Thrusting Trajectory Minimization Program for Orbital Transfer Maneuvers
"A computer program has been designed which determines the minimum-burn-time, thrusting, transfer trajectory between two Keplerian orbits. The minimization equations are formulated with constant Lagrange multipliers and solved numerically with the Newton-Raphson method. The solution obtained in this paper is not truly optimum because the control vector has been restricted to constant values (i.e., to be optimum the control vector should be a function of time)."--Page i
Planetary Spacecraft Navigation
In this new edition, the authors James Miller and Connie Weeks dive deeper into how computer programming has assisted with planetary spacecraft navigation; evaluating real-world results and relying on complex mathematical theory to observe advancements made in this rapidly accelerating field. This textbook introduces the theories and practical procedures used in planetary spacecraft navigation. Written by a former member of NASA's Jet Propulsion Laboratory (JPL) navigation team with his co-author, it delves into the mathematics behind modern digital navigation programs, as well as the numerous technological resources used by JPL as a key player in the field. In addition, the text offers an analysis of navigation theory application in recent missions, with the goal of showing students the relationship between navigation theory and the real-world orchestration of mission operations.
