It's well known that the accuracy of the inertial navigation systems will rapidly degrades with time because of the measure sensor's error. Several variance techniques have been devised for the error modelling of this error by way of weighting functions, PSD, ARMA and NNs, etc. In this paper, we use the SVM(support vector machine) technique to predict the future noise coming from the measure sensors...
In order to restrain the influence of random disturbance on the attitude determination of in-motion rolling projectile, a new hybrid filtering algorithm, which combines unscented Kalman filter (UKF) with improved adaptive BP neural network based on particle swarm optimization (PSO), is proposed. When the attitude determination of rolling projectile is influenced by random disturbance, the output of...
Inertial-navigation system (INS) and global position system (GPS) technologies have been widely applied in many positioning and navigation applications. INS determines the position and the attitude of a moving vehicle in real time by processing the measurements of three-axis gyroscopes and three-axis accelerometers mounted along three mutually orthogonal directions. GPS, on the other hand, provides...
