However these methods classically ignore the fact that system is actually stochastic as they solve solution. In this paper, we discuss recent developments in robust methodology addressing nature of problems. This uncertainty due imperfect navigation solution, well presence dynamic models and...
This paper will provide an introduction and overview of Area-of-Effect Softbots (AoES), which are currently in development under a Phase 2 NASA Innovative Advanced Concepts (NIAC) project. AoES designed to operate proximity to, on the surface of, small asteroids support mining planetary defense missions. Their unique design capabilities dependent incorporation soft, compliant, lightweight materials. have large area-to-mass ratio allows them take advantage peculiarities dynamical environment...
This paper examines the ability of a bilinear tangent guidance law to perform continuous-thrust, single-burn orbital maneuvers in small-body environment (solar radiation pressure, etc.) and capability Newton–Raphson predictor–corrector algorithm free-time, state-to-state spacecraft on initial state perturbations. shows that low-thrust is able wide variety with thrust levels around asteroid Bennu. Additionally, this even high control authority, size perturbations can be corrected depends...
This paper presents a novel fuel-efficient continuous-thrust maneuver targeting (CTMT) algorithm that is capable of planning finite, continuous maneuvers in larger autonomous spacecraft guidance architecture. accomplished using constant-thrust bilinear tangent law conjunction with an optimal Lambert and Newton–Raphson predictor–corrector scheme. simple approach plethora different free-time fixed-time single-burn, burn–coast intercept, or burn–coast–burn from initial state/orbit to desired...
