- W2903670135 abstract "An inertial sensor-based pedestrian navigation system, especially a navigation system using a Pedestrian Dead Reckoning (PDR) algorithm, is usually navigated with a Zero Velocity Update (ZUPT) algorithm to improve navigation and positioning Accuracy. The rich navigation sensor in smartphone makes it possible to use smartphone as the medium of pedestrian navigation. In fact, the self-contained low-cost inertial sensor of smartphone often needs such as ZUPT algorithms to suppress the rapid divergence of error, however, most traditional ZUPT algorithms putting the sensors on the foot, which make it impossible to detect a clear zero-speed moment for smartphone because we usually use smartphone with hand not put it on the foot and the traditional ZUPT algorithm can’t work. In this paper a Simulate-Zero Velocity Update (S-ZUPT) algorithm is proposed. The S-ZUPT algorithm detects the pedestrian walking steps through the accelerometer information collected by the smartphone, and carries out the Kalman Filter algorithm between the two steps moments to restrain the heading divergence caused by the low-precision sensors from the smartphone and improve navigation accuracy. Experiments show that the using S-ZUPT algorithm can effectively restrain the divergence of heading, reduce the error between the navigation route and the actual route, improving navigation accuracy." @default.
