Maneuvers such as circular-shaped formation flying, obstacle avoidance, and docking are first developed. A modified, time-varying guidance law using a proportional-controller is then developed, capable of performing such maneuvers while holding commanded thrusts under user-defined thresholds. Applications\/limitations of this new guidance law are discussed. Numerical simulation results are presented.<\/p>\n","protected":false},"author":2,"featured_media":0,"template":"","meta":{"_acf_changed":false,"footnotes":"","_links_to":"","_links_to_target":""},"cu_event_type":[],"cu_event_audience":[],"class_list":["post-859","cu_event","type-cu_event","status-publish","hentry"],"acf":{"cu_event_start_date":"2017-06-01T00:00:00","cu_event_end_date":"2017-06-01T00:00:00","cu_event_location_type":"in-person","cu_event_meeting_address_type":"on-campus","cu_building":false,"cu_event_meeting_room":"","cu_event_meeting_address_full":null,"cu_event_virtual_type":"tbd","cu_event_virtual_meeting_link":"","cu_post_thumbnail":false,"cu_event_cost":"","cu_event_registration":"","cu_event_secondary_button":"","cu_event_contact_name":"","cu_event_email":"","cu_event_phone":""},"_links":{"self":[{"href":"https:\/\/carleton.ca\/spacecraft\/wp-json\/wp\/v2\/cu_event\/859","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/carleton.ca\/spacecraft\/wp-json\/wp\/v2\/cu_event"}],"about":[{"href":"https:\/\/carleton.ca\/spacecraft\/wp-json\/wp\/v2\/types\/cu_event"}],"author":[{"embeddable":true,"href":"https:\/\/carleton.ca\/spacecraft\/wp-json\/wp\/v2\/users\/2"}],"version-history":[{"count":1,"href":"https:\/\/carleton.ca\/spacecraft\/wp-json\/wp\/v2\/cu_event\/859\/revisions"}],"predecessor-version":[{"id":860,"href":"https:\/\/carleton.ca\/spacecraft\/wp-json\/wp\/v2\/cu_event\/859\/revisions\/860"}],"wp:attachment":[{"href":"https:\/\/carleton.ca\/spacecraft\/wp-json\/wp\/v2\/media?parent=859"}],"wp:term":[{"taxonomy":"cu_event_type","embeddable":true,"href":"https:\/\/carleton.ca\/spacecraft\/wp-json\/wp\/v2\/cu_event_type?post=859"},{"taxonomy":"cu_event_audience","embeddable":true,"href":"https:\/\/carleton.ca\/spacecraft\/wp-json\/wp\/v2\/cu_event_audience?post=859"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
