The simulation procedure for GNSS-based position estimation of a launch vehicle in a gravity turn trajectory is presented. A detailed mathematical model of the dynamics of a multi-stage launch vehicle is developed. In the mathematical model, the …
The Extended Kalman Filter (EKF) is a widely used estimation technique which combines the knowledge of the dynamics of the user vehicle motion with the GNSS measurements for robust and more accurate position solutions. However, the EKF approximates …
Ground simulation is essential for assessing the performance of space-borne Global Navigation Satellite System (GNSS) based positioning algorithm and hardware. SPIRENT GNSS simulator is widely used for establishing the simulation environment. Precise …
