Maneuver design for Galileo Jupiter approach and orbital operations
Following the successful release of the Galileo probe, the navigation efforts were focused on the implementation of the critical Io approach and the Jupiter orbit insertion strategy. The actual in-flight events on the approach phase affected the strategy. The most significant event was the onboard tape recorder anomaly, and it is shown that this anomaly affected the plans and assumptions of the navigation strategy for the approach and orbit insertion. The analysis, constraints, contingency planning and design evolution of trajectory correction maneuvers which enabled the continuation of the mission, are reported on. The Jupiter approach and initial orbit navigation strategy is presented in order to verify the viability of the strategy under nominal circumstances, and future mission operations plans are described.
(abstract) Maneuver Design for Galileo Asteroid Flybys
This paper will address the trajectory correction maneuvers (TCMs) which enabled the successful completion of the circuitous VEEGA trajectory while providing for the first ever encounters with main-belt asteroids.
