Definition
A correction applied to orbital calculations accounting for Earth's non-spherical gravitational effect, primarily from the J2 oblateness term. The paper introduces this correction in free-return trajectory design, using an improved multiple-conic method to enhance accuracy under Earth's oblateness effects.
Application Value
