In pursuit of that proficiency, this research develops a key capability of interest to mission planners; the ability of a deputy satellite to \"hover\" within a defined volume fixed in the vicinity of a chief satellite for an extended period of time. Previous research has developed initial methodologies for maintaining restricted teardrop hover orbits that exist in a plane fixed within the chief's local reference frame. These methods use the natural drift of the deputy satellite in the relative frame and impulsive thrust to keep the deputy in a bounded volume relative to the chief, but do not address fuel-optimality. This research extends and enhances that work by finding optimal trajectories, produced with discrete-thrusts, that minimize fuel spent per unit time and stay within the user-defined volume, thus providing a practical hover capability in the vicinity of the chief.\u003c\/p\u003e","brand":"Mia Karts","offers":[{"title":"Default Title","offer_id":51960693063968,"sku":"NEW1288311109","price":25.14,"currency_code":"USD","in_stock":false}],"url":"https:\/\/miakarts.com\/products\/optimal-control-strategies-for-constrained-relative-orbits-1288311109","provider":"Miakarts Books","version":"1.0","type":"link"}
