This study aims to enhance the accuracy of the commercial Inertial Measurement Unit (IMU) developed using the advanced Micro-Electro-Mechanical System (MEMS) by using the epoch analysis technique. The epoch analysis approach has been established to quantify the observation data from static measurement stations. A statistical approach is used to: 1) eliminate gross errors; 2) determine the appropriate data (filter); 3) estimate future values; and 4) for data evaluation. The main attribute of epoch analysis is its treatment of redundancy in the observed data by taking into account the frequencies that are found within it. In a dynamic application, epoch analysis is used by examining the instantaneous position. In this paper, the competency of epoch analysis in reducing the commercial IMU data for geometrical image correction is presented.
