Inertial Measurement Unit Simulator

During the last few years microminiaturized inertial sensors were introduced in many applications. Their small size, low power consumption, rugged construction open doors to many areas of implementation. The main drawback of these sensors is the influence of different type of errors, leading to an unavoidable wrong position and orientation estimation. In the paper a simulator of Inertial Measurement Unit is proposed. The simulator is a tool for assistance of trajectory set up and on the base of input data it generates IMU output according given error/noise parameters. It allows us to simulate different types of IMUs based on prior knowledge of the IMU error’s properties. One of the main goals in developing of the simulator is to validate new methods involving inertial technology. Something more, the simulator is an excellent tool for tuning complex filtering procedures and enhancing navigation accuracy. The simulation of different scenarios gives more information to receive better understanding of the weight of different sensor noises and errors on the final results.
