“…In both types of recovery, due to the low engine startup height in the final precise landing phase, a large positional deviation will cause the RCV to be unable to land accurately [2,3]. Therefore, it is necessary to propose an entry aerosphere guidance method that is suitable for the vertical recovery of the RCV to meet the terminal constraint requirements.…”

“…Successive convexification allows to handle certain features that, depending on the target body, may play a critical role for D&L, such as high-order gravitational harmonics, nonlinear aerodynamic forces, non-convex keep-out zones and also free final-time, see (Liu & Lu, 2014;Mao et al, 2016;Lu, 2018) and references therein.…”

“…analyze the bang-bang profile)and 2) find the optimal numbers of burn times. Importantly, the advantage over G-FOLD is due to its simplicity and flexibility as it does not require customization of the algorithm [12]. However, UPG has the disadvan-60 tage that both inequality and thrust direction constraints are generally difficult to enforce [12].…”
