Inertial measurement units, or IMUs, serve as effective tracking devices when used in sophisticated aerospace control and navigational systems. This tracking potential, coupled with ever advancing technology that permits IMUs to become smaller and more compact, is allowing IMUs to gain popularity in a many areas of research beyond the areas of aerospace. Using an IMU based on microelectromechanical (MEMS) technology, this document investigates an IMU’s ability to track complex, short range motions such as golf swings. To prepare the IMU, an accurate, yet quick, calibration procedure is proposed and illustrated to show the tools and equipment necessary for this approach. Once calibrated, experimental results from static and dynamic tests are compared to corresponding analytical results to help comprehend and confirm the IMU readings. The IMU is then applied to a series of short range motions for reliability and performance testing.
