A new study has explored how the bicircular restricted four-body problem (BCR4BP) can be utilized to optimize satellite formation dynamics in cislunar space. This theoretical approach offers a more precise framework for understanding and predicting spacecraft motion in the complex region between the Earth and the Moon, overcoming the limitations of more simplified models. This advancement is crucial for future missions requiring stable and coordinated satellite constellations in this area of growing interest.

Traditionally, trajectory design in cislunar space has relied on the circular restricted three-body problem (CR3BP), which considers the gravitational influence of two primary bodies (Earth and Moon) on a body of negligible mass. However, the BCR4BP introduces a fourth body, or considers the primaries' orbits as elliptical, allowing for a more faithful modeling of additional perturbations affecting satellites, such as solar radiation pressure or the influence of a significant third celestial body. The current research focuses on how these additional complexities can be leveraged to maintain satellite formations with greater precision and lower fuel consumption.
