Abstract
A predictive guidance algorithm maneuvers a fly-by vehicle in a direction towards an object vehicle with a time varying line-of-sight rate. After initial predictive guidance, a modified proportional navigation maneuvering phase accelerates the fly-by vehicle towards an object vehicle on an intercept line-of-sight path. The proportion navigation maneuvering is terminated prior to interception so that the fly-by vehicle does not intercept the object vehicle, but rather flies by the object vehicle at a desired miss distance, well suited for fly-by monitoring and imaging missions of space vehicles and planetary objects.
