Proposed framework reduces spatial uncertainty in deep-space navigation using cosmic references, suggesting improved navigation accuracy.
"This paper introduces the Anisotropy-Based Navigation (ABN) framework, a proposed absolute cosmic reference system. By utilizing the Cosmic Microwave Background (CMB) Dipole as a directional axis and Baryon Acoustic Oscillations (BAO) as a standard ruler, the framework aims to reduce spatial uncertainty in deep-space navigation by a factor of 2000."
