Micro Electro Mechanical Systems (MEMS) are a versatile technology encompassing applications in sensing, actuation, and control. This research paper focuses on the significance of MEMS in aerospace due to their compact size, exceptional precision, and energy efficiency. The primary objective is to investigate the utilization of Inertial Measurement Units (IMUs) for navigation, guidance, and control in aerospace applications. IMUs are adept at measuring both linear and angular motions, making them invaluable tools in aerospace systems. Within the navigation system, pressure is applied along the X-axis to analyze the angle of deviation, which is subsequently measured along the Z-axis. By effectively constraining the Y-axis, pressure-angle deviation analysis is conducted using diverse mesh analysis techniques. The research aims to meticulously design and evaluate the model's accuracy and sensitivity using COMSOL MULTIPHYSICS. The ultimate goal is to achieve superior precision sensing and control capabilities specifically tailored for the demands of the aerospace domain.
