Abstract
The 99.73% minimum distance, denoted as 3, is the 0.27%-percentile in the distribution of the norm of the instantaneous relative position between two agents. Previously, 3 has been proposed as a probabilistic collision risk boundary for spacecraft formation flight under the assumption of Clohessy-Wiltshire (CW) relative orbital dynamics. In this case, agents with lesser separation than 3 have an instantaneous collision probability higher than 0.27%. This work validates the foregoing interpretation of 3 by showing that small changes to the target probability of 3 also result in small changes to 3 itself.
