Comparison between extended Kalman filter and Sigma-Points Kalman filters applied to integrated navigation system INS (inertial Navigation System)/GPS (Global Positioning system) SA (selective Availibilty)
The application of the divided derivative filters is described, applied and compared to the most popular tool in estimation , the extended Kalman filter (EKF). In our work the first order divided difference filter and the second order divided difference filter were simulated and applied to integrated navigation system including inertial measurement unit (i) and global positioning system. These ...
متن کاملSigma Point Kalman Filter for Underwater Terrain-based Navigation
Precise underwater navigation is crucial in a number of marine applications. Navigation of most autonomous underwater vehicles (AUVs) is based on inertial navigation. Such navigation systems drift off with time and external fixes are needed. This paper concentrates on one such method, namely terrain based navigation, where position fixes are found by comparing measurements with a prior map. Non...

In this paper, a mechanism is designed for integration of inertial navigation system information (INS) and global positioning system information (GPS). In this type of system a series of mathematical and filtering algorithms with Tightly Coupled techniques with several objectives such as application of integrated navigation algorithms, precise calculation of flying object position, speed and at...
متن کاملMobile Robot Navigation Error Handling Using an Extended Kalman Filter
Obviously navigation is one of the most complicated issues in mobile robots. Intelligent algorithms are often used for error handling in robot navigation. This Paper deals with the problem of Inertial Measurement Unit (IMU) error handling by using Extended Kalman Filter (EKF) as an Expert Algorithms. Our focus is put on the field of mobile robot navigation in the 2D environments. The main chall...
متن کاملIntegrated Navigation System Using Sigma-Point Kalman Filter and Particle Filter
The paper describes integration of Inertial Navigation System (INS) and Global Positioning System (GPS) navigation systems using new approaches for navigation information processing based on efficient SigmaPoint Kalman filtering and Particle filtering. The paper points out the inherent shortcomings in using the linearization techniques in standard Kalman filters (like Linearized Kalman filter o...
