An optimization framework for cost effective design of refueling station infrastructure for alternative fuel vehicles

Historically, gasoline and diesel fuels have been used for transportation, but the possible decline of oil supplies in the future is forcing nations to consider alternative fuels. Most technically and economically feasible alternative fuels have a lower energy density than gasoline, which results in a shorter range for these vehicles. This necessitates a greater need for convenient access to re...

A Cooperative P2p Refueling Strategy for Circular Satellite Constellations

In this paper, we discuss the problem of peer-to-peer (P2P) refueling of satellites in a circular constellation. In particular, we propose a cooperative P2P (C-P2P) refueling strategy, in which the satellites involved in P2P maneuvers are allowed to engage in cooperative rendezvous. We discuss a formulation of the proposed C-P2P strategy and a methodology to determine the optimal C-P2P assignme...

A vision-based strategy for autonomous aerial refueling tasks

Autonomous aerial refueling is a key enabling technology for both manned and unmanned aircraft where extended flight duration or range are required. The results presentedwithin this paper offer one potential vision-based sensing solution, together with a unique test environment. A hierarchical visual tracking algorithm based on direct methods is proposed and developed for the purposes of tracki...
