Inertial laboratory simulation

In early 2015 an inertial laboratory will be installed at TUM´s Institute of Flight System Dynamics (FSD). In cooperation with ACUTRONIC Switzerland Ltd. an AC3350 three-axis motion simulator will be used to investigate inertial sensor calibration techniques, as well as error influences of the whole laboratory environment. To identify and assess possible influences on the laboratory´s quality a simulation of the whole calibration process, including error models of the laboratory environment, the motion simulator and the unit under test has been created. The article presents an overview of identified error sources in the inertial sensor calibration process. Typical error sources are discussed exemplarily for the future Inertial Laboratory. Finally the influence of these errors on a symmetric six-pose calibration process is illustrated using preliminary simulation results.
