There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Full Summary:
Minimum-Fuel Powered Descent in the Presence of Random Disturbances
Jack's Project ThumbnailIt has recently been shown that minimum-fuel powered descent guidance can be solved onboard as a convex optimization problem. It therefore presents itself as a promising technology to enable future planetary exploration missions. However, since this approach is formulated as a deterministic optimal control problem, the resulting guidance law is only designed for a single pair of initial and target states without external disturbances.
We attempt to extend this approach to the more general case of steering initial position and velocity distributions to target distributions, while considering Brownian motion process noise acting on the system.
