| contents | In this work we present more comprehensive evaluations on our airborne Gimbal mounted inertial measurement unit (IMU) signal simulator which also considers flight dynamic model (FDM). A flexible IMU signal simulator is an enabling tool in design, development, improvement, test and verification of aided inertial navigation systems (INS). Efforts by other researchers had been concentrated on simulation of the strapdown INS (SINS) with the IMU rigidly attached to the moving body frame. However custom airborne surveying/mapping applications that need pointing and stabilizing camera or any other surveying sensor, require mounting the IMU beside the sensor on a Gimbal onboard the airframe. Hence the proposed Gimbal mounted IMU signal simulator is of interest whilst itself requires further analysis and verifications. Extended evaluation results in terms of both unit tests and functional/integration tests (using aided inertial navigation algorithms with variable/dynamic lever arms), verifies the simulator and its applicability for the mentioned tasks. We have further packaged and published our MATLAB code for the proposed simulator as an open source GitHub repository. |
