Abstract: A guided parafoil system for delivering lightweight payloads provides an accurate, small and low-cost delivery system for small payloads such as chemical sensor packages. The delivery system is adapted to fit along with the payload within a standardized canister. The delivery system includes a parafoil and a guidance control system that includes a global positioning system (GPS) receiver and an electronic compass to detect a deviation and bearing from a desired target. The parafoil is guided by a single motor that turns the parafoil in a horizontal direction perpendicular to the current direction of travel in response to deviations detected from a desired course. The desired course is initially linear until the system reaches a predetermined horizontal radius from the target and then the course becomes a circular path around and above the target.
