Trajectory optimization using regularized variables. [PDF]
AIAA Journal, 1969 Summary: When the trajectory of a space vehicle passes through regions with significantly different gravitational force magnitudes, numerical accuracy requirements often necessitate extreme computer times. In celestial mechanics, regularizing transformations are used to eliminate computational and analytical problems that occur during close approaches ...
