W. Paek et al. (2017),\u00a0<i>JBIS<\/i>,\u00a0<b>70<\/b>, pp.19-35<\/h3>\n<p><b>Refcode<\/b>: 2017.70.19<\/p>\n<p><b>Abstract:<\/b><br \/>\nRemote sensing missions for disaster monitoring or reconnaissance are target-agnostic in that target locations are unknown a priori. Therefore, reconfigurability in satellite orbits can increase responsiveness and quality of imagery data. This paper uses a systems engineering approach to develop an optimization tool for reconfigurable constellations (ReCon). The tool concurrently optimizes the individual satellite design and the constellation geometry. The proposed concept of operations of a ReCon has two operational modes: global observation mode (GOM) and regional observation mode (ROM). Satellites in GOM have drifting ground tracks that provide a global coverage, and ROM features repeating ground tracks (RGT) that increase the access frequency to a particular target. A weighted-sum genetic algorithm (GA) is used to identify non-dominated optimal solutions along a Pareto front in the multi-objective trade space. In addition to demonstrating the technical feasibility of a ReCon, this paper proposes staged deployment strategies to minimize contingent risks such as launch failures and market uncertainties.<\/p>\n","protected":false},"featured_media":9627,"template":"","meta":[],"pwb-brand":[],"product_brand":[],"product_cat":[56,59,167],"product_tag":[2724,1696,739,2723,2722],"class_list":["post-9626","product","type-product","status-publish","has-post-thumbnail","product_cat-journal-of-the-bis","product_cat-papers","product_cat-2017papers","product_tag-genetic-algorithms","product_tag-reconfigurability","product_tag-remote-sensing","product_tag-repeating-ground-tracks","product_tag-satellite-constellations","first","instock","downloadable","virtual","purchasable","product-type-simple","czr-hentry"],"jetpack_sharing_enabled":true,"brands":[],"_links":{"self":[{"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/product\/9626","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/media\/9627"}],"wp:attachment":[{"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/media?parent=9626"}],"wp:term":[{"taxonomy":"pwb-brand","embeddable":true,"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/pwb-brand?post=9626"},{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/product_brand?post=9626"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/product_cat?post=9626"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/product_tag?post=9626"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
