Definition

The property of Halo orbit families near libration points where, in a specific spatial region, only one unique periodic orbit exists for given initial conditions. This uniqueness arises from the strong asymmetry of the CRTBP gravitational field near collinear libration points, making Halo orbits inherently carry absolute position information that compensates for the absolute orientation deficiency in two-body SST orbit determination.
