594__ $$a5.7$$b2021 000130453 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/submittedVersion 000130453 700__ $$0(orcid)0000-0002-7620-4523$$aCasanova, D. 000130453 700__ $$0(orcid)0000-0003-4859-7224$$aTresaco, E. 000130453 773__ $$g178 (2021), 203-215$$pActa astronaut.$$tActa Astronautica$$x0094-5765 000130453 8564_ $$s968759$$uhttps://zaguan.unizar.es/record/130453/files/texto_completo.pdf$$yPreprint 000130453 8564_ $$s1055794$$uhttps://zaguan.unizar.es/record/130453/files/texto_completo.jpg?subformat=icon$$xicon$$yPreprint 000130453 909CO $$ooai:zaguan.unizar.es:130453$$particulos$$pdriver 000130453 951__ $$a2024-01-25-15:11:55 000130453 980__ $$aARTICLE
