Research on ZUPT technology for pedestrian navigation

When the satellite signal is blocked, the ground terminal cannot be accurately positioned because it cannot receive the satellite signal. In this case, it is necessary to study how to use other ways to achieve positioning and navigation. Inertial navigation inertial sensors to rely on sensing carrier acceleration and angular velocity, the position of the carrier can provide continuous in is not dependent on any external signal, speed and attitude, autonomous navigation carrier, and therefore can be used as a means to enhance the single satellite navigation and positioning. In this paper, we design a scheme to enhance the positioning accuracy by using the fusion of chip level MEMS inertial sensor and single satellite scanning position.
