Filtering methods of the inertial position measuring system

摘要

This paper describes a part of experimental project focused on inertial position measurement. Paper aims to filtering process of position and attitude estimation. In addition, the position evaluation process contains three filtering steps. Those steps are described separately. Inertial measuring unit (IMU) use a MEMS (Microelectromechanical Systems) technology sensors in specific application. This application is a tracking of the aerobatic aircraft flight path. Measurement by MEMS inertial sensors in this application is influenced by many types of noise. Described three step filtering process is trying to remove position and attitude error as much as possible.
