Laboratory Motion Testing of MEMS Inertial Measurement Units (IMU)

Robert W. Mitchell

Abstract:	As applications increase in the usage of MEMS IMU devices, test equipment as motion simulators must respond with cost-effective solutions. The MEMS (Micro Electro Mechanical System) device mounts to a motion simulator to provide a realistic flight scenario. The flight motion simulator provides position, rate, and acceleration test data. The output of the MEMS device is compared to the position feedback transducers of the motion simulator. This technique is used for development, calibration, or troubleshooting of the MEMS device. Various types of tests characterize the signal output of the MEMS device. This paper discusses the test scenarios, error types, the error characteristics, and the typical performance values for a two-axis flight motion system.
