Quality control theory in terms of testing residuals has been proven to be an effective approach to deal with cycle slips. The integrated processing of multi-GNSS observations can further improve the reliability of cycle slip handling when using the residual snooping method. In this study, we investigated the integrated technique using the combined GPS/Galileo time-differenced observations for cycle...
The Chinese BeiDou Navigation Satellite System has shown potential for precise positioning with a comparable accuracy to that of the Global Positioning System (GPS) at the centimeter level for the horizontal component and the sub-centimeter level for the vertical component. However, a longer convergence time limits the performance of BeiDou precise point positioning (PPP) compared to the GPS PPP solutions...
This paper focuses on the control strategy to be used to parallel hybrid electric vehicles (HEVs). A model-based strategy for the fuel-optimal control is presented. The torque split control problem of the vehicle is formulated as an optimal control of switched system. The optimal control problem of such switched system is formulated into two stage optimization problem. The dynamic programming is utilized...
