Abstract
Rendezvous and intercept missions to smaller asteroids require precision guidance and control in the terminal mission phase. The zero-effort-miss (ZEM) and zero-effort-velocity (ZEV) information are used to formulate autonomous feedback guidance laws. A terminal-phase guidance strategy for a variety of intercept missions is developed. Different types of navigation information are assumed to be available from different spacecraft configurations and hardware choices. Guidance laws are developed for different mission configuration options. Guidance laws for both rendezvous and impact are studied. Optimal feedback guidance laws are also investigated for asteroid intercept/rendezvous missions. Simulations show the effectiveness of the various guidance laws.
