“…Surrogate models have a rich history in design and analysis for a variety of aerospace disciplines, including structural design (Barthelemy and Haftka, 1993), rocket engine component design (Farmer et al, 2000;Papila et al, 2002;Vaidyanathan et al, 2000), cavitating flows (Goel et al, (Glaz et al, 2009), and missile performance (Riddle et al, 2009). More recently, surrogate modeling has been applied to the field of astrodynamics, including interplanetary transfers and satellite constellation design (Gano et al, 2006), low thrust trajectory optimization (Peng et al, 2013), low thrust controls (Ghosh and Conway, 2013), and orbit uncertainty propagation . This section provides the necessary background on surrogate models and the model development process for application to the problem of spacecraft rendezvous in the CRTBP.…”
