PDF document and a MATLAB script called tli_sweep_otb that can be used to perform a parametric analysis of lunar transfer trajectories. The software assumes that trans-lunar injection (TLI) occurs impulsively from a circular Earth park orbit. The software solves for the minimum TLI delta-v using a two-body Lambert solution for the transfer trajectory from the Earth park orbit to the center of the moon. This computer program uses the Optimization Toolbox to solve this classic trajectory optimization problem. The lunar coordinates required by the software are computed using the JPL DE430 ephemeris.
