Definition

An autonomous navigation method for satellites in libration point orbits proposed by Hill and Born, using inter-satellite range data to determine orbits without ground support. Since its proposal in 2005, it has been widely used in autonomous navigation studies for Halo orbit satellites. Its core principle is leveraging the non-rotationally symmetric force environment near libration points to overcome the rank-deficient problem inherent in conventional satellite navigation.
