SuperSmart Parachute Deployment Algorithm for MarsPinpoint Landing

摘要

An algorithm for choosing the parachute deployment point has been developed which is designed to reduce delivery errors at powered descent ignition during Entry / Descent / Landing (EDL) on a body with an atmosphere (e.g. Mars), consequently reducing the propellant required to achieve precise landing at a preselected target. This algorithm is designed to improve on the previously developed "Smart Chute" deployment algorithm by modeling the lander's trajectory during the parachute phase for improved targeting. Performance benefits are influenced by environmental factors, principally winds between chute deployment and ignition, which cause the lander to drift on the parachute.
