Stable Low Lunar Orbit with Near-Zero Delta-V: A Dynamically-Controlled Solution in Earth's Rotating Frame

This preprint introduces a novel class of dynamically-stabilized low lunar orbits within an Earth-centric rotating frame. By applying a full 3D feedback control on the angular velocity vector, the system conserves total angular momentum across the Earth–Moon–satellite system. Simulations over 30 days demonstrate stable orbit retention with near-zero delta-V expenditure (< 1 m/s), outperforming established NRHO and DRO trajectories. This discovery opens up new possibilities for ultra-low energy lunar stationkeeping and long-duration orbit planning. The preprint includes embedded simulation code, delta-V tables, and trajectory visualizations for full reproducibility and independent validation.

See README.rtf for details on how the embedded simulation code can be used.
