Abstract
The desire to return humans to the moon has motivated the evaluation of existing lunar descent guidance algorithms and the development of new ideas. This paper outlines a design for a targeting algorithm that quickly and reliably generates a two-dimensional reference trajectory and a real-time three-dimensional guidance algorithm that can use this or any reference trajectory as its basis. The targeting algorithm is analytical in a nature and allows for updates to the reference in real time. Monte Carlo analysis demonstrates the reliable performance of the algorithms in both a general sense and for retargeting once the lunar descent has been initiated.
