Sigma 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...
متن کاملParticle Filter for Underwater Terrain Navigation
In an earlier contribution we proposed a particle filter for underwater (UW) navigation, and applied it to an experimental trajectory. Here we focus on performance improvements and analysis. First, the Cramér Rao lower bound (CRLB) along the experimental trajectory is computed, which is only slightly lower than the particle filter estimate after initial transients. Simple rule of thumbs for how...
متن کاملSigma-Point Kalman Filters for Integrated Navigation
Core to integrated navigation systems is the concept of fusing noisy observations from GPS, Inertial Measurement Units (IMU), and other available sensors. The current industry standard and most widely used algorithm for this purpose is the extended Kalman filter (EKF) [6]. The EKF combines the sensor measurements with predictions coming from a model of vehicle motion (either dynamic or kinemati...
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...
