Abstract:

This report discusses general solutions to the spaceflight intercept problem between moving source and target vehicles, under the constraint that only one limited thrust burn is permitted. This one burn is approximated as an instantaneous change in velocity, deltav. Given first is a discussion of the solution space, aided by Lamberts theorem. Generally, two solutions and sometimes more to the posed intercept problem exist for a given launch time. Although previous solution techniques in the literature concentrate on finding the minimum time solution, both solutions are significant from an operational and a theoretical standpoint. Next, exact derivatives for two different operational requirements are derived, which facilitate finding all solutions to the intercept problem. Finally, example numerical problems solved by the Antitactical Ballistic Missile Global Effectiveness Model AGEM are presented to demonstrate the solution process for both operational requirements.
