High-degree cubature Kalman filter
The cubature Kalman filter (CKF), which is based on the third degree spherical–radial cubature rule, is numericallymore stable than the unscented Kalman filter (UKF) but less accurate than theGauss–Hermite quadrature filter (GHQF). To improve the performance of the CKF, a new class of CKFs with arbitrary degrees of accuracy in computing the spherical and radial integrals is proposed. The third-...
متن کاملOn Continuous-Discrete Cubature Kalman Filtering
This paper is concerned with application of cubature integration methods to Kalman filtering of discretely observed non-linear stochastic continuous-time systems. We compare two recently proposed variants of the continuous-discrete cubature Kalman filter (CD-CKF), which differ in the order how the discretization and the Gaussian approximation are done. Aside with theoretical analysis we test th...
متن کاملGPS/INS Integration for Vehicle Navigation based on INS Error Analysis in Kalman Filtering
The Global Positioning System (GPS) and an Inertial Navigation System (INS) are two basic navigation systems. Due to their complementary characters in many aspects, a GPS/INS integrated navigation system has been a hot research topic in the recent decade. The Micro Electrical Mechanical Sensors (MEMS) successfully solved the problems of price, size and weight with the traditional INS. Therefore...
متن کاملGPS/Pseudolite/SDINS Integration Approach for Kinematic Applications
This paper discusses the introduction of pseudolites (ground-based GPS-like signal transmitters) in existing integrated GPS/INS systems in order to provide higher availability, integrity and accuracy in a local area. Even though integrated GPS/INS systems can overcome inherent drawbacks of each component system (line-ofsight requirement for GPS, and INS errors that grow with time), performance ...
متن کاملNeural Network Aided Kalman Filtering for Integrated Gps/ins Geo-referencing Platform
Kalman filtering theory plays an important role in integrated GPS/INS georeference system design. A Kalman filter (KF) uses measurement updates to correct system states error and to limit the errors in navigation solutions. However, only when the system dynamic and measurement models are correctly defined, and the noise statistics for the process are completely known, a KF can optimally estimat...
