The Conjunction Assessment task at NASA Goddard Space Flight Center provides conjunction risk assessment for many NASA robotic missions. These risk assessments are based on several figures of merit, such as miss distance, Probability of Collision (Pc), and orbit determination solution quality. However, these individual metrics do not singly capture the overall risk associated with a conjunction, making it difficult for someone without this complete understanding to take action, such as an avoidance maneuver. The goal of this analysis is to introduce a single risk index metric that can easily convey the level of risk without all the technical details. The proposed index is called the conjunction “F-value.” This paper presents the concept of the F-value and the tuning of the metric for use in routine Conjunction Assessment operations.
