Augmenting Parachute Testing and Evaluation Using GPS-Based Position and Velocity

C. Schutte, M. Miller, J. Raquet

Abstract:	Development of new parachute systems and modifications to existing systems require extensive testing to ensure a safe and controlled landing for its user or payload. To thoroughly evaluate these systems, large amounts of data must be collected and analyzed. Current testing is transitioning from older more expensive testing methods using telemetry, radars, lasers, and high-resolution photography equipment to smaller off-the-shelf data collection methods that are more reliable and cost effective. This paper presents the design and test results from a Global Positioning System (GPS)-based system capable of monitoring several parameters of interest for parachute testing. This portable system can easily be integrated into a test manikin or payload. Small, low-power, lightweight GPS receivers, capable of handling high-accelerations, are mounted on the desired test article to collect position, velocity, and attitude data from initiation until the final landing. The GPS-based system will be used to augment the telemetry, photographic, and on-board data collection systems currently being used to improve tracking accuracy and reduce testing costs.
