Apollo powered descent guidance (APDG) law enabled Apollo lunar module to land on the Moon successfully. Since then, in the past 50 years, APDG and several of its variants have been used in numerous planetary landing studies and missions. As its formulation does not consider drag force, the APDG law is typically used for powered descent landing in rarefied environments like the Moon and Mars. In this paper, we extend the application of the APDG law to atmospheric environments by aiding it with an acceleration controller. The proposed acceleration control strategy not only compensates for the estimated aerodynamic drag, but also mitigates the uncertainties in the thrust produced, thus maintaining the desired acceleration. To demonstrate the efficacy, we provide results of simulated powered descent landing of a reusable launch vehicle (RLV) on Earth using the proposed acceleration control strategy along with the APDG law. © 2022 Elsevier B.V..
