Technological advances in both GPS and low cost micro-electro mechanical system (MEMS)-based inertial sensors enabled monitoring the location of moving platforms for numerous positioning and navigation (POS/NAV) applications. When miniaturized inside any moving platforms, MEMS-based inertial navigation system (INS) can be integrated with GPS and enhance the performance in denied GPS environments (like...
A seamless changing method for AUV integrated navigation system was proposed considering the SINS/DVL and Compass/DVL integrated navigation method have their own advantage for linear motion and curvilinear motion. Bearing consistent check combining with the measure remnant method was discussed as the maneuver checking method, and the adaptive Kalman filter was used by SINS/DVL integrated navigation...
In this paper the UDUT continuous-discrete unscented Kalman filter (UKF) for state estimation of continuous-time nonlinear systems is proposed. UDUT scalar update is introduced into the measurement update procedure of continuous-discrete UKF (CDUKF). It is pointed out that this form is sometimes more efficient than the standard CDUKF. Computational complexity of the two forms of CDUKF is analyzed...
Average consensus algorithms are protocols to compute the average value of all sensor measurements via near neighbors communications. They offer a natural tradeoff between the number of messages exchanged among terminals and the accuracy in the computation. Most of the models adopted for the message exchange in the literature, however, neither include explicit rate constraints nor explore the rate...
